Speedmaster Dark Side of the Moon 44.25 mm

It was the adventures and the accomplishments of the Apollo 8 astronauts that inspired the all-black, ceramic Speedmaster Dark Side of the Moon, but it is the mystique of the Earth’s nightlight and its ever-changing yet constant presence that has spurred the creation of the Speedmaster Dark Side of the Moon "Sedna Black".
This 44.25 mm model has a completely brushed black ceramic case with an 18K Sedna™ gold bezel ring which matches the 18 Sedna™ gold applied indexes and hands. The marks on the matt grey dial have been created using laser ablation.
The "Sedna Black" is presented on a black leather strap with a brushed ceramic foldover clasp. At its heart is the OMEGA Co-Axial calibre 9300.

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.
