pocket watch with a Illinois movement S/N Brevet
N15828 in a Wallonia .800 sterling silver and 7k
Rose Gold Open Face snap back and dust cover case.
The crystal is pristine and it has a plain no logo
enamel face with Arabic numerals in fine condition
except for Mark's in the 8 and 9 position. The
second hand is not original. Fine running
condition but gains 5 mins every 12 hours. It is
Pendant wound and set. I hope this is appropriate
