1950s black dial Dreffa Geneve Chronograph Suisse watch, Valjoux 92 movement.
 
A desirable black dial and rose gold coloured case Chronograph from the 1950s. The case is well proportioned for the 1950s at 34.5mm wide without crown.
 
The dial is beautiful, with a black gloss finish and gold writing. The dial has excellent balance with sub-dials at 9 and 3, with large Arabic numerals at 12 and 6.
 
It has a high quality Valjoux 92 movement, which has a rose gold gilt finish. The movement is incredibly clean, with no scratching or corrosion. The watch keeps time to within +5 seconds a day, with an amplitude of 290 degrees and a beat error of 0.1m/s.
 
The dial is a tachymeter which has a Base 1000 Telemetre signing. This allows the measurement of distance by timing the travel over the distance while the speed is held constant.
 
The case is rose gold plated and in very good condition with no wear on the case or between the lugs. The crown and pushers have some wear to the plating. The black dial has a gloss finish and is in excellent condition with no wear or spotting. The sub-second dials are sunk with a circular graining.
 
Overall this is a beautiful chronograph, with a black and gold colour combination, a high grade movement, and is in excellent condition.
