Valjoux 22 manual-winding movement. Steel case, 35 mm diameter, rectangular pushers, snap-on case back. Silver dial with two sub-dials — small seconds at 9, 30-minute register at 3 —, applied gold Arabic numerals, polychrome telemeter and tachymeter scales. Plexiglas crystal. Rolex steel Oyster bracelet and signed deployant clasp.\u003c\/p\u003e\n\u003ch3\u003eHorological context\u003c\/h3\u003e\n\u003cp\u003eThe reference 2508 ranks among the first series-produced wristwatch chronographs made by Rolex, manufactured from the late 1930s to the mid-1940s. It introduced the two-register, twin-pusher layout that would become the Rolex chronograph standard, long before the \u003cem\u003eCosmograph Daytona\u003c\/em\u003e name appeared. Its case does not yet adopt the waterproof Oyster architecture: the \u003cem\u003eAnti-Magnetic\u003c\/em\u003e signature on the dial reflects the \u003cem\u003emaison\u003c\/em\u003e's research into protecting the movement. The Valjoux 22 calibre, a column-wheel chronograph valued for its reliability, powers most 2508s. Produced in limited numbers and offered with a wide diversity of dials, the reference holds a sought-after place in the history of the earliest Rolex chronographs.\u003c\/p\u003e\n\u003ch3\u003eCharacter\u003c\/h3\u003e\n\u003cp\u003eOriginal dial with pronounced patina and old, stabilised moisture spots.\u003c\/p\u003e\n\u003cp\u003eServiced watch.
