DIAM. 36 mm. THICKNESS 12 mm. It is rare that an unknown reference surfaces especially in Rolex chronographs, but this example illustrates this perfectly. Discovered recently in Switzerland (which makes sense considering it is retailed by C. Bucherer), this reference 2562 is not found in any literature. Part of the family of early Rolex chronographs it features the often found dials featuring the spiral tachometer scale in the center but unusually features a large steel bezel. Measuring in at a nice 36mm.and an untouched original patinated dial, it has never been seen at auction before.
