Tschuy-Vogt or Tevo, was registered; 1926 in Grenchen Switzerland. The brand did not make in-house movements, but rather put together watches with: hands, dials, movements and cases bought from various manufactures to generic specifications. You can find several Bucherer watches put together by Tevo. This Particular watch was for the Swedish market, it’s got a very robust Wehrmachtswerk; A.Shild calibre 1560 a lovely black guilt dial packed into a robust stainless steel case. It was in a very sorry state and I thought it deserved a full service/repair to bring it back to the land of the ticking.
