On 21 July, 1969, when the astronauts of the fateful Apollo 11 mission landed on the moon, they were equipped with the now-famous Omega Speedmaster Moonwatch, making it the first watch ever to be worn on the moon. Five decades on, in celebration of the lunar landing’s 50th anniversary, the renowned Swiss watchmaker has unveiled the latest iteration of this historic haute horological treasure – the Speedmaster Moonwatch 321 Platinum.

Here the original Calibre 321 movement – used not only by the Apollo 11 astronauts, but also used by Ed White during the first American spacewalk in 1965 – has been painstakingly resurrected in-line with its original specifications. The refurbished mechanism, which is housed in a 44mm platinum alloy case, can be admired through its sapphire crystal caseback.

Fitted on fetching black leather straps, the Speedmaster Moonwatch 321 Platinum’s case has been inspired by the asymmetrical design that once graced the fourth generation of this iconic timepiece. What’s more its black ceramic bezel features the model’s iconic tachymetre scale in a delicate white enamel.

Finally, as an apt tribute to the watch’s lunar heritage, the subdials have been especially crafted from real moon meteorite components, making the Speedmaster Moonwatch 321 Platinum truly an out-of-this-world chronogram.
