There's some really cool reps of no cg subs posted here.
I have always started my vintage reps with the dial. A few years ago I bought a pretty nice dial second hand, and then discovered the case/dial issues.
So off to search for a case, and this is what I found:
Rolex sub, 6538 case 37mm, dial 26.5mm
Yuki case 37mm, dial 27mm
Ndt case 38mm, dial 27mm
Ingod44 dial 26.5mm
Raffles case 38.5, 28mm dial
Helenarou/Rouhelena case 39mm, 29mm dial
Tiger Tudor case 37.5mm, 29mm dial
Phong case (assume 37mm) dial 26mm
MQ case (assume 37mm) dial 27mm
As noted, the rep cases and dials are all over the map.
What I found out, other than Yuki (6-700$, Phong (14-1500$), and MQ (omg ????$)....there are no rep 37mm cases that accept a correct 26.5/27mm dial.
I never looked into the Silex or cartel watches and don't know much about sizes there.
Whole thing is frustrating for me, I have seen many of the 29mm dialed watches and they just don't work for me, let alone the subtleties of the case curves Nanuq mentioned.
I wish MBW had made this series watch. Someday I might afford a phong..we will see.
Eta: I love this style sub, and just like vintage Daytona's- this is one watch that really takes money to get close.
