The steel First generation 2508 retailed by Astrua


Outstanding and exceedingly rare steel Rolex chronograph ref. 2508, manufactured in 1936.

Originally launched in the mid 1930s, reference 2508 most notably sports a large, masculine case with a classic “Calatrava” design.
It is amongst the most attractive chronograph models by any brand from this formative era of wristwatch design.

Reference 2508 can be categorized into two different generations: the first one - as the present example - boasting a large 37.2mm case fitted with olive-shape pushers. The second generation was slightly smaller measuring at 35.2mm and was fitted with rectangular pushers.
This 2mm difference in diameter may appear small, but the impact on the wrist is impressive.

Only a very small number of these first generation watches were made.

The present specimen stands out not only for its amazing condition but for the ultra rare presence of Turin retailer Astrua’s signature on the dial.

The amazing three-tone sector dial is preserved in absolutely original and untouched condition and it spreads an incredible charm thanks to its complicated architecture.
It features an outer blue telemeter scale and an inner spiral tachymeter case, large hour markers and an additional scale with Arabic five-minute combined with baton fifth-of-a-second divisions.

Moreover we can find a three different types of finishing: the centre and outer track of the dial are silvered brushed, the fifth-of-a-second scale lays on a track with a grené finish and a thin bronze metallic track separates it from the telemeter scale.
The blued tone of the hands gracefully gives an additional touch of color to the hole timepiece.

Definitely a unique opportunity to get one of the most rare, beautiful and emblematic Rolex vintage chronograph.
