OMEGA’s Speedmaster Grey Side of the Moon is an innovative addition to the Speedmaster collection.
With its grey ceramic case, sand-blasted platinum 950 dial, Moonwatch-style hands, ceramic bezel and tachymetric scale in white Super-LumiNova, this timepiece is not only ready for adventure but is stylish beyond compare.
Reminiscent of its legendary predecessors, the Speedmaster Grey Side of the Moon has a 60-minute and 12-hour recorder at 3 o’clock and a small seconds sub-dial at 9 o’clock. OMEGA’s Co-Axial calibre 9300 can be seen through the bevelled sapphire crystal caseback.
New to this model is the ceramic and titanium foldover clasp.

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.
Chronometer: Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).
Date: The day of the month, displayed in a window on a watch dial at the 3 or 6 o’clock position, or within a subdial at 9 o'clock.
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.
Time zone function: Allows the hour hand to be easily adjusted to different time zones without stopping the watch.
Transparent caseback: A transparent caseback - frequently made of sapphire - makes it possible to see the movement inside the watch.
