Omega "Speedmaster Professional"
, Movement No. 0001642, Case No. 2413, Cal. 861, 42 mm, circa 1970
An important Omega PROTOTYPE with chronograph, 30-minute and 12-hour counters, subsidiary seconds, tachy scale and bidirectional rotating bezel with 60 minutes division
Case: steel, screw back, anti-magnetic protection cap, folded "Omega" steel bracelet ref. 1039 with deployant clasp dated 1/69, endlinks stamped 516, bracelet length 145 mm, total length 180 mm. Dial: black, silver tachy scale.
The statement made by the Omega museum on September 17, 2019 says: "Il s'agit bien d'un prototype Speedmaster avec lunette tournante mais malheureusement pas d'extrait possible car les archives ne répertorie pas les prototypes avec les mouvements commençant par '0000'" ("This is a SPEEDMASTER-PROTOTYPE with rotating bezel, but unfortunately a copy from the archives cannot be produced because prototypes with movement numbers starting with "000" are not listed in the records.").
There are several differences between this prototype and other Speedmaster Professionals – the silvery tachy scale sits on the dial and not on the bezel as is conventional practice. The bezel is bi-directional with 60-minute divisions. The otherwise blank caseback does not carry the usual Speedmaster Professional six-figure reference number but the four-figure number "2413" near the edge and seems to be for internal records purposes in reference to the project.
The authenticity of this prototype is confirmed and offers a unique chance to purchase a timepiece which, to the best of our knowledge, has never been offered on the market with a dial/bezel combination of this kind.
