19”’ | Hand Wind | Swiss Lever | Small Seconds |

Remarks:

• Pillar construction
• Locust was a trademark registered by Henri-Albert Didisheim, Switzerland, in 1904. He manufactured watch movements and pocket watches.
• His brother Hippolyte Didisheim emigrated to the U.S. to to supply the U.S. market with the family-owned company’s watches and movements. He also used the trademark Locust.
• The movement is marked ARISTES. Aristes Township and Locust are two small towns in Pennsylvania, USA, that are only about 11 km apart. Just a coincidence?
