William Penn Moon-phase - Reissue - Limited Availability of 10 pieces   

The Original William Penn

Model 121/122-M

Back in 1999-2000, we introduced the first William Penn models. There were three versions available at the time: one with a moon-phase display, one with a date display, and another with a sub-second display. The case design was inspired by our original model 102J jumping hour watch; the Penn version is slightly larger.

We have parts remaining to produce approximately 10 more moon-phase models; only new Guilloché dials need to be made. We have made a minor change to the dial, as you will see in the artwork, where we flipped the numbers on the power reserve.

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