The Mondaine SBB, introduced in 1986, is the Official Swiss Railways Watch. It has a plain white dial with black hour and minute markers and hands, and a red seconds hand ending in a disc, copying the station clocks designed by Hans Hilfiker for the Swiss Federal Railways (SBB) in 1944. The watch is quartz and the case is steel, with a simple leather strap; the Classic range comes in several diameters, so I have not stated a single size.

The red disc is meant to copy the signal paddle used by station staff, and the clock’s second hand pauses briefly at the top of each minute while it waits for the next. Mondaine licensed the design from the SBB and has made it its core product.

The watch is widely seen as a design classic, in the same spirit as the Bauhaus-style Swiss designs, and as an affordable one. It remains in production as the Mondaine Classic and Evo ranges.
