Speedmaster Anniversary Series 42 mm

Marking the golden anniversary of the OMEGA watch that was gifted to astronauts in 1969 to celebrate the first moon landing, OMEGA has produced this Speedmaster limited to 1,014 pieces, driven by the manual-winding OMEGA Master Chronometer Calibre 3861.18K Moonshine™ gold has been used to create this commemorative timepiece. The vertically brushed step dial, also in 18K Moonshine™ gold, includes facetted onyx hour markers. Inspired by the piece of 1969, a few touches of burgundy have been added, including the ceramic bezel ring, the markings on the caseback and the movement.The inner decorative caseback ring, crafted from 18K Moonshine™ gold and blackened, features a partial world map of the American continent and a domed lunar meteorite inlay, representing the true proportions of the Earth and the Moon.

Features
Anti-magnetic: The movement is unaffected by exposure to strong magnetic fields, even those greater than 1.5 tesla (15,000 gauss).
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.
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Limited edition: A series of watches whose production run is determined in advance of production and limited to a set number.
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.
