It is interesting that the case body is in brass. During the war years when supplies of raw materials were limited, a number of Swiss manufacturers used brass cases for the pilots’ watches they supplied to the British government including Jaeger LeCoultre, which adopted this approach for its famous Mark X. Though it isn’t something we see in current watch models today, the concept of brass for watch cases worked extremely well and they have no disadvantages over their steel equivalents.

Quite correctly, the screw on Oyster case back is in stainless steel.

Has anyone seen or heard of any other brass-case Tudors before? The idea of gold-plating brass was also new to me. Anyway, just found it interesting
