I was not aware this thread was still active, but since it is, here is another entry - a non-DAYTONA 6239
Completed so far -
Installed gen T21 Converted (asymmetrical pusher/'slow beat') auto-wind A7750 to manual-wind 7760 (removed rotor, reduction & reversing wheels, which are sitting in container above watch). Movement now sounds, winds & functions similar to a V72.
To do -
Swap pushers out for Ofrei PD 61.701s (visually/functionally same as Rolex oem 23-P3-0) Gen 6mm Twinlock/tube (en route) Remove paint from chrono sweep seconds hand (probably) Low profile DW caseback (en route) Gen 7835/357 folded link bracelet or a nice strap Swap dial crown for more accurate crown (if anyone has a source for dial crowns or has a damaged 62xx dial with a good, accurate crown they do not need, please PM me) May swap tachymeter scale bezel for plain bezel (this will convert the watch from 6239 to 6238)
