And when you’re not diving, it’s handy to use to remind you when it’s time to turn the chicken on the grill. 😆👍

The only time I've used dive bezels to time something submerged in water is when I boil eggs 😆

this is a much better explanation than the "so you don't run out of air" that you usually get from other sources. awesome stuff as always Marc

Never been diving, and first time I ever looked this up. I always assumed it was way more complicated than that! 🤣 Love the alternate plans for flipping food, or laundry duty!!

Thx for the deep dive ! I'm decompressing now

Hi! I thought it might interest you to know another way you can use your bezel to plan your dives that my mentor taught me. Before your dive, you can check the no-decompression-limits of the depth to which you're descending with the nitrogen tables. Right before your descent, you can then move the bezel so that the bezel's arrow would show you the point at which you'd be crossing your NDL. For example, for an 18-meter non-repetitive dive, decompression would become mandatory upon the 51st minute. If you're starting the descent at 10:05, you would move the arrow to the 56th minute on your watch. This way the arrow plainly shows you your limits, and helps show you how much you've exceeded your NDL if ever that would happen - which is supposedly why the Seiko Pepsi watch's first twenty minute degrees are marked red. I myself have never dived with just a dive watch, but if the computer fails during the dive you'll at least have a clear track of your NDL :)

To get a second time zone, just múltiply the first digit in each Minute mark and eliminate the cero. Example 30 X 2 = 60, eliminate 0 then you get 6 hours. 40 X 2 = 80, eliminate 0 and will be 8 hours., and so on. Move the bizel to find time zone needed. Now you can use it as gmt keep your diver watch and save money.

Nice description. Plan the dive, dive the plan. Know your dive site, you'll know the maximum depth, set the bezel accordingly. I've always used a (Suunto) dive computer, but backup-anything is always a Good Idea when you're not surrounded by lots of lovely air.

I love using my bezel to track another time zone, as a compass, to count up or down from hours, minutes, and seconds, and it's fun to click when I'm bored lol.

Great video, but you're using the bezel wrong. If you set the arrow on the bezel to the minute marker when you start your dive, hen all you're doing is tracking elapsed time, and in order to know when to start your ascent, you have to do math to stay on track (bottom time - elapsed time). Instead, you set the arrow of the bezel an amount of minutes ahead that is equal to your bottom time. That way, all you have to remember is that when the minute hand reaches the arrow, it's time to ascend. At that point, your bezel is automatically timing the ascent. Of course, few people dive flat profiles now that we have computers, and even fewer dive from a watch alone.

That was very interesting. And oof! That picture 😳 😂. Congratulations on receiving your PADI certification.

Man! This guy knows and loves watches. Thanks for sharing your knowledge

Thanks Marc for this explanation! Very interesting. Makes me wanna rotate my SKX bezel again for some more desk diving ;-)

Marc, the bezel can also be used to time different rates of ascent when using decompression stops, as well as the length of the deco stops.

I had bought my first watch (a SEIKO 4R36), and I had no idea how to use this until now, thank you for the good video. You narrate very well!

Finally! Somebody who explains it right! Thank you from a PADI buddy!

Congrats on the PADI certification Marc👌! And thanks for the free bezel lesson

Excellent topic and instruction. I got NAUI certified back in the 1990s and they never discussed dive watches and how to use the bezels. It was purely the tables and the dive computers. Of course, I'd never wear any watch over my thick neoprene dive suit and risk losing or damaging it. Might consider wearing a watch in the warm waters of the Caribbean... Thanks, Marc!

I didn’t know what is a rotating bezel for and your explanations enlighten me . Thank you. However, I am not a big fan of scuba diving . The only thing that really fascinated me were divers watches. Lesson learnt and understood 😀

Congrats on your PADI cert and a great video

I use it to remember when I fed my dog. He farts alot if I feed him one big meal, so I split it up in smaller meals every 6 hours. :p

Just found these watch and learn lessons. Well done.

Before dive verify pressure on tanks adequate for planned dive time. Reference chart for decompression stops on ascent if required. Just before entering water set bezel to max dive time less ascent and reserve. The graduations after the triangle on the bezel are for checking emergency reserve when max dive time is exceeded. This way you dont have to calculate how long you've been down. I have never used it any other way. Very simple and very easy never go past the triangle on a dive.

Good on ya for this "I stand corrected" post. I got my open-water cert back in 1971!

Good video. When I learned to dive, instead of remembering it, I was taught to mark the bottom time by moving the bezel to that minute marker. Of course that was over three decades ago.

Congratulations on your diving cert. (years ago lol) I'm the more common PADI wearer who never gets below 10 feet (but was ocean lifeguard certified in my youth). Question for everyone: Would you take a non-Seiko watch to your Seiko dealer for repairs/service? (Specifically a 1982 Tag Heuer for a new bezel, sapphire crystal replacement and cleaning).

Great video Mark. Many thanks fella

I am late to congratulate you. Welcome to the dive community. I will be getting a watch from you one day

Glad to see you revisit this. Welcome to the OW world. ~B

THANK YOU for the clear and straightforward explanation for a layman. CHEERS!

I just watched your older bezel watch N learn episode yesterday.

always thought it was to determine how much time is left, good explaination

good job on explaining the bezel on dive watches ✌️ I too use them as backup for recreational dives 👌🏽 congrats on getting OW certified 🎉

Just received my 007 from you. Love it. Thanks.

It's a one hour oven timer for me ! Thanks Mark for the video

Wow. Thanks for this. Never really understood it. This is great explaination.

Congrats on Padi Open Water certification! I felt so happy when I got mine in Egypt 🇪🇬

i dig your surf colors on Islander watches. bold and beautiful

Finally I know how to use these!!! I’m gonna be using my Tissot Seastar to time my employees lunch breaks 😂😭😭😭

Thanks for the video, Mark. That's an interesting chart. Everything you said I was going to type you covered about divers using a computer and backup watch. I think most people who buy diver watches they buy for everyday use.

That's a great instructive video

Congratulations, Marc!

Thanks, never knew this! ‘Every day’s a school day’ 👍

i love dive watches and now i can confidently know how to use it (as a non diver) lol but i love the easy explanation so anyone can understand

Well I’m no diver, but that’s fascinating. I could see myself using the dive bezel for lots of different things. Thanks for the video!

this is great stuff man ! Thanks for going over it !

Thank you for the video. Keep up the good work.

I love dive watches! I've never dived in my life...I can't even swim!

Just bought my first watch with the rotating bezel function and had absolutely no idea what it was for mind spins both ways but with some resistance and I can't hear the click but thank you for the video

Great Info

As a qualified BSAC sports diver (advanced open water/rescue diver PADI equivalent) i’ve found a dive watch handy for timing other peoples dives from the boat (to know if they are overdue) and the ticking seconds useful for the last minute of ascent after a safety stop from 18 feet (6metres) to the surface. Most of the rest is done on a computer as the computer dynamically recalculates deco time every few seconds. When abroad, you’ll often do deco wile swimming along a scenic reef at a shallower depth to extend dive time, this hard to do with a watch as you can only do a max depth max time calculation at the start. Still, every diver needs the time for other reasons (eg tide times ) and your generally on a wet boat so there will always be a need for a water proof watch one unless you get a watch sized computer but they are digital and look crap (pah!) :)

It let's me know how long I've been jogging 😎👍

Congrats on the cert! I often thought about it...but 🦈🦈🦈. Watch out! I think we are now on their food chain.

great clear explination, thanks

I'm so excited to recieve my SKX009J which I ordered from your shop. Thanks for all the great tutorials. I'd like to be able to use my watch properly, so this is perfect!

My relatively extensive dive experience was long ago when I lived on Grand Cayman for two years. Dive computers weren't invented; I used a digital casio but It was even pre g shock!

Great video!

So a Rolex Submariner doesn't have ISO 6425 specs, because their bezels don't have 1 minute increments?

I didn't know why I watched this video because I don't even let myself get close to a swimming pool let alone go diving. All I knew was it was a video from Marc, therefore I have to watch it. It's ironic that diver watches are my favorite kind of watches.

you nailed it.

Fancy lighting looks fancy :)

Any updates about insert for Orient Triton ?

So why use a dive watch when you can use a chronograph? Don't they have the same function?

Skx is visually a masterpiece.

Cool stuff Marc, congratulations!

Interesting. I'm a cook myself, and I tend to be scatter brained in the kitchen. I use it to remind me when I put something in to bake etc. I also use it to remind me of appt times etc.

Congrats!

This isn't really the correct way to use one. Better to use it as a countdown timer not count up. If you plan to dive a 37 minute dive then point the minute hand to 23 at the start of the dive. That way the bezel counts DOWN to zero. Otherwise you are trying to remember a different number on every dive, which is not foolproof. This also explains why the pepsi bezel is colored how it is. Red is the zero or hard stop marker for NDL.

Good discourse of your experiance. This was interesting and thanks.

I wish you could've used a citizen promaster BN0150-28E so you can also explain what the latter's and numbers on the side of the rubber strap mean?

Nearly at 100k 😎😎😎

Great video...thks !!!

It's correct that divers use computers today. If you want a backup diving watch, buy a Pyle snorkeling/dive watch PSNKW30O (amazon, walmart). Diver wristwatches are for telling time these days but they're still great.

Been using multi compartment dive comps since the mid '90s. I'll wear a dive watch, and carry the tables in a BC pocket, but they're only there in case the comp goes into timer/depth gauge mode, or just quits. They are handy for doing surface intervals, but most dive computers will let you do that plan too.

Thanks for the info.

Super interesting! Many thanks for explaining. 👊

I find the bezel to be useful. For instance, if my personal best for a certain activity is 3 minutes I can use it to keep track of improvements. 🤪

I went on an advanced dive in South Florida a few weeks ago. The crew did not allow me to use a dive watch alone. I was required to use a dive computer.

My Mares Smart Air has the pressure gauge transmitter. Pretty cool setup, but maybe not the most friendly. If you measure in bars the pressure indication is clearer. I’ll be very interested to see what you end up with after you research it and talk to your dive buddies.

I have quite some dive certificates (I am a dive master, 3 star CMAS license, with advanced nitrox certification) and we never ever discussed how to use a bezel on a dive watch. I though off course know how to use all dive tables, but normally I use an advanced dive computer (a Suunto). I also would never use an expensive watch as a backup. I have the cheapest dive watch you can get as backup in case of decompression (deco) dives. In case of no deco dive, I wouldnt take an additional watch. In such a case I can simply rise without stop and there is always a buddy as backup. And a dive computer has off course a system to monitor battery health and I never dive without good battery health.

So what’s with the Pepsi color using red in the lowers numbers makes it seem like you’d be running out of time until you realize it would be counting up not down so what gives?

Great video 👍I'm no diver, but I use my 'perfect rice' bezel all the time 😁

Thank you for the vid!

Such a great video as always!! I took my Orient Diver into a Ocean...front view hot tub in Santa Cruz 🤣 true story

Nice vid. 👍🏻

Thanks Mark!

Is it the same for desk diving?

Now I know.thanks for that.i can speak with knowledge now.one question,I was told that the Pepsi bezel has a red section of 20min because a typical air tank contains that much air supply...Is thst not true?

Great video for us who actually use a dive watch for its intended purpose as a back up to dive computers (yes plural). #TwoIsOne #OneIsNone #MasterDiver #PADI #NAUI

Great photo on your certification. Reminds me of my drivers license. lol

Well I definitely learned something today. Thanks, Marc!

The unidirectional thing totally makes sense now

Had to laugh when I saw that the black turtle’s dual time bezel on the poster is misaligned. 😂

1:20 😂, we love you Marc!

Welcome to a whole new world.

Mark, I think I speak for us all when I say thanks for the "Watch and Learn" videos you do. I have learned a lot. One big question I have about the whole dive bezel use is: If the bezel is used to measure elapsed time what gives with the first 15-20 minutes that is sometimes highlighted with red or orange or some color that provides clear legible contrast? If you had a 38 minute bottom time dive what use is the red on a 009? I have read that the typical bottom time dive for recreational diving is 15-20 mins. at a depth of 30 meters. Could that be the reason? to measure that recreational dive time? Would then the diver not be susceptible to pressure sickness because he/she was not not down long enough? Please help me understand. Thanks

Love Turks! It’s our favourite island/beach place in the Caribbean!

But what if the dive leader wasn't there on your first dive? That bezel was also used to ensure you didn't go over your NDL on that dive. The dive would be planned with tables, maximum depth, and the time you could stay there. The bezel was set at the beginning of the dive so you knew when to come up as per your plan. Nobody really does this now because it is so inflexible, particularly if you don't stay at your max depth. Computers can work out your NDL on the fly. It is still good practice to be able use tables, and to know the NDL for your max depth, but many people do just rely on their computer nowadays (rightly or wrongly). I still use a dive watch, and find it indispensable when teaching. The majority of dive computers do not show seconds because minutes are as fine scale as you need even for technical diving. However, during several skills in training, as you may recall, timing to the second is necessary. Watches are much handier for this purpose than stopwatches, I find. Other than that dive watches are indeed completely redundant underwater, save for looking retro cool. 😊 On the subject of retro chic underwater, please Marc, if I can give you any advice as a new diver, do not buy a massive dive knife and strap it to the outside of your lower leg!

I can the new Rolex Grill Master watch coming out. Far more useful than a dive watch.

I use my bezel multiple times daily. Perfect for woodworking...
