Thank you all for the great information, recommendations and insight. I have learned more about vintage Speedmasters in the last few days than I thought possible.
Following oddboy’s advice, I have thoroughly read the information on Speedmaster101.com. I also had the opportunity to look at the watch once again, but with a different perspective using the advice received, gathered some additional information and taken better pictures to address the points brought up.
Here is the data:
- Case reference# 105.003-65
- Caliber 321
- Movement Serial # 24537xxx, which falls within the suggested range of 2282 7xxx – 2544 6xxx
- Dial characteristics, as most of you have mentioned, matches the characteristics of a 1005.003: applied metal logo, no “Professional” text, T - SWISS MADE T in the right place, and long hour indices
- Bazel black 500 with 90 (DO90) in good condition
Now, more importantly, some better photos of the watch including details of the movement, case back with respective reference and serial numbers. I take this watch falls within the "good" category, no?
