The Patek Philippe reference 3738 is one of the defining models of the Golden Ellipse collection, embodying the understated elegance that has characterised the family since its introduction in 1968. Powered by the ultra-thin automatic Calibre 240 with micro-rotor, the 3738 combines exceptional mechanical refinement with the distinctive elliptical case inspired by the Golden Ratio. Its minimalist dial, slender baton hour markers and beautifully balanced proportions reflect Patek Philippe's philosophy that true luxury is expressed through harmony, restraint and timeless design rather than unnecessary ornamentation.

Produced in a variety of precious metals, including yellow gold, white gold and rose gold, the reference 3738 remained in production for many years, becoming one of the most recognisable Golden Ellipse references of the modern era. Its ultra-thin movement, elegant profile and exceptional finishing made it a favourite among collectors seeking a sophisticated dress watch outside the traditional Calatrava collection. Today, the 3738 is regarded as the direct predecessor to the modern reference 5738, preserving the enduring appeal of the Golden Ellipse while laying the foundation for its contemporary evolution.
