Swiss Watch Fair 1970 BF 10
An example of the improved protection from which watches benefit today. This town-wear model is also quite suitable for sports thanks to its case with water-resistance guaranteed to 20 atmospheres (a depth of 200 metres). Screwed-down winding crown. Automatic movement with ball bearing, day and date calendar. The case is available either in steel or in 20-micron goldplate. (TECHNOS “Sky Light”)
