William Penn Moon-phase Reissue - Limited Availability of 10

RGM Model 121/122-M William Penn Reissue

Back in 1999-2000, we introduced the first William Penn models. There were three versions back then: one with moon-phase, one with date, and another with a sub-second.  The case design was taken from our original model 102J jumping hour watch, the Penn version is a bit larger.

We have parts remaining to make about 10 more moon-phase models; only new Guilloché dials need to be made.

Artwork for new 18K solid gold silvered Dial

The watch is named after William Penn, the founder of Pennsylvania.


Watches will start shipping on or before February 2026

We have made a small change on the dial, as you will see on the artwork, we flipped the numbers on the power-reserve.
