I have for sale one of my favourite chronographs , with the famous Valjoux 23 caliber. This piece is from the late 1930’s to 1940’s. This watch has been professionally serviced and tested for 5 days. It is a nice chronograph measuring 32.5 mm without the crown and 34.5 mm with the crown. Lug size is 16 mm. It has 17 jewels and a Breguet hairspring. The dial does have some discoloration but it really adds to the character of the watch together with the case condition. The case has some plating loss, but no major dents and the lugs have no holes from underneath. New crystal installed. The watch sports some nice gold coloured hands, gold coloured raised numerals, and a telemeter.  Only top quality oils and greases where used. The correct oils on the gear train, escapement and correct greases on the keyless work and chronograph. It has a new mainspring . This movement is hard to find in great shape and working well because between the Valjoux 23 (the two sub-dial version )and later 72 c( the three sub-dial version) only 126,583 movements were made . This movement has been used by some of the top watch companies including Rolex, Breitling and Heuer. The chronograph starts, stops and resets very smoothly, and correctly. This column wheel chronograph as you can see from the movement photo is in great shape and running at 18000 bph and with the timing machine set to the correct lift angle of 52, the amplitude is strong and it is also strong with the chronograph turned on. The depthing of all the gears have been checked and corrected and the watch has been tested for a five days after servicing. The watch is running well, with a good delta in three positions and great amplitude with and without the chronograph running. In my opinion this is one of the best manual wind chronographs ever made and must for any collection.  Professionally serviced with a new crystal and mainspring. SOLD
