In a hobby where some people don't bat an eye at dropping thousands of dollars I'm surprised there aren't more of these expensive straps.

Great video, many thanks. Worth every penny and now on my list to buy. Best wishes from London, England

Excellent review. Purchased the blue version after seeing your review.

Looks great, deffo will buy one in the future, looks class on your Samurai. Great vid.

I own 2 Isofrane straps for about 10 years and they are worth every penny and still feel like new great straps

Never heard of Aquatico, nice selection. Thanks Dave!

I'd never pay this much for a strap. For not much more money I got my San Martin 62MAS homage. Which is fantastic.

Great review! Great music!

Been wearing these for over 10 years, will always wear these Simply the best, most comfortable strap you can treat yourself to

I have a black one on my Glycine Combat Sub, and honestly, the thing that for the most part made me spend a 140 € (yes euros) on it was the promise of a rubber strap that would NOT be a magnet for dust and lint that you feel you need to clean twice a day. And its not an empty claim, Isofrane delivered. Plus ofc its comfy and a true icon.

My new Phoibos Bronze Leviathan 45mm has a leather strap that has the exact same buckle design. I have never seen such a wide pin in the buckle and it's the best strap I have. See screw in buckle design and it came in with a similar rubber strap

As far as I understand that strap is priced at $140. In the actual market, where a many customers are wearing diving watches because of the look, not because of particularly diving, I think they look for a strap that makes the watch more attractive, more fashionable, more of an accessory they can combine and blend in different styles. I do not see that in that strap; I actually perceive watches going "down" with it, the Aquatico for instance. The roughness of a 3.xx mm strap with abrupt cuts and angles takes away the beauty or softness of the watch. Regarding quality: yes, depending on the mix of polymers used in plastic molding you get the described quality. Now , What is the purpose of that? If roughness look is the goal, Why Casio don't do that with G-Shocks? ... too expensive. So, no need for an improved material. My personal opinion: I do not see that product making it.

I just received a ARAGON 42 mm Dive Watch with a silicone strap that's great $179 , I can't see paying $100 for a rubber strap ! You should do a review of the watch , incredible watch at that price !

Good review, as usual. Definitely a nice strap, too--but not really sure you make the case for featuring it on a budget-priced watch review channel. Always looking forward to your vids!

I bought three haha I have three diver watches I absolutely adore and after the first one I wanted the best for the other two too. Superb straps, incredibly comfortable.

Oooh the blue one would look great with my Citizen Promaster NY0040 Blue Dial diver!!! (which is also ISO Certified)

Very aesthetically pleasing. Any good quality rubber strap should require zero break in time, and shouldn't cost cost this much though. The Isofrane has something of a cult status but like most products that achieve this you end up paying a premium for it. It is a good product but there are others that are also made from Italian rubber available for a third of the price. Also pleasantly scented and made in Italy, also with the branding on the inside of the substantial buckle. Not that it takes anything away from the Isofrane which remain incredibly comfortable and practical, not to mention the rugged good looks. The only thing I'm not keen on is that you're limited to 1.8mm spring bars, which seem a little feeble for such a macho design, they should really be updated to accommodate 2.5mm spring bars. Excellent video thanks.

Look also at Crafter Blue, really great straps for 50-70€.... I have them on Seiko's an Spinnaker's!....

This strap came standard with my Aquatico Super Charger Pilot One. It's 98 procent the same strap exept no "made in Italy" and the 2nd strapholder is not crooked. -The best strap I've ever owned.

These are the best rubber straps I own. Got two and one still has a nice smell after about 3 years ! I’ve had a few copy’s but they didn’t come close. Good review 👍🏻🇬🇧

These days most divers utilize dive computers. I am also not a budget watch buyer. I have an Isofrane on both my Doxa and Squale watch. The fit is excellent and very comfortable on the wrist. I definitely believe that these straps are worth the price. I also like sailcloth straps and in my opinion, Artem is the wisest way to spend your money.

LOL - the Aquatico I would say has a bit of inspiration from the Borealis Bullshark.

Try borealis vulcanized rubber straps. It is exactly the same as this one, and it costs 35 bucks. 140 for this is just absurd.

Im sure it's great but I love my Barton rubber straps .Top quality and super comfortable as well as great value .

Can't disagree about the Isofrane quality but, Helson on bracelet includes a Cuda rubber strap identical to Isofrane. I say identical because I owned and still own a few. The Cuda comes with the Helson in its leather pouch, it is part of the package and of course there's no additional charge. There's nothing wrong with the Isofrane price, it could have been a bit lower just so the low to mid range watch collectors would go for it. After all, once the price goes over 90 bucks, there are some other brands that offer exquisite quality. RubberB/Evererest. Those two might be the only straps I've used and kept looking great after 2 full sea seasons. Of course, the rubber/silicon ain't steel and in time will at least shine at the spots of contact or rubbing.

Great video Dave really hope you're going to keep the blue on and give away the black one...

I might pay that much unless I could find a similar quality strap at a better price. I want to see how it stood the test of time. My victorinox was a display watch that came with a rubber strap that was already cracked and worn from gentle use.

great review DAVE , I had try different straps leather and rubber , and the ISO frame blows away anything under the SUN for any one out there who is thinking of purshasing one, you will not regret it. GO FOR IT...

Steeldive uses similar straps on some watches. Costs 60% of this strap - WITH the watch. 🤣

I own 3 of them. A dark grey one and and an orange one for my Planet ocean Chronograph. And a black one for my Rolex Sub. Best rubber straps for tool watches by a landslide. Cool fact: isofrane was an OEM option on the original Omega Ploprof back in the 1970s. If omega used it as a factory option at one point, you know it’s a good strap.

OK, this is an old video. I was just looking for a quality rubber strap to replace the original one on my Seiko SPB053, one of the most beautiful diver watches ever made with a blue dial. I was hoping that you going to mention the exact length of the strap.

I own a fair few good natural rubber straps: Hirsch Extreme, Hirsch Pure, Bonetto Cinturini, etc. I also own an Isofrane and several Borealis straps. The Isofrane is definitely the best one of the bunch. Though if you're worried about the cost, the Borealis is a close second. I do have a caveat to that: Borealis's buckles are not very good in terms of finish. I had some that looked like they were made with an angle grinder and sand paper, some were pretty OK. The overall finish of the Isofrane is better, and I also really like the smell of them. I do feel like the price of the strap should reflect the watch you put it on. Putting an Isofrane on a 100 dollar Seiko is overkill. If you can afford the Isofrane and want to have the absolute best, that's your choice.

Sorry, I forgot, I would buy this strap for scuba or snorkel use, particularly snorkeling, the materials and design and looks make it worth some extra $$ but if you don't scube / snorkel I don't see paying the $140

I have several Isofrane and it’s sister brand Tropic straps and love them. If I love a watch, I won’t hesitate to order an Isofrane or Tropic strap. Great review of a great strap.

Anyone know the cheapest place in Canada to buy this strap in Royal Blue? TIA.

I bought one pre-owned and got a good discount. Honestly, I'd say it is worth it. I know it's crazy but you pay a lot of money for good rubber tires (some people do) and this reminds me of that. I like this better than the Tropic strap. I ended up selling Tropic after this.

Yes, absolutely. If you have a posh watch, then surely you want it on a posh strap. Cheers mate 👍🏻 Edit- looks awesome on your Samurai 😍

Hi , I've been watching the channel for a while and really enjoy your content. I've just subscribed. I've got a bunch of Citizen watches and 2 Omegas which I've had cars which are cheaper to run! My Planet Ocean eats its OEM straps and for the time being its been on a ZULUDIVER sailcloth, Bond NATO and a nice gray Crocoldile leather. At around £125 here in the UK the Isofrane is around half the price of Omegas's rubber strap so iris's an attractive option, I'm just not sure I like all those holes!

Great review, I really like your reviews because I collect watches in the same price range

You missed a trick to wear an Alpinist climbing that mountain lol. As for the strap I have been tempted to try Isophrane, it looks a little bulky does it feel that way on wrist?

I actually thought that was a Tudor watch in bronze. That Zelos looks like it was destined to be on that strap!

Looks like a quality product, I think the non tang end diagonal caution looks odd. Can’t get past the price sadly, and it’s a strange choice of product for a budget conscious channel. Interesting but odd none the less

Well thought out design, high quality materials, but the price is more than I am willing to pay.

These days, I wouldn't pay more than $30 for a rubber strap. Something like FKM (Fluorine) rubber strap from Ali can be had as low as $8 while Italian natural rubber from the like of Bonetto is around $20-$30.

I can't find these anywhere in Canada under $200 (plus shipping). I would love a blue one for my San Martin MM300, but I'm going have to keep my eyes open for a good used one.

Head to head with Barton Elite Silicone, please. I think the Barton will destroy it at $20.

When I bought the Omega seamaster 300m 42mm and wanted a rubber strap from Omega they wanted $500 for the strap and buckle

New watch enthusiast here. Still starting off with watches around $100. My only dive watch is thr Casio Duro. The strap would cost nmore than the watch! Excellent review tho! I liked how you paired up the straps with different watches!

That strap with the Samurai seems a great natural fit, geometrically. Not sure if I would like it on a turtle, though.

A really high quality strap is great - but Isofrane are very thick at the buckle where the strap overlaps. Not always the most comfortable, especially at a desk. Crafter Blue, Helm, Deep Blue, Borealis all make cheaper versions that are tapered - it would be cool to see some direct comparisons.

What size wrist do you have? Always worried straps won’t fit my 8 inch wrist.

Way out of my price range. You can now buy nice alternatives from Borealis and Deep Blue for a 1/4 of the cost and style wise it looks pretty much the same and it also holds the watch to your wrist too.

Nice strap but I wish the end was a little thicker or curved to avoid the gap between the case. I really don't like the gap at all. Many people who buy nice watches with a butterfly clasp and have trouble getting a comfortable size will sometimes get frustrated and opt for a nice rubber instead. Sometimes it's for weight saving. That's when these straps come into play. Straps co have models with a curved or thicker end for a bit cheaper.

Insane. That's the cost of the vintage field watch I just bought. And I bought a quality leather strap for it for $13. The Borealis Vulcanized Rubber Strap is comparable and costs $45 only.

Check out Obris morgan, great value, and they have the vanilla smell like the Isofrane.

hey dave how you doing?

This is only for the most hardcore of rubber strap fans. Or people that want rubber for their Rolex or something and feel like it has to be expensive. You can get real rubber straps like this for $10 on AliExpress or ~$30 from a western seller. This at $140 is nothing but excessive

yeah same probleme for g-shock .shop ask for 200 euro for strap gpr-b1000 and 120 € for gwg-1000

I buy watches that I like not so much on price. So if you love a watch why not? My wife bought me a Seiko samurai and I put a 140$ bracelet on it people call me nuts but I love the watch cuz it's something my wife got me so to spend $100 on a rubber strap for something you love I see nothing wrong with it thanks for the review

I'm surprised that they still don't make a strap that accepts the Seiko fat spring bars.

Helm does a clone of these. Really well made and. Comfortable

I could see if it was an exotic leather or something but for a rubber strap it's rediculous. For $140+ sales tax I expect it to come with a happy ending

I guess it would be worth it if you were always at or in the ocean. For that price though they should come with spring bars! :-O I do agree that they do seem to look nicer on Seiko watches.

You’re not spending that kind of money because of the materials used or the way it looks because you can find almost identical for so much less, the money is spent on the brand.

Nice straps. I'd love them at $89.00.

wow ! I'll take 2

Well, $140 is not just north of $100, it is 40% north of $100, so ya, expensive. I like the looks, but the “features” are a stretch. It is marketed as a true dive watch strap, for diving, yet all of the features surround its comfort level on a bare wrist. I get that many wont use it for diving (just like your Seiko you paired it with) but I sometimes have to laugh at the marketing. So no, I would not pay that much for a rubber strap. I have purchased much less expensive rubber straps and they do what I need them to do on my wrist, and for the price, I would rather put a watch that I like on my wrist. But personal choice, and as I said, they are nice looking and I am sure they are solid products that are well made.

I bought a similar strap from Meranom for one of my Vostoks. It cost about 30 dollars. I'll pass on this one.

Sorry but the review felt like an advert sponsored by isoframe.

Dave, I can understand spending $140 on a strap if you've just dropped $1,000 or more on a premium diver (after all, it would just be rude to stick a $20 piece of rubber on it, wouldn't it!🙂). But, for lower priced watches (even those up to say $400-500) I just seems mad, to me!.

Maybe on the zelos. That’s all

Bonetto Cinturini has rubber nato's for 40 bucks that would be a better deal any day of the week

Payed $16 for rubber strap on Ali, then adjusted it to fit in a glide lock rip-off. Total cost: less than $25. Couldn't be happier.

No spring bars... You gotta be kidding...

I am sure it looks and feel great but its way way too much for a replacement strap for me....

Very nice review as always, but I won’t pay $140 for a rubber strap.

Check out Vaer as a sub 500$ filed watch. :) fabulous, American Assembly, American Quartz, great lume, sapphire, 2 straps, pro-environment company, screw down crown..... I can keep going. One of the owners answer the more technical questions. :)

maybe if this were the best watch strap in the world, really impressed me, and if all my watches had the same strap size i would think about getting one of this. but for now i'm going to pass

Get an Uncle Seiko strap, Just as good and over half the price.

Simply put, the price itself is a "feature" of the watch. For pragmatic people, the price has zero justification. People who value nameplates and labels over common sense and value will find the price to be confirmation. of it's "elite product" status.

Decent strap...

The Barton Elite silicone comes with: Quick-release spring bars; Two long-side ends of the strap--a regular length and a shorter length for smaller wrists; Proprietary locking feature so the free end of the strap stays securely in place; Choice of 20 color combinations. And costs only $20. I wouldn't buy the ISO Frame for half its retail price. Good review, nonetheless.

My watch CASIO only 80,but strap isofrane 😅😅😅😅

LOL, NOPES 🤣

The rubber is just FKM. The only rubber that doesn't deteriorate over time, doesn't get sticky, and doesn't attract dust and lint. I do dive and I know the brand. I can say with hand on heart as someone who uses FKM diaphragms in pump design, that these rubber moulded strap cost only a couple of dollars to make. Though I cannot speak for the buckle but I doubt if that's expensive. You will do just as well with FKM straps you can find for $20 to $40.

If you own a 3000 bucks diver it makes sense to me

I would for my $2,000+ watch. For a Seiko 5? Nope.

You should say that "Guys" don't notice the synthetic stink of vanilla after a little while!

On big divers, you need thick strap pins. When the thick pins don't fit the strap, you can lose your watch while diving......gone to the black deep. Sorry this rubber sttap is not worth $100,- Changing a perfect steel bracelet with dive extension on the Samurai for rubber with a thin pin doesn't make sense to me.

Anybody know why the original company went out of business?

Yeah, if you are buying a Rolex or something then you're not gonna bllink at paying this money for a strap so I understand that it seems crazy but there is that market out there.

You can buy this exact strap for 35$

Thanks for your review. With taxes and shipping for Europe, it is not $140, but $176.80 ... So, no for me, even for the best rubber strap on the market. The Borealis seems the best alternative.

The only time I would pay $140 for a rubber strap is if it came on a watch with a W.P.R. of 200+ meters.

is that intro a jojo reference?!?

Fkm rubber/silicone composition for 140$ Ridiculous. Perhaps for a watch bracelet. Then again Not everyone has the disposable income for a Breitling, Rolex, Ap, or Omega..So if you can splurge, Then go ahead and spend on the best! The rest spend accordingly to what makes sense and still is great.

Budget watch channel placing a 140$ rubber watch strap? I don't know Dave... Your channel, your rules I guess. But then there's your audience. Pick.

Square? Really?

No

$140 and they couldn't even get the end of the strap straight!
