I have been working this TST since March, I had most of the parts I needed and an Idea of what I wanted to Wind up with (pun intended). I had to wait for gaskets, Jewels, Bridges, Custom Mill work from My Favorite Member. Yes, I have a Favorite Professional. This Watch has been through many changes, Only because I wanted to wear it in between adding parts etc.... So now It is Buttoned up, Completed, Finished....The upgrades are this...Started with a 6309 Movement, Jeweled Mainspring Ports, 6306 Hacking Lever, 6306 Train wheel bridge, Both NOS, Custom Milled Center Wheel bridge, New Mainspring, Black Day/Date wheels, 1000M 7C46 Dial, NOS 6309 H/M hands, Second Hand from a Golden Tuna to accent the Brass Crown, Which I Love, Thanks a Mint John. All in All The result is better than I expected. Without further Ado ...Oh, The Strap...WatchGecko 22mm Divers Strap, None Better for myself. And everything is SOOOOO Smooth !!!!
