This is a very cool 43mm steel case with rotating black bezel that is the same model as those issued to the German Bundeswher or Federal Defence Force.

The black dial features the desirable red ‘3H’ making that signifies Hydrogen 3 or as we know it better tritium and this particular version is a so-called Small T, due to the marking over the six o’clock marker.

The matte case is in great condition. The dial features bold Arabic painted numerals in zinc-sulphide tritium that have a lovely yellow patina this is a good match with the lume in the hands. The hands have been stabilised at some point. The watch comes on the pictured Bulang and Sons strap and the Valjoux 230 calibre has been fully serviced by our watchmaker.

We would love to talk about this cool chrono some more with you. Get in touch to arrange a visit or call!
