The world’s most complicated watch: Vacheron Constantin Ref. 57260


Your brain is going to hurt just reading about the many, (so many) complications packed into what has been declared by Vacheron Constantin as the most complicated timepiece ever made. It tops the Supercomplication specially made by Patek Philippe in between the two world wars for multi-millionaire Henry Graves Jr. That watch recently sold at auction for $24 million.

The Vacheron Constantin Reference 57260 was made specifically for a private and anonymous client. It took three of Vacheron Constantin’s top watchmakers more than eight years to create. As the 57 in the reference number suggests, the watch has 57 distinct complications packed into a 98 mm by 50.55 mm thick solid 18k white gold case. While it looks like a pocket watch it’s simply too bulky (and too risky) to consider carrying it in your pocket. The 2,800-component Reference 57260 was built entirely from scratch.

The complications include multiple calendars and a double retrograde rattrapante chronograph, something which had never previously existed and therefore had to be calculated, designed and developed from scratch, thereby requiring a completely new movement. Even the mechanisms of the more familiar complications have been modified, reinterpreted and redesigned so that the finished watch is harmonious as a whole.


The 57260 runs on a 242 jewel Caliber 3750 movement that operates at a frequency of 2.5 Hz and has a 60-hour power reserve. The movement features the company’s Maltese cross trademark and the famous motto conceived by co-founder Jean Marc Vacheron:  “Faire mieux si possible ce qui est toujours possible” (“Do better if possible and it is always possible”).

The 57 complications of the piece embrace everything from simple time keeping to astronomy to extremely complex calendars along with some impressive bespoke features never before created for a watch.

Considering the number of major complications on display, the front and back dials of the Reference 57260 watch have a display that is exceptionally easy to read. That said, the watch comes with a comprehensive chart to help the owner understand the workings of the complications more fully.

The pushbuttons on the white gold case are discreetly integrated into its middle. The alarm winding crown maintains the clean lines of the elegant case, becoming invisible through a sophisticated concealment system.
The 2,800 parts were all completely hand-decorated by one single Master Watchmaker, using traditional techniques such as bevelling, circular graining, the “Côtes de Genève” decoration, and more.

The excellence of Vacheron Constantin is apparent in the entire finished work of the Reference 57260 watch, in full accordance with the Hallmark of Geneva. The price of the timepiece has not been disclosed, but it is likely to be upwards of $5 million. For those that wish to know everything about the 57260, Vacheron Constantin have created a micro website  which has an extensive overview of the watch.
