About the Omega Speedmaster Moonwatch

The 1957 CK2915 was the first chronograph to move the tachymeter scale from the dial to the bezel, and it carried the caliber 321, a column-wheel movement built on the Lemania 2310. The ST105.012 and 145.012 worn on Apollo 11 in 1969 used the same movement; the 145.022 of the same year replaced it with the cam-actuated 861, and the layout has not changed since. The 2019 revival of the 321 and the 2021 Moonwatch with the Master Chronometer 3861 are the two most recent chapters.

The caliber 1861, the 861 with a rhodium-plated finish, is the most common movement here at 70 references and covers the Moonwatch from 1997 to 2021; the 861 itself accounts for 14 and the 1863, its version for display casebacks, for 17. The 3861, which added a co-axial escapement, a silicon hairspring and hacking seconds, appears in 32. The 1866 moon-phase and the revived 321 account for the rest. The Lemania piece explains why the 321 is the movement collectors prefer.

The 42 mm case accounts for 148 of the 161 references. Steel is the material for 97, with yellow gold, white gold, Sedna gold and platinum in the anniversary editions. The crystal is the collection's other dividing line: 76 references have the hesalite the NASA watches used, and 83 the sapphire. Water resistance is 50 m on 153 references. 88 of the 161 are limited editions, more than half the collection, from the Apollo and Snoopy series to the Speedy Tuesday models.

The automatic Speedmasters are the other half of the line, the '57 and Broad Arrow revive the 1957 design, and the First Omega in Space is the 1962 CK2998 reissue.
