POLJOT 17 jewels mens watch Au 20 gold plated - Soviet wind up wristwatch USSR

26 mm dia., 17 ruby jewels, lever escapement, shockproof device, sweep seconds hand, mean daily rate: from -20 to +40 s., 40-h winding, 20 mm gold plating, dial/case - 32/36 mm., weight 25 g., silvered dial with goldish-black markings and hands, black print. This is the watch of the First Moscow Watch Factory, which began to be marked with the registered trademark "POLET" ("POLJOT") since 1964. The 2609 caliber was produced from 1966 to 1976. Correct watch exploitation: to prolong the life of the watch it is necessary to wind up the watch every day at about the same time. You should rotate the watch button to the end but very gently (!!), until the process will go tight, so as not to twist it.
