Emmanuel, known as quattro on WatchProSite, presents an in-depth look at the Patek Philippe Ref. 1436 Split-Seconds Chronograph. His post highlights the rare 'simplexity' of this vintage reference, a term he uses to describe its aesthetic purity combined with technical complexity. This article delves into the specific details and historical context that make this particular reference a significant piece in Patek Philippe's horological legacy.







The Patek Philippe Reference 1436 is a split-seconds chronograph, a complication that allows for the timing of two separate events simultaneously or two intervals of a single event. This reference is notable for its relatively long production run and the variety of case materials in which it was offered, indicating its enduring appeal among collectors of complicated timepieces. It represents a significant example of Patek Philippe's early 20th-century chronograph production, preceding later, more complex multi-complication watches.
Crafted in 18k yellow gold, 18k rose gold, or platinum, the case measures 33mm in diameter. The watch is powered by a manual wind movement, the Caliber 13''', which is visible through the solid case back. The crystal protecting the dial is acrylic, a common material for watches of this era. The fixed bezel frames a silver dial, which often features applied hour markers and various scales depending on the specific execution.
This reference appeals to collectors seeking a classic split-seconds chronograph from a prominent manufacturer. Its variations in case material and dial configurations, including those with Breguet numerals or retailer signatures like Cartier, make individual examples highly sought after. The absence of a tachymeter scale on some versions further distinguishes them, highlighting the bespoke nature of certain commissions during its production period.
Thanks for posting it, Emmanuel.
So I'm afraid it will remain a dream. Thank you, Steve. Best, Emmanuel

That’s out of my budget 😂
It’s the Wendell Eads timepiece, a legend: www.watchprosite.com Best, Emmanuel
It was hard to give it back, even if I’m not necessarily a vintage guy, but those Breguet numerals…! I’m a sucker for Breguet numerals the way Patek does them!
