In original solid silver case. It is among first true wristwatch chronograph caliber s or perhaps even the very first invented specifically to wear on wrist. Not a pocket watch movement inserted within lugged case (as it is with certain companies who claimed they made first wrist chronograph).
Case diameter (excluding lugs & crown): 35 mm. Carrying box too seems to be original of 1910s epoch. Radium-painted signed enamel dial - pleasant look, minor hair at right-counter subdial. Four-part solid silver case, unpolished. Winds, runs good; chronograph functions all good; keeps basic time.
Overall, very nicely preserved condition. I reckon, the watch was previously stored without using for quite long. Movement itself looks pretty fresh.
Whole crown serves as a push piece button for activating, stopping and reseting the chronograph. Very scarce 13''' caliber inside the item watch. In many years I saw just several chronographs powered by it. Four exemplars in gilt finished version and a single one in nickel (current actually).Moreover, all these small movements have serial numbers in conjunction with Alfred Lugrin old six-digit numeration system: 117 -118. BTW, same diapason as his larger 19 lignés chronographs (103-119).
Besides, a gilt version of this caliber carries the AlfredLugrin stamp under bridge plate (AL written within'cross' symbol). As many other manufacturers, ris has not only produced completely their own calibers but also in many cases relied on other manufacturers' stuff. Recall old LeCoultre of 1940s who nevertheless utilized Universal Geneve and Valjoux calibers very long istead of making their own serial wrist chronographs from the scratch. Facts prove this 13'' chronograph caliber was occasionaly placed in wristwaches at least during.Around 1913 it was succeeded by another 13 lignés, significantly more common now, Lugrin-Lemania caliber. (I saw the earliest watch with this caliber carrying an English mark for 1914). The later one was used by many wachmaking businesses in.
S starting from Omega till obscure brands like Escasany. Since its production lasted longer, it appears less seldom than its older relative. I saw 40 watches with it. The item also appears to be among first wrist chronographs with luminous radium dial. (Be careful with paint please and be noticed about radiation danger).
