this is a superrare, Valjoux 92 powered, Skin diver chronograph from the early 60s, in overwhelmingly beautiful conditon. The Swiss brands name „Jungfrau“ (German for Virgin), could lead to a couple of flat jokes, which we will of course try to avoid. The 36mm incabloc steelcase, which we also know from Aquastar, is in great shape and features a flawless matte black dial with beautifully pumpkin toned lume on dial and in hands. the valjoux 92 has a jungfrau-signed bridge and is working perfectly in all functions. The watch comes on a black leatherstrap.
