Fooled by the picture I guess.
Yes, magnified pictures are a bit deceptive, I actually thought the gold Tri-Compax with the claw lugs looks a bit funny under magnification ! This 18k HJ case Tri-Compax is probably an early one that is somewhat of an anomaly. When I got it it had a redial. The current dial is a service dial, I'm going to replace it with a very old deco numeral Tri-Compax dial. Just need some hands that would match the dial.
Here is what appears to be a gold HJ case for a Compax - so we know they weren't just made for Compurs. If it was made for compurs and compax maybe it was also engineered for Tri's.
This is a UG sales catalog I saw on ebay from the 40s.
