Patek Philippe 5370P Split Seconds Chronograph Platinum Blue Enamel Dial

Introduced in 2020, the Patek Philippe 5370P‑011 Split‑Seconds Chronograph in platinum with a Grand Feu blue enamel dial represents a masterful evolution of the 2015 black‑dial original. Crafted in 950 platinum, its 41 mm case features a concave bezel, satin‑finished flanks, and the signature small diamond between the lugs at 6 o’clock, while offering both sapphire display and solid case backs. Inside resides the in‑house caliber CHR 29‑535 PS, a manually wound split‑seconds chronograph movement with dual column wheels, horizontal clutch, instantaneous 30‑minute counter, and a 65‑hour power reserve at 4 Hz. The glossy blue Grand Feu enamel dial, set on an 18 K gold plate, is adorned with applied white‑gold Breguet numerals, leaf‑shaped hands with luminescent coating, and a tachymeter scale—an exquisite blend of technical prowess and artisanal artistry. Paired with a hand‑stitched shiny dusk blue alligator strap and platinum fold‑over clasp, the watch remains water‑resistant to 30 meters. Though not a limited edition, the 5370P‑011 is produced in very low quantities and holds a revered place among modern Patek Philippe collectors as the first split‑chronograph‑only wristwatch since the legendary Ref. 1436. Like New with Patek Philippe box, additional solid caseback, and papers dated 2021.
