OMEGA Speedmaster Calibre 321 42 mm, platinum on platinum 311.90.42.30.99.002

Description

The OMEGA Speedmaster is one of world’s most iconic timepieces. Having been a part of all six lunar missions, the legendary chronograph is an impressive representation of the brand’s adventurous pioneering spirit.

Presented on a polished and brushed bracelet with vintage OMEGA logo on the clasp. This platinum model houses the iconic OMEGA Calibre 321, a movement that has been reborn for today using original specifications. Wearers can view the calibre through the sapphire-crystal caseback of the 42 mm timepiece, which has been crafted from a special platinum alloy with the use of gold (Pt950Au20).

The design also includes a black ceramic bezel with a white enamel tachymeter scale. Most notable is the step dial in black onyx, which uses 18K white gold for the indexes, and most hands. The vintage OMEGA logo is in 18K white gold. The design is completed by three unique subdials formed from a lunar meteorite.

Features

• Chronograph: The chronograph function is a mechanism for measuring time intervals. A chronograph watch can therefore be used to time events while displaying the time like any traditional watch.
• Small seconds: A hand on a sub-dial which tracks seconds typically it completes a full rotation in one minute.
• Tachymeter: A tachymeter watch has a function for measuring speed. It is a chronograph with a graduated dial on which speed can be read in kilometres per hour based on a 1000 metre distance.
• Transparent caseback: A transparent caseback – frequently made of sapphire – makes it possible to see the movement inside the watch.
