I guess we are left with 16800. 16800 are 30.95mm / 16610 are 30.85? So how do they sell those for 16800 and 16610? Sent from my iPad using Tapatalk Pro

Nice watch g, would follow your next step with your mistery case as I have the same:) Sent from my iPad using Tapatalk Pro

Thanks Automatico - great post. Good infos indeed - so not a 1675 then / it has a gasket on the case. Did not think about the 1665. I was working on a few 16610 and bought this case as it was mentioned 16610. Now I did buy a few case backs for my 16610s - including gens and some were mentioned 16610 & 16800 so thought they were the same diameter. Would like to find out if 16800 cases evolved from the earlier models to the 16610 cases then. Did order another case back with 30.95mm thread. Will see. Sent from my iPad using Tapatalk Pro

Thread diameter is 30.95mm might be an early 16800 or a 1675. Will try to order a clear caseback with this diameter. Hope you find out. Sent from my SM-G973F using Tapatalk

Seems gen / thread looks clean only slightly larger than a 16610 caseback. & exactly what i was thinking 1675 or an early 16800..trying to find out the caseback screw thread diameter of those. Sent from my SM-G973F using Tapatalk

I have bought a similar case on the bay, polished serial numbs..was supposed to be 16610 - it is not. 3135 wont fit - it will take 1570/3000 only. I am struggling with the case back as it is larger than a 16610. Someone knows if the 16800 could take a slightly larger case back than the 16610 - thought they were identical?
