Raymond Weil RW4100

The RW4100 is a manual-winding mechanical movement manufactured by Raymond Weil in Switzerland. Based on the Sellita SW210-1, it operates at 28,800 vph with an approximate 45-hour power reserve and 18 jewels protected by an Incabloc shock absorber. The finishing varies between Sellita's Refined and Tailor-Made options, typically including Geneva stripes, circular graining, snailed crown-wheel and ratchet, and rhodium plating. The movement is currently in production and used in the Toccata Heritage collection.
