A refreshingly different pick from the era when horology was forced to be technical and creative in the face of competition from the quartz phenomenon. This self-winding Breitling from 1971 is powered by the Calibre 12, effectively the world's first self-winding chronograph movement (don't believe the 'El Primero' hype...). 

Oriented vertically so that the Chronograph pushers thrust up like horns, the bullhead is a stylistic icon of its era – Breitling being believed to have been the first to come up with this layout. The slightly sloped case (like a vintage writing table) was inspiration for the official name "Pult Pupitre".

Correct upright calendar disc, superb condition dial with tritium markers and skeleton hands (with the chrono hands in day-glo orange), and a practically perfect anodised bezel.

Rare and iconic, it's become very difficult to find truly interesting watches now at sensible prices amid the power of the mainstream.
