Omega Seamaster 30, reference 135.007-63

Hi everyone,





I recently acquired an Omega Seamaster 30, reference 135.007-63, and I’m trying to learn more about it. What makes it particularly interesting is that the dial has the “T SWISS MADE T” marking, which I haven’t seen on any other examples of this reference online.





Watch details:


• Model: Omega Seamaster 30


• Reference: 135.007-63


• Movement: Caliber 286 (manual wind)


• Dial: “T SWISS MADE T” marking (Tritium lume)


• Case: Stainless steel


• Case back: Seamaster engraving


I would appreciate any information regarding:


1. How rare is this version with “T SWISS MADE T” dial?


2. Estimated value in today’s market? (Considering it’s in good condition and original)


3. Any historical background on this specific reference?





If anyone has come across this version before or has any insights, I’d love to hear your thoughts! Also, if needed, I can provide pictures to help with identification.





Thanks in advance for your help!

I really don’t know anything about this watch but it does look attractive. Hopefully someone will be along soon to comment. 😎
