I'm a little confused about the operation at Hanhart between 1945 and 1948 when the French took over (and eventually issued their Type 20). I often see Hanhart two pusher chronos, Cal. 42 with big screw in the middle clearly produced after the war, but the case and dial combinations as well as serial number pattern can differ quite a bit. Some, presumably the earliest post-war examples, have cases identical with the wartime issues, identical dial, caseback. It may be that some are chrome plated rather than nickel plated but from pictures it's not always easy to tell. In all cases the serial number is missing on the back and the number on the movement was reset and started from 0 (no longer continued the numbering of wartime production). From what I've seen the numbers under 2500 seem to be closer to the Luftwaffe issued chronos. I'm assuming that parts left in stock at the end of the war were used to make these watches. However, other Hanharts fitted with cal. 42 have different dials and cases and pushers. I see them with serial numbers as low as 4000.
I wonder if anyone knows more about these early postwar Hanhart watches. Who were they made for? I know Dr. Kurtz made c. 2000 Tutima watches for American pilots, also with existing parts, but continued the numbering used at Glashutte. Could Hanhart have produced watches for the same purpose in 1945?
Please feel free to respond in German. I can read but I don't have enough practice writing.
