Wow, thank you for those words - means awfully lot, especially coming from you whose knowledge I highly respect!
Yes, it's a service t19. Had a superdomed plexi, which I had bought from a VRM dealer I've done business with earlier. Didn't fit the bezel however, and long story short it was sent back but I never got a refund... A fellow member here was kind enough to quickly assist me with a good deal on the t19 now fitted.
Can mention for others btw that the case is a HH 5514. Akira should have most credit here, as he's the one who did the hard work (slight, but very precise reshape work of the case and the relume work on the hands to match dial). Very glad with how this build came through and the Donerix leather strap gives a good mix in the rotation (to the 7206, 6251h, 78360, 93150, phoenix bond nato just to name drop...).
