Stopwatch SOS PR-2B


Quick Overview

Stopwatch mechanical SOS PR-2B is designed for measuring time in minutes, seconds and fractions of a second. It is also used in scientific research as well as in motion- and-time study.
  The mechanism of the 42-mm stopwatch on 16 ruby ​​stones has a spring-driven motor, an anchor escapement and a "balance-spiral" vibration system with a vibration period of 0.4 s.
  The operating period from one complete winding-up is no fewer than 18 hours.

  The operating period from one complete winding-up is no fewer than 18 hours.
  For controlling the indicating hands, the stopwatch mechanism is equipped with a special summation action device. Start, stop of the indicating hands is handled by pressing the crown, return to zero – by pressing the button.
   The stopwatch has a 60-second dial graduated in 0.2-second and a 60-minute counter graduated in 1 min.
   The case of the stopwatch is metallic, chrome-plated.
