ETA SA ATELIER-621-1788

The ATELIER-621-1788 is a manual-winding movement manufactured by ETA SA, based on the Swiss 6498 architecture and heavily modified with proprietary components. It features 17 jewels and Incabloc shock protection. The movement is manufactured, built, regulated, and finished in the United States by 1776 Atelier, incorporating a proprietary three-quarter bridge and a main plate reduced by just over 1mm in diameter. It serves as the foundation for two of the brand's inaugural collections.
