eBay is littered with reduced Speedmasters so you have plenty to compare on condition and price. There are a lot in a Japan, presumably due to their comparatively small wrist sizes. Japanese examples are almost always repolished , often to as new sheen which for many is like buying a new watch despite perhaps losing the original finish.
to my untrained eye..
plus points
Leather strap looks new/almost new (not my preferred colour but it’s different)
Price seems ok (comparable to other reduced examples, at least half what you have to pay for a manual speedy)
minus points
Case back seems to have a lot of wear marks, why didn’t they polish that as well ?
Service history?
No case or papers (although not everyone keeps these things over the years, sales or house moves etc etc).
Can’t read serial in the photo - ask for it and compare/check where you can
Service costs
if you wanted to keep this example 20 years how would the ongoing service repairs outlay compare to buying a more expensive manual wind ?
Can you find a similar watch with papers and box for similar money ?
