Having participated in all six lunar missions, the legendary OMEGA Speedmaster is one of the most iconic watches in the world. This model has revisited the famous caliber 321, which was an important part of the Speedmaster's original space history.

The 39.70 mm case is made of noble steel and is inspired by the same style of the third generation used during the first American spacewalk in 1965. It also has a polished black ceramic [ZrO2] bezel ring, with the tachymeter scale in white enamel.

The black chamfered dial features the familiar Moonwatch hands, a vintage OMEGA logo, a small seconds hand, a 30-minute counter, a 12-hour counter and a central chronograph seconds hand. Through the sapphire crystal caseback, you can see the caliber 321.
