Ah, but the real question is whether you were in-house produced in Germany or or simply cased and shipped from there with the German label!Thanks for the compliment, almost 4 years in London undoubtedly had some impact, maybe I even adopted British dryness but I am German.
If you're referring to the Fl 23883, congratulations, you're the 23883rd person, asking that question !What do the engraving numbers signify?
During WW II the German Air Ministry = German Reichsluftfahrtministerium (RLM) classified all "navigation instruments" from Fl. 23000 to Fl 23999. Fl 23235 for example was used for the "Armbandkompass". The Beobachtungsuhren got Fl 23883, on-board clocks got Fl 23885, Fl 23886, Fl 23887 (Bo-UK 1 and Bo UK-2).What do the engraving numbers signify?
I wondered that too, and was able to find out that it was marked on the original Fleigers. The FL=flight, 23=navigation. Not sure what exactly the 883 stands for.
Fl. 23883 and Fl. 23235
The specifications of these watches had been defined by the „Reichsluftfahrtministerium“ as well.
Due to those specifications all B-watches had the following features in common:
- A case diameter of 55 mm
- Marked on the back with FL 23883 (FL = flight, 23 = navigation)
- Equipped with large crowns in order to be used with gloves
- Hacking movement (the second hand stops when pulling out the crown / essential for a precise time setting)
- Breguet balance spring
- Regulated and tested as chronometers
- Long leather strap (to be worn on the sleeve of a flight jacket).
There have been two different types of dials (Pls. note: there are other figures available on the net. not sure whioch are correct)
Type A (Baumuster A) from 1940 to January 1941
a classic dial with numerals 1 to 11 and the triangle with two dots at 12
Type B (Baumuster B) starting in January 1941
Big minute numerals from 5 to 55 and a small inner circle with numerals for h, at the position of 60 min a triangle and a line on its top.
If your are interested in watches of WW II and their history I recommend to visit the hompage of Konrad Knirim (Militäruhren: Collectors Site for Military Timepieces) .
Funny Lencoth ;-)
Mike, when you mention B-watches having certain features, are you referring to the B vs. A dial or to another aspect? Would the engraving be as appropriate on an A dial watch as a B dial?
