Omega Speedmaster Moonwatch Professional Caliber 321 platinum bracelet 42 mm

The rebirth of a myth: The Speedmaster Calibre 321 Platinum

At the start of 2019, Omega announced the return of the legendary caliber 321, a faithful recreation of the movement that powered the iconic Speedmaster from its introduction in 1957 until around 1968. This historic movement has been integrated into a platinum Moonwatch, a collector's item featuring an onyx and meteorite dial. This special edition, followed by the Speedmaster “Ed White” Moonwatch in steel, quickly captured the hearts of watch enthusiasts.

An exclusive platinum edition

Omega has discreetly launched an all-platinum version of the Moonwatch 321, now equipped with a matching platinum bracelet, in addition to the black leather strap available since 2019. This platinum edition, marks a new stage in the evolution of the Speedmaster, propelling it a new stratosphere.

The case of this Speedmaster Calibre 321 Platinum is a classic Moonwatch, with its asymmetrical design and lyre-shaped lugs. With a diameter of 42 mm and a length of 47.6 mm, it is made from a special alloy of platinum with gold (Pt950Au20). The black ceramic bezel, adorned with a white enamel tachymeter scale, is reminiscent of stainless steel models, while adding an extra touch of sophistication.

The dial of this watch is a true work of art, with a black onyx base and three sub-dials in gray lunar meteorite. The hands, applied hour markers and vintage Ω logo are in polished 18k white gold, adding a refined elegance to the whole. The real appeal of this reference 311.90.42.30.99.002 lies in its platinum bracelet, designed in an “Ed White” flat-link style, offering a subtle contrast to the traditional design of steel Moonwatches.

A historic and prestigious movement

The caliber 321 is an iconic Omega movement, first introduced in 1946 and used in the first Speedmaster in 1957. This hand-wound chronograph movement is famous for its precision and reliability, qualities that contributed to its use in NASA's space missions, including the Apollo missions.

The caliber 321 is particularly appreciated for its column-wheel architecture and horizontal clutch, which offer smooth and precise chronograph activation. Omega has reissued this movement in 2019, using modern manufacturing techniques to faithfully recreate the original design.

The new version of the caliber 321 retains the 2.5 Hz (18,000 vibrations per hour) frequency of the original, as well as its 55-hour power reserve. The movement is finished by hand, with a Sedna gold coating to mimic the appearance of historic movements. This movement is a tribute to Omega's watchmaking heritage and a testament to its commitment to innovation and quality.

The ultimate Speedmaster?

With its platinum case and bracelet, Onyx dial with lunar meteorite inclusions, and Omega's most fascinating chronograph movement, this watch embodies the ultimate evolution of the Speedmaster. Originally conceived as an instrument for pilots, it has evolved to become a priceless collector's item. Is this the ultimate Speedmaster Moonwatch? Surely, we can't see how Omega can make it even more legendary and exclusive!
