Revolution Writes About the RGM William Penn Model 121-M

By Keith W. Strandberg   


William Penn founded the state of Pennsylvania in the USA, promising many fundamental freedoms, including the freedom of religion. As a result, many immigrants, fleeing religious persecution, came to and settled in Pennsylvania (including the Amish).

RGM, based in Mount Joy, PA, debuted the William Penn collection, consisting of three models (one with sub-second, one with date and one with a moon phase), about 18 years ago. Now, RGM is reissuing the William Penn in a moon phase version only, using new old stock.





“I have always loved the William Penn models but when we introduced them back around the year 2000, big watches were taking over, and the Penn models were considered too small, at 40mm, for many collectors,” RGM’s founder Roland Murphy explains. “Today, sizes are coming down a bit and the Penn is now not too small for many watch lovers. We had enough parts to make 10 watches with the moon phase, and we only needed dials. So, we got to work and made new engine-turned dials for the 10 watches. To date, we have sold six of the 10 we can build.”







The William Penn is available in 316L stainless steel or 18K rose gold.
