1991 Speedmaster Questions

Sub74N

Hi everyone,

I've been hunting for an older Speedmaster, either a 145.022 from the 70s or one from my birth year. I happened upon this one on eBay that has box and papers and it dates to my birth year and month!

I asked the seller for movement shots and serial number. For 1991, let me know if I have the following facts straight:

• 145.022 reference number is still being made
• serial number should only be found on movement, not on lugs
• Long S and R is appropriate for a 1991 dial
• Tachymetre should have no serif on the 7, DNN, and no accent on the E.

A couple of things about this particular listing that I noticed:

• The bracelet looks older to me than what would have come on a Speedy of the early 90s. maybe a 1171? I asked for a shot of the number on the clasp. Waiting to hear back.
• The caseback looks like it's in better shape than the rest of the watch (maybe I'm wrong), maybe it's a service part. I'm not opposed to some service parts, but would not want to pull the trigger on a complete frankenwatch.

Let me know what you think about this listing, and if you would go for it if you were looking for a birth year Speedy. Thank you so much!
