Here´s a watch I picked up last week ( I love these controversial watches/topics), to be honest, not so long ago I thought it might be a Ukrainian frankenwatch, but I´ve learnt in the meantime!
The watch was produced all through the war years and even up into the early 50ies,
The watch is built nowerdays as an homage by Hanhart, which is nice to know. built into the same size case (39mm) as the 1 and 2 pusher chrono´s (Cal 40 & 41), so fairly large, using the mainplates of the Cal 40, but they called it Cal 54 . They built the watch without any of the chrono parts used.
I found a couple of references to the watch in the German Flying Time forum, and here´s the rough google translation;

5. three-hand watches for the Wehrmacht

These beautiful watches have gained more attention lately. These were hardly ever seen in the past . On their use, there are many rumors, in addition to the Air Force, they are also in the army and in the Waffen-SS in use have been. After the war there was a civil further construction until the 50s. The war had all watches a pressed stainless steel caseback. After the war there were also civilian Stülpgehäuse where the movement was inserted from above.

Interesting is the fact that this type of watch has been built almost from the beginning to the end of the war. Inside is a stripped-caliber 40 movement, known as caliber 54. It is therefore time to most universal military Hanhart watch type.

As far as I know, the watch isn´t even mentioned in Konrad Knirim´s book, only saw it once in the book Montres Militaires written by Constantin Parvulesco, so fairly scarce.

Excellent post, Warner.

The last time I examined one of these the owner said it was made late in the war to save time and money. But if I understand the translation, they were made early in the war as well. What is your understanding?

Hi Greg,
from what I´ve read about these watches, my understanding is; the chronos Cal 40 and cal 41 were built and finished, but the ones that came out of quality contol at the end of the manufacturing process and not working properly because of tolerance differences in the chrono parts, instead of dumping the faulty ones, were simply stipped of the chrono parts and used with just a subdial at 9:00...
Towards the end of the war, even the normal double sub dialed Chrono dial was used for lack of proper single sub dials, leaving the hole for the right sub dial empty.
A freind and forum Mod (Flying Time Forum) has one of these rare double sub dial variants where only the left sub dial used.
They were made from the early war years till mid fifties.
Here´s one of his which was made in the fifties laying next to a WW2 version

A member of Flying Time forum led us to another post regarding these watches, which certainly spices up the information that has already been found. Again a rough google translation; Uhrenwerkstattforum
