Earlier this year, Omega made a welcome announcement — the Swiss manufacture was bringing back the 321 caliber, the legendary chronograph movement that powered early Speedmasters (among others), including those that eventually made their way up to the moon. The 321 is an excellent and much-adored movement, and the news ushering its revival definitely got some buzz in collector circles. Today, on the 50th anniversary of the Apollo 11 moon landing, we’re finally seeing its official return in — you guessed it — a Speedmaster, this one dubbed the Speedmaster Moonwatch 321 Platinum.
The Speedmaster Moonwatch 321 Platinum is, as the name proudly states, rendered in a special alloy of platinum and gold (Pt950Au20). Additionally, the bezel is black ceramic, and the tachymeter scale is done in white enamel. Around back is an open window to the beautifully-finished column-wheel movement. Otherwise, the DNA of the case, with its asymmetrical form and twisted lugs, is right from reference ST 105.012.
