Pennsylvania Tourbillon

RGM Watch Pennsylvania Tourbillon

Here at RGM we are continuing to uphold the finest traditions of American horology by creating the Pennsylvania Tourbillon, our flagship mechanical movement made here in Lancaster County Pennsylvania. The Pennsylvania Tourbillon is signified by the state's symbol, a keystone, surrounding a capital T, which adorns the first serially produced American Tourbillon watches ever made.

The Pennsylvania Tourbillon is the fist serially produced Tourbillon in North America.  It is also a hand made watch with one of the largest Tourbillon cages for a watch that is 43.5 mm in diameter.  From it's Wolf's Tooth winding wheels, to its hand made Tourbillon cage it is a pure example of true watchmaking at its best.
