Omega Speedmaster Mark II 42.4×46.2mm steel-Sedna gold on steel-Sedna gold

The OMEGA Speedmaster is one of OMEGA’s most iconic timepieces, perfectly representing the brand’s pioneering spirit.
For this model, the dial has been created in matt grey, with a white minute track, as well as transferred white hour-markers coated in Super-LumiNova, the same technology used on the white-black hour-minute hands, and white central second hand.
Most strikingly, the 42.40 mm case and polished-brushed bracelet have both been made from stainless steel and 18K Sedna gold. This exclusive rose gold alloy has also been used on the tachymeter scale, inner ring, crown and pushers, and 3 subdial rings.
There is a small seconds recorder at 9 o’clock, a date window and 12-hour recorder at 6 o’clock, and a 30-minute recorder at 3 o’clock.
On the inside, this model is driven by the OMEGA Co-Axial calibre 3330.
