Maker History
Piquette wristwatches were produced by the Langendorf Watch Company, a Swiss manufacturer operating from 1873 to 1973. While “Langendorf” was their primary brand, they also released watches under various names, including the rare “Piquette” line, which featured AMKO-branded movements. The Piquette watches are noted for their quality and are considered collectible items today. However, detailed historical information is limited and hard to find. 
Servicing this Piquette Watch
This particular wristwatch isn’t extraordinary cosmetically, but the movement is of a good quality and it ran well after service. It is housed in a fine gold case, with nice vintage dial.
