Movement and Functionality
The watch operates using the manual-wind calibre 911 movement. This calibre was introduced in 1971 as a successor to the calibre 910 used in the first-generation Flightmaster.
The primary technical modification in the calibre 911 is the replacement of the 24-hour display with a dedicated subsidiary seconds dial. This change was implemented in response to pilot feedback regarding the difficulty of confirming if the watch was functioning when the chronograph was not active.
Evidence for this section
- “nd Generation OMEGA Flightmaster was introduced in 1971 using a calibre 911 with a constant second’s subsidiary dial replacing the 24-hour indication dial”
- “many pilots had complained that they were unable to tell at a glance if the watch was working”
