I had the clasp on my Moon Watch changed to an Omega micro-adjustable, and it made such a difference. Just yesterday the watchmaker called to tell me that the correct micro parts for my Seamaster 300m had arrived from Omega. Results: Man, do I love this watch.
Mid- to late-‘30s 38mm “Lincoln” powered by a Kurth Freres 300 (KF later changes its name to Certina)....have a great weekend, all. Cheers!
