1970s Yema jumbo Yachtingraf “White Ship”

This is one of the best examples of an extremely rare watch. From 1969, Yema produced a handful of regatta chronographs featuring a 10 minutes countdown instead of the traditional second chronograph disc. Based on a modified Valjoux 7733, these watches were produced in the strong and distinctive 850737 Yema case, thick, large (42mm) and with beautifully designed crown-guards.

It is commonly admitted that only 25 of them are known, which makes it a very hard catch. And as you will admit that the condition of the example we are offering is simply outstanding, we are not afraid to say that this one is among the bests, if not the best, examples out there.

The watch is in outstanding condition. The very nice matte black dial is perfect, showing a crazy patina, perfectly matching the thick hands. The rotating bezel is in very nice condition and rotates freely as it should. The case looks excellent. It comes on a vintage NOS steel bracelet.
