Speedmaster
This 44.25 mm stainless steel Speedmaster is the first OMEGA watch to feature the Spirate™ system launched in 2023.
It features a black "sandwich" dial adorned with a honeycomb pattern and a checkered minute track, symbolizing the watch's connection to motorsports. A black ceramic bezel with a yellow "grand feu" enamel tachymeter scale surrounds the dial.
This bold yellow is also featured in a gradient on the chronograph hand and the small seconds hand, which is striped yellow and black at 9 o'clock. The watch's 60-minute and 12-hour counters are located directly opposite, at 3 o'clock, while at 6 o'clock, on the date window, the number "10" is written in the same font as the Speedmaster logo, in homage to the anniversary of the Seamaster Aqua Terra >15,000 GAUSS.
The black, diamond-polished, beveled arrow-shaped hour markers are coated with Super-LumiNova, emitting a yellow glow. This color scheme is also found on the Speedmaster and Super Racing inscriptions on the dial.
The watch is powered by the OMEGA Co-Axial Master Chronometer calibre 9920, which meets the highest performance criteria in the watchmaking industry, as determined by METAS. It is the first movement in the world to feature OMEGA's patent-pending Spirate™ system.
This timepiece comes in a black Speedmaster case with yellow stitching adorned with a honeycomb pattern, containing a recycled nylon NATO strap with black and yellow stripes.
This 44.25 mm Speedmaster Racing Master Chronometer features a stainless steel case and bracelet. It is topped with a black ceramic bezel stamped with the iconic tachymeter scale coated in white enamel.
On the white dial, the minute track, decorated with a checkered pattern, symbolizes the watch's connection to motorsports. It also features two subdials encircled by blackened rings, as well as a date window at 6 o'clock that matches the dial's colors. The hour and minute hands and hour markers are blackened and coated with white Super-LumiNova. The orange "Speedmaster" inscription matches the tip of the central seconds hand.
The watch is powered by the OMEGA Co-Axial Master Chronometer calibre 9900 which meets the highest performance criteria of the watchmaking industry, as determined by METAS.
