Patek Philippe held the record for most complicated watch for more than a quarter of a century, but now Swiss manufacturer Vacheron Constantin has revealed the Reference 57260 and taken the coveted top spot.

In development for 8 years, the new pocket watch was created in celebration of the brand’s 260th anniversary and features 57 complications, beating Patek Philippe Calibre 89’s record of 33.

The 18-karat white-gold, dual-dialed watch includes unique additions like a star chart, a regulator-style timekeeping display, and a moon-phase indicator. Vacheron Constantin’s new watch also accounts for leap year and indicates the Gregorian date of each Yom Kippur.

Even more unique, the Reference sports a double retrograde split-second chronograph, which means the hands rotate in opposite directions before snapping back to their starting position after completing a 60-second cycle.

The world’s newest most complicated watch has a slew of additional features—including a 12-hour second time-zone display and a night mode which disables gong strikes—but it’s also stunning with a classic design.

It’s rumored that the new timepiece sold for $8 million.
