Welcome to my Top Swiss Chronographs Boutique! Carl F. Bucherer is a Swiss watch company based in Lucerne, Switzerland, which manufactures luxury men's and women's mechanical watches. From its founding in 1888 until its sale in 2023, the company was wholly owned by the Bucherer family, making it one of the oldest luxury Swiss watchmakers continuously held by the founding family. The company was run by the original family's third generation, with Jörg G. Bucherer serving as chairman of the board. In August 2023, Bucherer AG was bought by Rolex. It will continue to trade under its own name and operate independently, and management will remain unchanged. The company will be integrated into Rolex's operations once the purchase is approved by competition authorities. The watch models of Carl F. Bucherer can be distinguished by certain functions including the chronograph, flyback, tachymeter, tourbillon as well as indicators and displays such as big date and day, power reserve, 24 hours, moon phases, three time zones, calendar, and perpetual calendar. Authentication: important to know! As of 2014, the company's manufacture movements have been protected against counterfeiting by special laser technology. Developed by the Swiss company Mimotec SA, the CLR-LIGA process imprints a unique signature on the surface of the watch movement using diffractive nano-structuring that can then only be authenticated with a specialized laser scanning device.
