1970s BWC Chronograph (Ref. 953013) "Valjox Cal. 7733"

Founded in Buttes, Switzerland by Arthur Charlet in 1924, Buttes Watch Company - better known as BWC - is one of the many Swiss timepiece brands that flourished before the Quartz Crisis in the 1970s. Although BWC produced a wide variety of different watches including early electronic models during the 1950s and even quartz timepieces during the later part of the 1970s, the brand is best known for its mechanical sports chronographs that often feature funky case shapes and colorful dials.   

Models like this BWC chronograph ref. 953013 are excellent examples of the timepieces that the brand produced during the golden era of the mechanical wristwatch. Featuring a circular dial set into a square case and surrounded by a bezel with both tachymeter and telemeter scales, this BWC chronograph offers distinct 1970s styling with the proven performance of a manually-wound Valjoux 7733 movement.
