Foire de Bâle 1964 Foire de Bâle 1964 Sandoz — 307435
Swiss Watch Fair 1964 Perfection by the Swiss watch industry of new waterproofing techniques has led to the introduction of new diver's timepieces which can withstand pressures which were the province of highly expensive special models until recently. This watch is a good example of the new trend. Guaranted to be fully waterproof up to 3,300 feet (î ,000 metres) depth it has an automatic movement, a date calendar and a revolving outer bezel.
