bethfob 42 · July 31, 2014

Serial Number 1566361 was reported as inaccurate.

Note: My pocket watch movement is an openface movement,
the winder is at the 12'o clock position. The
seconds sub part is positioned at the 3'o clock
position not at the 6 as normally seen
Curator Response: Thanks for the information. It sounds like your watch has a conversion dial, which would allow the watch to be set similar to an openface movement. The conversion dial essentially places everything in a different position.
