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.
Only
140 examples of the
Patek Philippe ref.
1436 were ever made in the approximately
33 year production period from
1938 until it was discontinued in
1971.
This
Split-Seconds Chronograph is as
simple and pure aesthetically as it is
complex technically: “
simplexity”.

This
yellow gold example from
1965 is a
second gen. featuring a
co-axial push button within the crown for the split seconds function instead of the crown itself serving as a split button.

It is the
only known
watch of the reference to feature on its dial the
signature of the retailer
Gübelin of Lucerne.

The
case measures
33 mm diameter and the
watch was
sold by
Christie's in
2021 and before by
Antiquorum in
2003.

About the Patek Philippe Grand Complications Ref. 1436
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.

About the Patek Philippe Grand Complications Ref. 1938
The Patek Philippe Reference 1938 is a notable example of the brand's early rectangular timepieces, distinguished by its Art Deco design influences. While not as widely recognized as some later models, it represents a period of design exploration for Patek Philippe, particularly in non-circular case forms. Its aesthetic draws inspiration from earlier references such as the 514, 524, and 520, establishing a lineage of design principles that would evolve in subsequent collections. This reference is a testament to the brand's commitment to both horological precision and artistic expression during the interwar period.
This particular reference features a 30mm case crafted from a combination of platinum and rose gold, a sophisticated material pairing that enhances its visual appeal. It houses a manual-wind movement, specifically the 10''' lever escapement caliber, which was a common and reliable mechanism for its era. The dial is characterized by its three-color scheme, adding to the watch's distinctive Art Deco character. The fixed bezel integrates seamlessly with the case design, maintaining the watch's streamlined profile.
For collectors, the Reference 1938 offers insight into Patek Philippe's design trajectory in the early 20th century. Its unique case material combination and three-color dial make it a distinctive piece for those interested in the brand's historical design language. While it predates the more complex complications seen in later Patek Philippe watches, its aesthetic and mechanical integrity appeal to collectors focused on vintage design and the foundational elements of the brand's heritage.
