OmegaX-33 / Z-33

The X-33 is Omega's Speedmaster for astronauts, a titanium multifunction quartz developed with NASA and ESA crews and launched in 1998. It was called the "Mars Watch", and the Z-33 of 2012 is its aviation sibling. This library holds 21 references, every one quartz and every one titanium or a titanium alloy.

About the Omega X-33 / Z-33

The first X-33 carried an alarm loud enough to be heard through a helmet, a mission timer counting elapsed days, three time zones and a chronograph, on a digital display behind analogue hands, and it flew on the Space Shuttle and the ISS. The Skywalker X-33 of 2014 was developed with ESA and added mission-elapsed and phase-elapsed timers; the Regatta and the Marstimer of 2022, which keeps time on Mars, followed. The Z-33 put the same kind of movement in a pilot's case shaped after the 1969 Flightmaster.

The 1666 of the first two X-33 generations powers 12 references, the 5619 of the Skywalker 2, the 5666 of the Z-33 3, and the 5622 of the Marstimer 1. 16 references are recorded as chronographs and 2 with an alarm.

The 42 mm case accounts for 13 references, the 45 mm Skywalker for 4 and the 43 mm Z-33 for 3, and 3 of the cases are oval. Titanium is the material of 19. Black dials account for 19. Water resistance is 30 m on 20 references. 4 are limited editions, and the rarity median is 5.

The Speedmaster Moonwatch is the mechanical chronograph the X-33 was built to succeed in orbit, and the automatic Speedmasters collection holds the rest of the line.
