Thank you Nanuq, very much appreciated.
Thank you Automatico - I appreciate the insight on the various examples you have from experience. That accutron sounds unreal, very cool. I always picture the character Freddy pitching Don Drapers accutron commerical bit when thinking of accutron.
Also the 16760 GMT II what a watch ... and in that condition ! We have all be there wishing we kept a certain piece.
I guess I'll just have to monitor the tritium patina as it ages and dial back sun exposure if necessary. Thanks again everyone.
Pictures of the tritium patina. Omega 2531.80 with an early serial starting with 49 - one of the early models with the 1109 caliber movement. The tritium has an awesome tropical orange patina.
Notice the 12 o clock lume spot is darkening on the upper right, and the 9 o clock lume seems to be darkening more than the circular lume spots.
