    Hi, thanks for your reply. This telemetric bezel is graduated to indicate the speed in air. It allows the user to calculate the distance between the observer and a situation that is observable both visually and audibly. It was mainly used for military purpose and weather situations. For more details please see Chronomaddox.com/4bezels.

    My watch was delivered to RCAF in july 1966, so probably for military use. Best regards !

    For the uninitiated among us: See the flash, start chronograph. Hear the noise, stop chronograph. Wherever the pointer is lined up on the tachy indicates how far away the flash originated.

    Ah, of course! 20km/min = 1200km/h = Mach 1 give or take a tad. Very cool. But the URL you cited doesn't appear to be valid. :(

    EDIT: Found the correct URL: http://chronomaddox.com/4bezels.html Thanks!

    One has to wonder at the usefulness of it in an aircraft ca.1966 though - I wouldn't have thought you'd hear anything more than a kilometer or two away. But on second thoughts, this was during the Cold War so potential blasts were probably expected to be pretty loud!

    Imo more for ground stuff. But take into consideration that most of the older (esp. the 40s/50s) chronos already had this feature. So there might be some reasons for Omega to offer that option for their speedies.

    Add the Omega 20mm buckle and it vastly improves any NATO (part 94512002)
