VTG Elgin 691-678 24 hour Military Aircraft Gun / Bomb Camera Watch Runs

Description

Here is a vintage military Elgin 691-678 24 hour Bomb Camera or Gun Camera Clock. Runs and keeps good time.
Designed for recording timestamps in a film based "gun camera" or “bomb camera” mounted to the side of a military aircraft.
Gun cameras were used on military aircraft to record damage to enemy targets, and military intelligence specialists found it useful to have a timestamp attached to each photo. To provide this, a small clock would be mounted inside the camera; a series of prisms would superimpose the clock face in a corner of the camera's field of view, which would then be recorded every time the camera took a picture.
Movement type is typically used for 24 hour wristwatches. Has an external crown for winding and setting similar to the type found on a wristwatch. In operation these types of clocks would be mounted in a removable compartment on the camera and would need to be wound and set before the start of a mission.
Case does have scratches and scuffs from being moved around in storage. But it looks amazing for it age.
This is a magnificent horological example . Great for any military fan.
Watch clock is being sold “as is” with no warranty. No box and no papers. No returns, so please see all photos for conditioning. Photos are part of the description.
