Omega Seamaster Automatic 24 Jewels cal. 552 advice

Hi everyone,

I’m considering purchasing a vintage Omega Seamaster with the Caliber 552, and I’d love some advice before pulling the trigger. The watch has recently been serviced, and the seller provided a timing report (attached below).

A few questions for those more experienced:

1. Are the timekeeping numbers in this report a good sign for a well-running movement? The Delta seems within Omega specs, and the amplitude looks reasonable, but I’d appreciate a second opinion.
2. Can't really tell if it is gold plated / gold capped?
3. Anything else I should check or ask before finalizing the deal?

The seller is asking ~$1,350, which seems a bit high? but I’d love to hear if that aligns with market value.

Thanks in advance for any insights!
