Discovered that Jeff's (RLX-lvr) red and mine are only 76 watches apart
- makes me wonder about the conditions that caused his dial to turn brown and why mine stayed black. DRSD.com says that the 2.2 to 2.3 serial # dials were the ones most likely to change.
Copied from DRSD.com:
The Brown Sub variant, as rare as it is beautiful, was most likely spawned from a manufacturing flaw. This makes it highly sought by collectors worldwide. I would consider a “Chocolate Sub” a grail watch! In my experience, Brown Dial Subs are only found in Meters First Mark II & Mark III dials and typically in case numbers in the 2.2M or 2.3M ranges. Brown dial subs are Ultra Rare because it is likely that only a small fraction of the dials turned brown and many if not most of those dials were probably destroyed or replaced during service.
