Omega Speedmaster Super Racing 44.25mm steel on steel

This 44.25 mm Speedmaster in stainless steel is the first OMEGA timepiece to include the Spirate System released in 2023.
It has a black sandwich dial with honeycomb pattern, featuring the racing style minute-track which gives the watch its name. Framing the dial is a black ceramic bezel ring with tachymeter scale in yellow “grand feu” enamel.
This bold yellow shade is also used on the gradient chronograph hand, and yellow and black striped small seconds hand at 9 o’clock. The watch’s 60 minute/12 hour recorder is directly opposite at 3 o’clock, while at 6 o’clock there’s a date window in which the “10” appears in Speedmaster logo font, as a tribute to anniversary of the Seamaster Aqua Terra >15’000 GAUSS.
The diamond-polished and bevelled black arrowhead indexes are filled with yellow Super-LumiNova, which emits a yellow glow. This colour code extends to the Speedmaster and Super Racing wording on the dial.
Powering the watch is OMEGA’s Co-Axial Master Chronometer 9920, certified by METAS at the industry’s highest standard. The first movement in the world to include OMEGA’s patent-pending Spirate System.
The timepiece is delivered in a honeycomb pattern Speedmaster watch box in black with yellow stitching, which includes a recycled nylon NATO strap with black and yellow stripes.
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.
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.
Master Chronometer Certified
Guaranteeing the Swiss industry’s highest standard of precision, performance and magnetic-resistance, as set by the Swiss Federal Institute of Metrology.
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.
