E. F. Bowman Watches by RGM

Here at RGM Watch Co., we have reintroduced the historic E.F. Bowman watches as part of our high-grade watch offerings. Linking past and present.

E.F. Bowman has a long history here in Lancaster County, Pennsylvania; in fact, RGM’s Roland Murphy attended the Bowman Technical School in the early 1980’s. It’s a natural fit for RGM to revive the historic name on watches created in Pennsylvania once again.

RGM Model 501-EFB

Constructed using timeless techniques that were used in fine mechanical watches of the past, like the original American-made E. F. Bowman pocket watches of the late 1800s. 

The 1920s Patek Philippe pocket watch pictured below, which Patek Philippe originally made for Ezra F. Bowman & Sons, inspired the unique dial and hands of the new Model 501-EFB wristwatch.
