Interesting. Had no idea the 2836 was not ETA through and through.It should be noted here that ETA does not make a GMT version of the 2836-2. These are Hangzhou 6306s, modified to run an independent 24 hour hand.
The Chinese GMT adjustment function is a smooth sweeping 24 hour hand, it does not "click."
With the GMT "2836" the entire movement is a Hangzhou, at least from what I've seen.Interesting. Had no idea the 2836 was not ETA through and through.
If the 2893 24 hour hand is properly set up to be in perfect synch with the hour hand then it's a wonderful convenience. It would seem nonsensical to prefer the 2836 because it solves the problem of an incorrectly synched 2893...
On the face of it, the 2893, being all ETA, would seem the "better" movement, but not knowing how extensive and crucial the Hangzhou GMT modification is to the reliability of the movement I have no way to draw other conclusions or rank one over the other.
If that's true, that the entire (or large portion of) the 2836 movement is Hangzhou, why would ETA allow manufacturers to call it an ETA 2836? (Just checked a couple boutique websites, where it's called ETA 2836. Haven't checked the big boys.) :-sWith the GMT "2836" the entire movement is a Hangzhou, at least from what I've seen.
The Chinese GMTs are preferred by some simply on the price and availability.
The Hangzhou 6306 is a direct copy of an ETA 2836-2 made entirely at the Hangzhou Watch Company's facilities in the Yuhang District of Hangzhou. If you don't know where to look closely, the two are identical.If that's true, that the entire (or large portion of) the 2836 movement is Hangzhou, why would ETA allow manufacturers to call it an ETA 2836?

I didn't realize that anyone else was doing the 2836 GMT mod....Would like to share with you my experience with 2836 GMT and ETA 2893 GMT.
Both movements are Swiss Made. However as mentioned ETA does not make an ETA 2836 GMT. What it happens is that some companies in Switzerland do modifications to the 2836 movement so that it can accommodate a 24 hour hand. One of those examples is Leschot company.
At time we were starting production of the Prometheus Ocean Diver GMT we were inclined to use the ETA 2836 GMT as it was more readily available than the 2893 .
During test phase we saw that modification of 2836 movement would turn it less reliable at time of maintenance as would be harder for buyers to find spare parts in future.
Final decision was a no brainer. We decided to stick to more universal standards and use ETA 2893 as this will ensure all buyers to find spare parts in future and get watch maintained by any reputable watchmaker.
Attached tech designs of ETA 2836 GMT which many never seen before.
If I had to guess, it's that the 24 hour hand taps into the indicator and quickset functionality associated with the Day of Week complication on the ETA 2836. If you intend to use your GMT complication regularly, I would strongly suggest getting the a watch based on the ETA 2893 instead, as I don't think any legitimate manufacturer will implement the GMT complication using this hack on the ETA 2836.Hi
Bring this tread to life again. I have been looking at GMT watches. All I found on that page, selling replicas, has the 2836 movement, with both date and 24h hand.
How is that done then?
Is there a difference in how the GMT complication is implemented on the Explorer II and the Panerai 441?Yup,have to agree that 2893 movt is a bit less practical for travelling,recently I was travelling twice with 2 different GMT watches,one is Pam 23 (2893 based),the other one is Pam 441 (P9001,12 hrs GMT,quickset on main hour hand)
From that experience,I prefer the quickset on a main hour hand better than 2893 where I have to set the main hour and the GMT hands separately
In my next travel,I'm tempted to bring my exp II to check the practicality of true 24 hrs gmt coupled with quick set main hour hand
Okay, so it's like the Jaeger-LeCoultre Master Hometime or Patek Philippe Travel Time. I actually like that as you can hide the second time zone when you're at home, as you mentioned above.Well,the P9001 have 12 hrs GMT hand (i think the other in house Pams are also using 12 hrs GMT,with am/pm indicator subdial),so while i'm local,I can actually hide the GMT hand behind the main hour hand
On exp 2 (and maybe GMT master II since I've never played with one) the GMT hand is 24 hrs,so I cannot hide the GMT hand under the main hour hand
I'm pretty sure the modified ETA 2836 is only with the quickset GMT hand. If you want a lower priced quickset hour hand, check the Alpina GMT line. Or go quartz.I'm still in my quest to find a GMT I want to cherish for a long time. From what I understand, with the exception of some in-house Rolex, Omega, and Seiko movements, almost all GMT movements with a quick-set* function have this on the GMT hand and NOT the hour hand. Please correct me if I am wrong but it appears that the ETA 2893-2 has a quick-set GMT (is it common to drop the 2 because the first version isn't made anymore or some other reason?).
Can anyone confirm if the modified ETA 2836s have the quick-set functionality and if it is on the GMT hand (most likely if it's there) or the hour hand (I wish and hope and dream)?
Also according to their website Bernhardt uses a modified ETA 2836 in their Globemaster II (click technical specs at the bottom). I have heard that this features a quick-set GMT but have never held one to confirm it myself. Anyone care to speak to this?
*quick-set meaning that you can turn the crown and have the quick set hand jump one hour while maintaining the current minute offset as opposed to an independent hand which simply moves smoothly around the dial
I love the Alpina GMTs with the exception of the 36 mark bezel (assuming for 360˚ but I am not sure how one would use this). Do you have any quartz recommendations? I'd appreciate them as I haven't discovered any with the quick set hour and GMT bezel.I'm pretty sure the modified ETA 2836 is only with the quickset GMT hand. If you want a lower priced quickset hour hand, check the Alpina GMT line. Or go quartz.
