The front of the Reference 57260.

To celebrate their 260th anniversary Vacheron Constantin have unveiled a true masterpiece of the watchmakers art. The one-of-a-kind reference 57260 (57 complications plus 260 years equals Reference 57260) is the most complicated watch ever made, and the latest in a long line of prestigious supercomplicated timepieces (like the recently sold Patek Philippe Henry Graves Jnr Supercomplication) dating back to Breguet himself. It’s a staggeringly impressive piece of engineering and art, and, to be honest it’s quite hard to comprehend the scale of the achievement. Beyond the challenge of understanding the functions of the watch, several of which are unique to this piece, there’s the bigger question of what this watch means for Vacheron Constantin, and the industry. It’s certainly one of the most important timepieces of the century.
