Object description

Case and Display Back

The watch is housed in a 42 mm steel case, notable for being among the first steel models to feature a display case back. This construction allowed for the observation of the mechanical movement, a feature described by the vendor as uncommon for brands during the mid-1980s.

The exterior of the case back features specific engravings identifying the model's association with the Speedmaster's history. It is also mentioned that the reference number is engraved between the lugs, which the vendor suggests may be a unique feature of this specific model.

Evidence for this section
  • “42 mm steel case”
  • “This is a very rare Speedmaster that was the first steel model to feature a display case back”
  • “the special case back engravings still very clear”
  • “We believe that this is the only Speedy to have the reference between the lugs too!”

Movement and Construction

The watch is powered by the manual-wind calibre 863 movement. The vendor reports that the movement has been fully serviced.

The watch is secured to the wrist via an Omega reference 1447 bracelet, noted for its similarity in design to Rolex President-style bands. The bracelet is attached to the case using 805 endlinks and features a quick-release mechanism integrated into the clasp.

Documentation and Accessories

The listing includes original packaging and documentation, which support the authenticity of the set.

Beyond the watch itself, the offering includes a handmade leather watch pouch. The inclusion of the numbered outer box corresponds with the limited-edition nature of the timepiece, which is identified as number 02xx of the 1000 units produced.
