Notes

Dial, case and movement signed. DIAM. 42 mm. THICKNESS 14 mm. Approx. overall length 175 mm. Almost unknown to the market, this extremely rare SPEEDMASTER was most certainly made as a special request. Correspondance with OMEGA BIENNE as well as the extract confirms that only 10 watches were ordered at the time and that the engraving on the caseback were made by Omega themselves before delivery.
