My very good friend Ingo of FineWatchBuckles fame is selling his customized Panerai PAM312 with a custom DLC finish in black. I can tell you from personally seeing the watch a couple of years ago that it’s a stunner. With its incredibly hard (scratch resistant) Matte Black finish. The Watch is listed on Chrono24 here: https://www.chrono24.com/panerai/dlc-black-luminor-marina-1950-3-days-automatic–id12604872.htm
Also Ingo was kind enough to offer a 300 Euro discount to purchasers who are also customers of Dangerous9straps.
Here are some great photos which Indo has taken of the watch (BTW: I don’t believe that I made any of the fasinating strap you’ll se in this slide show):
