Just got my BP 16610 sa3135 , don't bother winding up the movement on picking it up the seconds start sweeping away just like my omega seamaster co axial . And after wearing a full day it has over 30 hours power reserve , also it's 2 sec slow a day . Will keep it boxed till I manage to drive to the watch maker 45 miles away . I don't wind it and have found two sources to buy sa so will buy a spare for parts. Just hope once oiling auto wind it stays ok .
I think it is a great movement and all this 50 + winds never had to do that with any auto watches . Also wouldn't bother with Putin on a winder to wear the hell out of the gears.
I bought a blue one and the "Swiss Made" is missing at the 6 hour marker but other than that its perfect. Also the glow in the dark stick markers to not have the white gold border around them like the original.
I'm after all the major dimensions (especially stem height) for the genuine cal 8500. I have a planet ocean 8500 NOS case (reference 220.127.116.11.01.002) and the earlier dial and hands to fit the cal 2500. I'm going to make a Frankenwatch with a omega 1120 or 2500 omega coaxial movement in the later 8500 case. So stem height I think is my (main) issue
Any help much appreciated!
