Venus Cal. 170 is a hand-winding column wheel chronograph movement with distinctive 6-12 subdial arrangement. The 12:00 register includes 30 or 45 minute chronograph counter. It is the only Venus movement with eight columns rather than seven.
Cal. 170 was produced from about 1942 until about 1960.
Although often noted as measuring 28.2 mm in diameter, the official Venus technical documentation lists it at 28.00 mm by 6.00 mm.
