Rolex

The reference 6541 'Milgauss' was launched in 1956, designed as the embodiment of the Rolex ‘tool watch’ ethos. It was meticulously crafted to cater to a niche yet burgeoning clientele - scientists, engineers, and technicians immersed in environments saturated with high magnetic fields, be it in electro-industrial settings or scientific establishments. Its distinctive "lightning" seconds hand paid homage to the realm of electromagnetism. Notably, the Milgauss boasted a remarkable guarantee to withstand magnetic fields of up to 1,000 oersted.

The name Milgauss is derived from the Latin word ‘mille’, which means 1,000, and ‘gauss’, denoting the unit of magnetic field strength. To shield against magnetic interference, the Milgauss employed anti-magnetic alloys and an iron movement cover, ingeniously forming a Faraday cage - an impermeable enclosure designed to repel electrostatic and electromagnetic influences. Conveniently, Rolex had the opportunity to validate this breakthrough in close proximity to their headquarters, collaborating with scientists at the European Organization for Nuclear Research (CERN).

The Reference 6541 was created with an Oyster case and frequently sported a graduated rotating bezel, reminiscent of early Submariner references. However, Rolex also crafted a variant with a smooth bezel, as exemplified by the version showcased here - believed to have been made exclusively for the American market. The dial, constructed from layered copper, forms a webbed pattern, acting as a safeguard for the movement against magnetic forces. Collectors affectionately term this configuration a 'honeycomb' dial. For aficionados, the dial and its aging process hold paramount significance in any vintage Rolex. It encapsulates the essence of the watch, revealing its individuality and allure. The featured piece has aged gracefully, boasting a captivating tropical dial.
