I’m not familiar with the BP sub. That sounds like a lot of work. I’d have to see the rehaut. Most rep 16610’s aren’t deep enough unless you get an MBW or TC. This JF 16610 was actually about right. The old noobmariner would be perfect but I haven’t seen one in years. Lug holes are a necessity for a 16800.
You can can see the rehaut dept diff between my JF 16800 and my MBW 16610. The MBW rehaut is correct 16610 depth and you can see how shallow the JF case is in comparison.
JF shallow 16610 case. This is the v1 with shaved rehaut engraving.
Incorrect for 16610 but close to the 16800 case
MBW correct 16610 depth
Damn!! Oldschool MBW and noobmariner. But from my memory, didn't some MBW and noobmariner had a wokky rehaut?
Your JF with low rehaut height must be the JF V2 case? (i.e. JF 16610 LN with rehaut engraving and corrected wokky-ness). I had the JF V2 case before and I was going to use that case for a 16800 build (i even had adrian drill lug holes into the case). But I ran into a problem: the JF V2 case doesn't take gen gasket because the gen gasket causes the crystal to hit the seocnds hand. It turns out the stock JF V2 gasket is 2.7mm tall (to compensate for the lower rehaut height) - at least that happened in my case.
Nevertheless, I wished i could have started the rep game earlier (i.e. late 2000s and early 2010s) when gen rolex parts were much cheaper. Back then, you guys could afford to chop off the dial feet on a gen 1680 and 1675 dial because they weren't exactly that sought after lol.
