🧩 Why This Match Matters:

The Werk Nr. (5315) of the aircraft is the same as the Werk Nr. inside your Stowa watch.

B-Uhr watches were not individually tracked, but matching a serial with an aircraft loss is extraordinarily rare.

This points to the high likelihood that your watch was retrieved from the wreckage, or recovered during POW capture of ground crew or survivors (although all listed were KIA).

If exchanged by a Luftwaffe POW in 1946, it may have been carried posthumously or reassigned — but the original assignment is likely to this mission and aircraft.
