Introduced in 2015 with a platinum case and a Grand Feu black enamel dial (ref. 5370-001), Patek Philippe's Split Seconds Chronograph ref. 5370 now comes in a rose gold case with a Grand Feu brown & beige enamel dial (ref. 5370R-001).

It replaces in the catalog the 2020 variant, which came with a platinum case with a Grand Feu blue enamel dial (ref. 5370P-011).

The case measures 41 x 13,56 mm and the watch is powered by manual wind caliber CHR 29-535 PS.

The three models are presented here in reverse chronological order.

Best,

Emmanuel

Key Points from the Discussion

The new 2025 Ref. 5370R-001 in rose gold with a vintage-inspired brown & beige enamel dial is considered by some to be the most beautiful iteration, evoking strong emotional appeal despite its high price point.
A key debate revolves around the thickness of the Ref. 5370. While some find the platinum versions top-heavy, especially for a dress watch, others, like the original author, appreciate the depth of the caliber, such as the Laurent Ferrier micro-rotor, even if it results in a slightly thicker profile.
The blue enamel dial of the 2020 Ref. 5370P-011 is highly praised, with some collectors considering it to elevate the watch to 'another level' of beauty, while acknowledging the warmth and inviting aesthetic of the new rose gold version.
The original author expresses a personal preference for colored gold cases, finding their warmth more attractive than the 'colder' tones of platinum or white gold, which influences his appreciation for the new rose gold Ref. 5370R-001.
One contributor shared a personal photo of the new Ref. 5370R-001, emphasizing the 'amazing' metal and its visual impact.

..super nice. But why isn't Patek making thinner movements? The 5950A posted recently is only 10.15 thick.
