勞力士，精細及罕有，不銹鋼腕錶，配計時功能，“Antimagnetic”，型號2508，由Rösch Berne銷售，約1935年製

Reference 2508 was introduced into the market in the mid-1930s. The first generation featured oval chronograph buttons, whereas the second series were fitted with rectangular pushers, such as the present watch. This particular watch is unusual due to the retailer signature of W. Rӧsch, Berne applied to the dial and its appealing overall patina.
