ID 3590.50 Speedmaster Professional Cal.861

Hi!

I'm interested to buy this 3590.50 Speedmaster Professional Cal.861 from the early 90s. Photos are not so good but the price and model are good for me. I tough I run it through your expert eyes. Anyone can point out suspicious details I could miss?

Thank you!

If I were you, I would reach out to the seller and ask for lots of high quality photos from every angle including of the open case back. If it is a legitimate dealer, they should have no problem providing them to you. Once you have better photos, post them with a detailed write up that includes your overall opinion of the watch and what concerns you have, as well as what specific questions you have. That will make it easier for the community to give you guidance. I'm still new to the community myself, but I think it is difficult to respond to your post based on the limited information you have provided.
