Read on for some more luscious pictures and RGM’s press release:

[Press Release] The new year ushered in an exciting opportunity for RGM Watch to unveil to the international community their new Pennsylvania Series of watches. RGM debuted its “American Made” watches at the Geneva Time Exhibition, at the International Geneva Conference Centre (CICG) in Geneva, Switzerland, Sunday 16th to Friday 21st of January, 2011.

For the new Pennsylvania series case (Ref. 801) both the movements and the cases are made in Lancaster, PA. Now their American movement has an American case as well!

RGM continues to uphold the finest traditions of American horology by introducing the new Pennsylvania Tourbillon, their new flagship mechanical movement.

The Pennsylvania Tourbillon is the first serially produced American Tourbillon watch ever made. Following on the heels of America’s first high grade mechanical movement in four decades, the RGM Caliber 801 and Pennsylvania Tourbillon represent significant advances in domestic watchmaking. These watches are not only made in the U.S.A., but are created and built in Lancaster County, Pennsylvania; one of the few remaining traditional watchmaking centers of American watchmaking since the 1800′s.

Never before has an American watchmaker introduced a series of Tourbillon wristwatches based upon a proprietary caliber.

To do so, and to create them domestically, is an historic accomplishment.

The last time high-grade mechanical watch movements were produced in the United States was 1969– the year that Hamilton Watch Co. ended its period of more than 70 years of continuous manufacturing at its facility (just down the road from RGM’s current headquarters.).

When also designing the caliber 801, RGM wanted to create a watch that was reminiscent of American watches from the past; not only in its shapes, but in the quality of its construction. They wanted a watch that can stand the test of time and serve as a framework they can build upon when designing other functions.

The caliber 801 has very traditional hand finishing such as Perlage, Anglage, and Cote de Geneve waves on the bridges.

Another exciting feature of their Pennsylvania Series “American Made” watches is their new “Keystone Case” – 43mm of polished hand made stainless Steel, a rich coin edge, and powerful lugs.

In addition to the new Pennsylvania Tourbillon, RGM is already at work on variations of the new Caliber 801, such as the 24 Hour version (displayed at the GTE). They are also eager to soon share with the public another landmark creation at RGM, their Ladies watches.
