Omega Speedmaster 105.012 -65 HF
Cal. 321 (serial 265xxxxx - later 321 production but still correct calibre)
Original 1039 bracelet with 516 end links
Crown and movement cover are service replacement (not original)

This is the same model worn by Neil Armstrong and Buzz Aldrin (105.012) during the moon landing.

Bought this watch from very trusted private seller on Omega Forums (he has sold many, many watches there - I can share name and emails for proof for serious enquiries).

Please NOTE:
- everything looks original except crown and movement cover - these are still original Omega parts but are service replacement. This has correct 321 calibre movement, but serial number is later than 105.012 production.
- bracelet is long enough for wrist up to approximately 6.5 inch.
- watch needs a service. It is running fast by 90 mins over 24 hours. It was last serviced by Classic Watch Repair (TST) in 2016.
