Baume& Mercier William Baume Single Push-Piece Chronograph

A complication that is both useful and aesthetically pleasing, the single push-piece chronograph serves to start, stop and reset short times by pressing a single pusher. It thereby also streamlines the aesthetic of the case side by integrating the crown and two pushers into a single element, compared with three separate elements on conventional chronographs.


This newcomer to the William Baume collection derives its historical legitimacy from a wristwatch with a single push-piece chronograph function introduced by Baume & Mercier in 1938. Entirely in tune with the contemporary design of the William Baume line, the silvered dial of the new model reflects the two horizontal counters of the original: the small seconds counter at 9 o’clock and the chronograph minute at 3 o’clock.

The chronograph seconds are read off as usual by the central hand. The silvered dial is adorned with a “Vieux Panier” guilloché décor and a sun satin-finish on the rings surrounding the chronograph counters and the chapter ring. The mechanical hand-wound movement, with its circular-grained mainplate, bridges graced with “Côtes de Genève” and blued steel screws, can be admired through a broad sapphire crystal window in the case-back. The 18K red gold XL-sized (41 mm) case is teamed with a hand-stitched chestnut brown alligator strap. Limited, numbered edition of 20 watches.
