This is one of my Grandfather’s watches. I would like to ask for some help and guidance for finding the proper crystal for this watch. I have searched and searched but I can not match any of the numbers I have to anything I have found online. This really has me stumped. Here is the information I have with a few pictures also. Omega Seamaster Calendar Calibre: 502 Movement Serial Number: 17073574 Numbers inside case: KX6275 E76553 I know I would probably need to remove the crystal to measure it precisely. I would rather not remove it at this time. the measurement below are as close as I could determine with the crystal still mounted on the case. Diameter: 29.464mm Height: 4.064mm If anyone could steer me in the right direction to locate the proper crystal I would appreciate it.
First. Remove that metal bracelet from the watch. Will damage the lugs. Email Jules Borel or Otto Frei. Supply the movement caliber and case back numbers They use these to find the right crystal. DON
Proper Omega crystal is 063PX5042. Watch is in desperate need of a service by the looks of things, so find a watchmaker with an Omega parts account to get the watch serviced, and they can supply the crystal at the same time. Cheers, Al
