Patek Philippe 5204G-010 Split-Seconds Chronograph Perpetual Calendar 40mm White Gold Watch

Patek Philippe 5204G-010 Split-Seconds Chronograph Perpetual Calendar 40mm White Gold Watch

The Patek Philippe 5204G-010 combines two of watchmaking’s most demanding complications in a single 40mm white gold case — the split-seconds chronograph and the perpetual calendar. This 2026 iteration introduces a navy blue sunburst dial and sportier blue composite strap, giving one of Patek’s most technically accomplished references a more contemporary, wearable character without compromising a single element of its mechanical depth.

Split-Seconds Chronograph — The Ultimate Timing Tool

The split-seconds chronograph — known as the rattrapante — adds a second chronograph hand that can be stopped independently of the first, allowing the timing of two simultaneous events. It is one of the most mechanically complex chronograph complications, requiring a highly sophisticated additional mechanism that engages and releases the split-seconds hand with precise, spring-loaded control. The Calibre CHR 29-535 PS Q is among the most respected chronograph movements in existence — a movement that Patek Philippe has refined over decades.

Perpetual Calendar — Mechanical Intelligence

Alongside the split-seconds mechanism, the 5204G-010 houses a complete perpetual calendar — displaying the day, date, month, leap year, and moonphase, all adjusted automatically for the varying lengths of every month until 2100. The combination of these two complications in a 40mm case is a feat of miniaturisation that only a handful of manufacturers in the world can achieve.
