Condition
The Aluminum Case has very minor wear (see pictures).
Both the inner and outer glass are in very good condition (no damage / discoloration).
The “Stop à 0 à Go” switch knob is missing [This is the only piece / part missing].
All of the screws are original and in good condition:
- 4 on front of case
- 3 that hold the knobs in place
- 3 on back of case that hold the movement
- 1 large on back of case for access to speed adjustment
There are 4 small clear bulbs, which shine though a white film / plastic on the edge of the inner glass to illuminate the clock.
Unfortunately, I have no way of testing the bulbs / lighting, nor do I know what voltage they are.
The Movement is complete (see pictures) and is very clean.
The jewels where the balance wheel resides need replaced.
The balance wheel itself appears to be in good condition.
The clock will run with a little coaxing, but due to the worn jewels, it will typically only run for a few seconds up to a few minutes.
I've tested all of the functions (elapsed time runs and resets, chronograph runs and resets, time runs and can be changed) and all appear to be working as designed.
So, once the worn jewels are replaced, this clock / timer should be good to go.

Additional Information
Manufactured by LeCoultre for Aerosonic (hence both Aerosonic and LeCoultre on the Dial).
Aerosonic has been in business since 1953 and supplies both the Private and Military Aircraft Industries.
Based on 1 website, there was a virtually identical clock made by Breitling for Wakmann that was used in the Boeing 727.
The Boeing 727 was produced from 1962 until 1984.
A second website says this clock was made for Boeing.
So, I believe this clock was also made for the Boeing 727 or similar Boeing aircraft, probably in the same timeframe (1962 - 1984).
Based on the markings on the movement, I believe the caliber / movement number is 334 (with 15 jewels).
334-15
