Thanks everyone for this superb site, you people are a great help! I am about to order a 16710 (GMT II from 1990s) ,I have to chose either a 2836 or VR3186. I am confused: article about rep movements r/Reptime (from RWI site) says 2836 doesn't have ability to move independent 12hr hand, but on RWI thread "What do you have in 2836", I see pics of GMT watches with 12hr hand in different positions (like the 12hr hand has been moved). Anyway, my main question is: I want long-term reliability of movement, can I trust VR3186 or better to go with 2836 and not have full control of adjustable 12hr hand but workhorse movement that will last ? Hope you guys can educate me with your experience. Thanks a lot.
