That's a mystery, isn't it?
The whole WM9 v1 thing I mean... those watches used to have the same green back sticker as the very old "TW Best" models. It'd be interesting to know where PT can source them.
PT's v1 is an amazing Sub. If you have some modding skills you can always remove the rehaut engraving that comes with the new batch.
I loved my v1. LINK. Actually I'm quite pissed off now that I traded it back then. Yes, v2 with v1 SELs is the best of the best, but that flat S dial was so great.
