The problem here is the Powermatic 80 can not be regulated , it is factory set and can only be fixed at the Tissot Service Center by replacing the balance wheel assy. The standard caliber may be fixed by any watchmaker for a regular fee.

80 hr power reserve, extended time before servicing, and more accurate. The powermatic is a no brainer.

Thanks for this vid. Predicting the classic to climb in value is dead on too. Get one now if you think you want it.

You give the most accurate reviews Bruce. Well done. Love hamiltons. Thinking about getting the khaki field though.

I wish they would make a 2.5Hz option, for ultimate power reserve, and so that the second hand is hitting every sub-second register accurately. It's also historically a popular beat frequency.

Wonderful video and an excellent comparison

Awesome comparison, thank you.

Awesome, didnt even know two versions existed. Learnt something new today. Thanks man

My powermatic 80 in a Tissot is +2s a day. I couldn't be happier with it.

Excellent comparison. I enjoy how you research technical details thoroughly. Hard to choose between those two.

I wanted answers. I got them. Thank you!

Thank you for this, as I have a Khaki Field King and didn't know that there where two versions. I'm happy to know that I have the Powermatic version, as this should require servicing at longer intervals, due to its lower beat rate.

Love my H-40 Powermatic, it's the most accurate automatic I own. The relative lack of smoothness to the second hand never has bothered me. Btw, as of 2020, the rotor has been slightly redesigned. Hamilton has changed "H" cutout to the more stylized, retro logo, and I personally think it looks much cooler now than the plain H shown in this video.

Bruce, u're a saviour. I'm torn between Tissot gentleman powermatic 80 and Tissot visodate heritage automatic, and you gave the answer. Since i rotate wearing my watches on daily basis, the power reserve isn't my priority coz it might take weeks before i wear one again. Thus, the smooth sweeping second hand is my preference. Thanks Bruce.

thanks for this comparison. Being relatively new to buying watches of any consequence, this was an issue that came up during my search for a watch. I was persuaded to buy a watch with a higher beat rate; in this case, it was the ETA 2824-2. Being a second or 2 more accurate and a larger power reserve is not really a big deal to me... having a smoother second hand is. I guess it all comes down to personal preference, but the classic movement appeals to me more. Great job as always, Bruce.

My Tissot Chemin de Tourelles with powermatic 80 gets -1 sec/day out of the box. impressed with the accuracy for the price.

Took receipt of my Powermatic 80 version today. PURE CLASS

Excellent review. The 80 hrs reserve on the powermatic is a very good upgrade.

I like the smooth sweep too. I don’t own a Hamilton, but the Powermatic 80 in my lovely new Certina DS Action 38mm diver continues to give me less than a one-second gain every day, which I REALLY like!

Great comparison. I'll take the Powermatic 80 in this case. I've owned watches with the 28xx-2 that ran great , but my little Tissot with the Powermatic is my most accurate watch to date. I have enough watches that the 80hr power reserve is also nice to have. Again, great comparison.

Awesome video Bruce!

I just now gave my husband the Powermatic 80. He's a back country guide in the high mountains here in Colorado. The extended power reserve is a plus for him. Due to the nature of the adventures he leads in the mountains, adventures which would not suit wearing a watch, it's wonderful the watch has the 80-hour power reserve out in the wild.

I love the intro, it sounds epic lol

Thank you for the video! I just bought 2nd hand the classic one👍

I have the new Hamilton field automatic with the H10 movement . I could not find the older one with the ETA 2824-2 . Still i am very happy with the one I have . ( I got 16 % off at a authorized dealer ) Good video thanks .

Thanks for the video thumbs up

Good info . I have the new one . I love it . Thanks .

Great Sharing .. I love my Hamilton Khaki Air Race with ETA C7.111 with Powermatic. I buy pre used with great price 1400 Malaysia Ringgit with Great condition ... What a wonderful watch.

Great and informative comparison video.. thank you.

This is so helpful! Many thanks Bruce.

Good review. Subscribed. Also, I could be wrong but it appears the size of the crowns are also different.

I have a new Hamilton field automatic 38 with the H10 movement. I am vwryj happy with it .

The H-10 Powermatic movement in my Khaki Field Auto runs at +4 a day. Owning so many Seiko watches with 21,600 BPH movements (7S26, 4R36, 6R15), I don't find the 3 Hz movement in the Hamilton to be that noticeable. For me, it's all about the watch itself and these Hamiltons are quite attractive.

This is one of the best, if not, the best Hamilton watch in my opinion. Looks really good on the leather though.

The ETA's tuned by the brands that use them give a satisfactory result.

Man I like you camera work, always make the watch look more disirable than it actually is.

I would prefer the classic ETA movement. I love the smooth moving second hand on classic ETA movement.

With a Day/Date compilation power reserve is a major plus unless it’s a daily wear. Resetting the Day/Date doesn’t take long but could be mitigated with a longer static shelf life. The seconds hand smoother sweep is a very minor aesthetic thing which is barely noticeable even in macro. The lack of anti reflective coating is a minus, surely a decent movement warrants such an inexpensive upgrade to the sapphire glare. Overall you can’t go far wrong - is it true that a lower beat frequency means longer service intervals? I guess there’s less wear and tear going on at 3Hz in the Powermatic. Overall both decent watches but I’d opt for the longer shelf life as I tend to rotate my modest collection. Both give decent accuracy as you’d expect from ETA. I have a low end Miyota movement in a beater Rotary watch which gives about +7s/day which isn’t bad for a cheap watch which I bought at 55% discount. Check out the Rotary Cambridge folks, I think this is excellent bang for the buck.

Thanks for the cool video Bruce. How about the price difference? To big or negligible?

I have to say that "Swiss Made" on the dial means far less after the MoonSwatch than it did before. For me hi-beat is going to win out every time. Power reserve having no bearing on anything much. I recently had a problem with my left elbow and struggled with a bone infection for several months, the upshot of this was that for the first time I realised my lack of movement wasn't inputting enough energy to wind the movement, at the same time I realised that for a regular person 38 hour reserve is adequate. I'm quite happy to wind and set whichever watch I choose for the day. I guess if you have 2 or 3 pieces it's more of a concern.

Great review! Is in this time possible to buy "old" version ? Thank you for your reply.

Well done sir!

awwww, great content Bruce. I just pulled the trigger on the Hamilton 646150 which is the pilot "Cooper" you once reviewed as well, and almost returned it cause of the new rotor BS. I also noticed that the H has been cut out different logo, why??

One way to think of the new Hamilton H series (H-40), is that, being free-sprung, it is like a Rolex with it's Microstella adjustment, and other luxury level timepieces, (Patek)-The Hamilton being similarly adjustable, not un-adjustable as some contend.

Classic ETA all the way. The smooth sweep is where it's at.

Great review 👍

i also noticed the application of the idices on the powermatic are much cleaner and crisper.

Thanks for video, owned both. Powermatic is my choice.

Bruce, another nice video, however I think we deserve to have a clear overall recommendations on which one to pick between the two, that's why we are here, at least giving us ur personal preferences, this is what comparison vid all about, do not miss understand my comment as I gave LIKE :)

My Powermatic Khaki King is +/- 1 seconds a day when worn. It's amazing. I like the 80 hours power reserve but i almost wear it every day.

Hamilton cannot give a damn to give anti-glare coatings to those sapphires ...

great video. why do both watches have H644550 on case back? also, my powermatic has a different, more stylized "H" cutout on the movement?

Never decide before having a powermatic movement on any brand, i had a tissot couturier with powermatic 80, at first days of owning the watch that 80 hours looked like a magic to me but when you try to use it once in 2 days nothing makes it more special than a classic eta then you and your lower beating remain, just like having a seiko 5! Friends, visibility is important, what you see is important! so stay with your classic eta movement and be happy, i am happy as i have sold my boring powermatic 80 ;)

I don't know if I should order the one with the silver dial or this one. The only problem with the silver dial is that I can't find one with the steel bracelet.

i got a khaki field with the powermatic 80, its super dead accurate out of the box, i do miss the hi beat, but thats what other watches are for !

Classic with the 4x bpm.

Bruce, there's another advantage to the new powermatic 80. With the lower beat rate it will extend the service interval that one would expect which will reduce the overall cost of ownership. If you're looking for a sweeping second hand go to a Bulova precisionist where their movement is accurate to within ten seconds a year.

I'm surprised so many people in the comments care only about the power reserve. I own a 2824 Khaki and returned a Powermatic Khaki. I love the sweep hand on the 2824 and I like that I can regulate the time myself. An 80 power reserve is not a big deal because I either wear a watch every day, or a rotate my watches enough that a Powermatic would be run down the next time I'd wear it anyway. 2824-2 for the win!

Where did you buy the Kind with the older ETA movement?

I really like this watch. Hmm! I gotta stop myself. Again. Thanks for making it harder haha 😂

My Hamilton has the H10 movement, but the beat error is quite poor. Can this be adjusted?

Although the sweep of the seconds hand is nicer on the ETA movement with it's 4Hz frequency, it's also more prone to wear in comparison to the 3Hz frequency of the Powermatic 80. Therefore the ETA is more likely to cost more in terms of servicing.

I brought a Glycine 48 mm KMU automatic, that I liked alittle, big exhibition case back , with a Sellita 200 movement. It ran great, on a meter, just 1 or two seconds off a day on a meter, when it was wound up. Winding down it would run fast. It just was a bit big on my wrist, and the lume was a bit disappointing. Only for 350.00. A lot of watch for the money. I sent it back and picked up the Hamilton Khaki aviation 46mm. It’s a bit of a disappointment also for 600 .OO . the lume is about the same....the movement is well.....? It’s like a Seiko but with a longer power reserve....if its accurate, great, hasn’t shown signs of that ,it’s was running spot on , on the wrist and set, off the wrist it’s running 5+ seconds fast. I really liked the face on this watch. I was going to return it immediately, but I figured it’s a sort of “dumbed down” ETA 2824, that’s how they get the big power reserve. The actual movement is small compared to the watch. I figure that because the smaller movement can handle more torque, again because of its power reserve. I don’t know if I can return it to Jomashop. If this information had been availible, when I was researching the watch ,I would have had good information on which to buy the watch. There is just a lot of people on the net doing watch reviews , who don’t really know enough about watches....

I am a watch collector with considerably more than 100 watches in my collection, is 80 hours reserve going to enough? dont think so, what I do appreciate is the more even sweep and the adjustability of the older movement and potentially greater accuracy. When it comes to servicing the 80 hour reserve watches good luck finding a local watchmaker who will be happy to do them and in 50 years time when all my classic vintage watches are ticking along fine where will the 80 hour unadjustable version be?......................

My Hamilton with the Powermatic 80 movement is dead on accurate without any deviation from the atomic clock if worn everyday. The power reserve is great and seems like an upgrade from the old movement. But I do miss the smoother sweep of the 4 Hz beating.

My Tissot Seastar 1000 2nd gen is at 35 secs accuracy. Think I need to bring to my AD for calibration.

Either are great. I have the powermatic version. I like the accuracy, the longer power reserve and the noticeable beat of the second hand reinforces the mechanical nature of the movement. I like that but go with either as they are great watches.

Love that review so informative you and random rob my favourite reviewers. Where would you recommend buying the H version from in USA we can't get them in Australia.

Hello sir, since on the dail doesn't says "swiss made" should i be worry that the watch isn't completely swiss made. Swiss movement but cased in china kinda thing? Thanks

I have the H-40 Khaki. It's amazing. Not to be confused with Tissot powermatic 80. That regulator used a silicone hair spring. Hamilton does not, there is a difference in that the regulating operation system on the Tissot powermatic is that it's done internally H-40 is Hamilton's power reserve system.

Hey Bruce wondering if you would buy this watch at a 20% discount? Reason I am asking is I like to buy a watch when I go on vacation. I know joma sells these at 375 but the discount at an A.D. would be about 20% . Whats your thoughts?

Where did you get your 38-hour reserve version?

Bruce, you stated that you don't have many automatic watches. Does that mean you prefer quartz or other? Would you please elaborate a bit on that? Thanks!

I can't decide between the day and date H64615135 or this one. Which would you pick?

Thanks for the clarification. Do you happen to know if the Powermatic is still an ETA make or is it SELLITA? How do you adjust the time in the Powermatic? Thanks again

I have the same watch, the one with the 80 hours power reserve. They "H" that's above the word Hamilton on the rotor on mine is a different looking letter "H" than the one in your video. Any ideas as to why this might be? 🤔

After 3 years do we have info about H-50? How is it working? Is it durable and withotu any problems? I would be very interested to know as I would be interested in getting one. How often it should need service? Can a simple watchmaker do it or it must be sent to Hamilton?

Do costs to maintain and repair differ between the Two movements?

Sorry I'm new to watches. Are there any other Hamilton Pilot day date watches with that same classic ETA? I can't seem to find any and prefer that smoother sweep.

If the movement is guaranteed to be less than +5s it would be a go for me with the 80h of PR. If not I like to regulate my watches myself. But it would be much more tricky to do so on the Powermatic 80. 🤔

The lower 21600 beat rate of the Powermatic is the same rate used by the Royal Oak and a ton of Patek watches. It’s clearly not a big deal and the longer power reserve and less wear and tear more than outweigh the slightly aesthetic advantage of a smoother sweep

From the video, the printing on the dial seems sharper on the Powermatic.

Are these differernces found on the Jazzmaster as well?

Hello, wich grade are movements ? Are chronometer certified ? Regards

Nice comparison. What is the diameter of the case?

Good video! 💯 I think that the powermatic 80 version is better.

I have the hamilton watch pilot day with 2834-2 in 2020. +4-5 sec / 24 hrs

Very cool👍

Very Good

I prefer the classic 2824-2

Correction, again. You state that you really mean it's a 2836-2. However later in the video one can clearly see 2834-2 stamped on the caseback.

28,800 FTW !! If you are worried about it's 40hr power reserve (and can't last over the weekend), but a watch winder off eBay for 25bucks. The movement is way better on the classics. It's a fact.

Hello, I´ve recently purchased a Certina watch with the powermatic 80 caliber and after running for two weeks, all the day in my wrist and resting at night face up, I´m having an accuracy of +24 to +38 seconds a day. Is it considered normal? (Certina says -5 to +25 is normal). Should I wait some time until it is stabilized? Thank you.

Any difference in shock absorption?

Merci beaucoup l'Ami

Hi Bruce is powermatic a good movement? I know ETa is pretty robust. Is powermatic equally good?

Are the powermatic 80 is the same movement mido calibre 80?

if you like a smooth sweep you should get a GS Spring Drive !

does the older version have any more water resistance

The classic for me.
