I like the ETA powered breitlings more than the Breitling B01 movement for example. I do like Rolex movements more than ETA and certain ETA calibers better than others though, and I think that's a fair opinion.

Here's where I do pose a bit of a challenge. The OP was a question about which is better:

7750 vs 2892: I still believe that the 2892 with modules > 7750.

Why:

I like the 2892 winding system better, its quieter and smoother if you will in operation versus 7750s which can get loud. The 7750 winds in only one direction so it can wobble a bit. I've regulated a 7750 to dead-on, never been able to do that with other movements. I find that the chrono mechanism especially hour totalizer is a bit fragile in the 7750, the fake 7750s really don't work. 2892 just feels more robust refined and substantive in the operation. Sort of like the 2824 it just more or less works.

Rolex vs ETA: I still believe that the Rolex >> ETA.

Why:

I like the microstella adjustment system that makes the movement more uniformly circular ( http://people.timezone.com/library/c...28417314218750 ) and more difficult to knock out of regulation vs the eta fine adjustment. I like the quicksets, it is very easy to mistakenly set the time or date during a "danger" period. I like the variance better too. That doesn't mean you can't get a 7750 to be dead on, it might take a bit more work to keep it there though, imo.


I own and enjoy all the movements discussed above.



I'll check out the unitas and as an aside I agree the old venus chronograph movements are very cool.

What I cannot understand with most high end brands is why they don't use alloys like invar or similar when making there movements.Today even Rolex, JLC, and even Patek still make there now very expensive movements out of cheap brass.But the ETA 2892 yes its a fantastic movement and very accurate when regulated correctly. And even some of todays Pateks while being very pretty to look at,and looking pretty does not mean its a accurate movement. And in the real world does not match the 2892 for accuracy and are far more delicate as far as long term reliability.But over all for a 3 dial type chronograph I would choose the 7750 range over the 2892 plus module. The 10mm balance wheel is the same size as the cal 3135 on the 7750 and if regulated correctly very accurate.Yes the 7750 only winds one way and yes the now famous wobble can be felt on the wrist.But over all the 7750 range with all its quirks has a well proven track record like the 2892. And is in the top 10 of all chronograph movements made and is highly regarded in the watch world today.

I have had many 7750 chronographs. Only draw back right now is Bob R wanted 950 for service on my UG
