Rolex, Ref. 2508 Antimagnetic (or Anti-Magnetique)

The reference 2508 was first produced in the mid 1930’s, in 18K yellow or pink gold and in stainless steel non-waterproof cases, with olive-shaped push-buttons (oval pushers), a 14’’’ movement and a diameter of 38 mm. (37.2 mm. to).

After that, it was made with rectangular push-buttons (square pushers), a 13’’’ movement and a 2 mm. smaller case of 36 mm. (35.2 mm. to).

Early 2508’s had the serial numbers punched on the case-back, whereas the last generation had the 6 digits number finely engraved at the edge of the back.

This is the first Rolex chronograph wristwatch to feature two registers on the dial and two pushers in the case.

The sporty and large case is very masculine, and is considered one of the most attractive case designs by any brand of this era. At the time of production, the relatively large case size was incredibly unusual for the period. This reference is a favourite amongst collectors due to its oversized case, flat bezel, and classic no frills design, that is more in-line with those of two other historical Genevan brands: Patek Philippe and Vacheron Constantin.
