The Omega caliber 5619 multi-function quartz movement was introduced with the launch of the Skywalker X-33 ani-digi Speedmaster (Ref: 3184.108.40.206.03.001).
Omega officially lists this caliber number as 5619 on their site, but the actual number on the movement is 5619A. There is also another number that can be seen on the movement: AT05H2.
Official description from Omega:
“Highly precise thermo-compensated multi-functional quartz movement with special functions developed and tested and qualified by the European Space Agency (ESA). It powers the Omega Speedmaster Skywalker X-33 whose analog hands and LCD windows display, among other values: three different time zones, chronograph, timer, MET (Mission Elapsed Time), PET (Phase Elapsed Time), three alarms and perpetual calendar.”
- Chronograph: countdown and flyback
- Multiple time zones
- 24 hours
- Perpetual calendar until year 2100
- Stand-by mode
- Low battery indicator
Watches with this movement have four pushers and a crown that also acts as a button when pushed in.
Although quartz watches are known for their superior accuracy when compared to mechanical movements, the biggest potential challenge to maintaining accuracy is a change in temperature. High accuracy thermocompensated quartz movements are equipped with technology that ensures stable timekeeping despite fluctuation in temps.
While we do not have exact claims from Omega. Thermocompensated movements are known to be accurate between +/-5 to +/-25 seconds per year. For a quartz movement to pass COSC standards, it must have a daily average rate of +/-25.55 seconds per year. The caliber 5619 is a COSC certified movement.
Developed for Space
The caliber 5619 movement was developed under a European Space Agency patent license based on an invention by ESA astronaut Jean-François Clervoy. The patent in which is owned by the ESA, is one of 135 inventions and is available for commercial use by non-space related industries.
