The term “tool watch” is often used to describe Rolex timepieces, and is perfectly appropriate for the Milgauss which is the result of a direct collaboration between Rolex and Geneva-based CERN - Centre Européen de Recherche Nucléaire (European Organization for Nuclear Research). Their aim was to develop a wristwatch that could withstand intense magnetic fields and thus be worn by the CERN engineers and laboratory workers constantly in highly magnetic environments.

The result was the Milgauss, deriving its name from the Latin “mille” meaning a thousand, and “Gauss” representing the unit measure for magnetism. Accordingly, it could withstand exposure of up to 1000 Gauss with no effect on accuracy, whereas a typical watch movement can only withstand up to 70-90 Gauss. The reference 1019 of the present lot is Rolex’s second-generation Milgauss model, designed with a much smoother case compared with its predecessor.

The present watch is fitted with a black matte dial that permits the desirable red “Milgauss” text at 12 o’clock to stand out. This example is in exceptional original condition as it retains all its sharp edges and bevels. The Rolex sticker on the back suggests that this watch was rarely worn. Accompanied by its original guarantee, box and hangtag, it is a great find for the vintage tool watch aficionado.
