    Last question about B-Uhr, I promise (case material)! >>>

    What was the case material, Stowa's site mentions brass, is this the standard?

    Thanks in advance again and sorry for the questioning.

    Interesting question. Both nickel and chromium were in very short supply later in the war.

    Things that really needed these alloys had to be made from inferior materials.

    I only know that the cases were not made of steel, but of a baser metal (don't know which), and covered with a thick coat of surprisingly shiny gray paint.

    Thanks again Martin.
    I was thinking it could be a copy/paste on this Stowa the "messing, lackiert" (brass, painted?) reference for the gehäuse (case?) and boden (dial?) so I wasn't askung about the paint.

    .
    The cases were made of brass with a thin nickel-silver plating and a matt grey anodising over the top.

    The ones I have seen looked like they had a coat of paint on them, rather than being anodized. I have always assumed they were original, but perhaps I am mistaken.

    What makes you think the original cases were anodized?

    I have never heard of anodizing nickel plating.

    There is room for both painted and plated cases in German war production. In late 1944, jet turbine wheels and nozzles were made from relatively low alloy steels, instead of the prefered nickel-chromium alloys the allies used; this lead to a mere 24 flight hour life for these wheels.

    If the Germans in 1944 did not have enough nickel and chromium for hot end jet engine parts, it is highly unlikely that it would be use on much lower priority items such as watch cases. This is not necessarially the case in early war production that were most likely plated with nickel or chromium.

    I am quoting GERMAN MILITARY TIMEPIECES OF W.W.II Volume 2 by Ulric of England.

    The latest date I can see is 1943.

    Well, he made be mistaken. You cannot anodize nickel or brass alloys.

    There are many other surface treatments you can do to these alloys.

    I was privileged tonight to handle (again) three original B-Uhren (Lange, Laco, Stowa).

    The Laco and Stowa definitely had a coat of paint on them ... it is the standard German Luftwaffe gray (has a specific name even, but I am not much into color codes), the same that would be used to piant aircraft, cars etc. I find this fact quite charming ... it goes well with the uncompromising attitude that characterized the B-Uhren design.

    The Lange had its coat of paint removed, and looked silverish, more like steel than brass.
    Cheers,
