CAL. 321

Caliber 321

The legendary OMEGA Speedmaster, one of the protagonists of all six lunar missions, is one of the most iconic watches in the world. This model is inspired by the famous Caliber 321, an element of central importance in the history of the Speedmaster's space exploration.

The 39.70mm stainless steel case is inspired by the same 3rd generation model worn by astronaut Ed White during America's first spacewalk in 1965. The model also features a polished black ceramic bezel ring [ZrO2] with tachymeter scale in white enamel.

Featuring traditional Moonwatch hands and the vintage OMEGA logo, the black “step” dial features a small seconds counter, 30-minute and 12-hour counters, and central chronograph hand. The Caliber 321 inside is visible through the sapphire crystal caseback.
