Patek Philippe Golden Ellipse 40th Anniversary

The Patek Philippe reference 3700 is recognized as the original Nautilus model. It established the distinctive porthole-inspired case design and integrated bracelet that define the collection. This reference was produced for a significant period, laying the foundation for subsequent Nautilus iterations and solidifying its place in the brand's sports watch offerings.

This reference features a stainless steel case measuring 42 mm in diameter and 7.6 mm in thickness, fitted with a sapphire crystal. It houses the self-winding Caliber 28-20 C, which provides a power reserve of 45 hours. The watch is water-resistant to 120 meters and typically presents with a blue dial, offering a date complication.

The 3700 appeals to collectors interested in the foundational pieces of significant watch lines. It represents the initial vision for the Nautilus, preceding later mid-size and complicated versions. Its production run from 1976 to 1990 saw various dial and bracelet configurations, making specific examples of interest to those studying the model's evolution.

The Nautilus reference 3700/1A represents the original iteration of Patek Philippe's sport watch, introduced in 1976. This reference established the distinctive porthole-inspired case design and integrated bracelet that would become synonymous with the Nautilus line. It was initially marketed as a luxury sport watch, distinguished by its steel construction at a time when most high-end watches were crafted from precious metals. The 3700/1A set the foundation for all subsequent Nautilus models, defining its aesthetic and functional identity within the brand's offerings.

The watch features a monobloc case construction, meaning the movement is loaded from the front, with a screw-down bezel securing the crystal. The case material is stainless steel, and it houses an automatic movement. The original Nautilus was notable for its relatively thin profile for an automatic watch of its era. The integrated bracelet, also in stainless steel, was an integral part of the design, ensuring a seamless transition from case to wrist.

This reference is highly significant for collectors as the progenitor of the Nautilus family. Its historical importance as the very first Nautilus makes it a cornerstone piece for any serious collection focusing on the evolution of luxury sport watches. The 3700/1A was produced in several dial variations over its production run, with subtle differences in dial text and color contributing to its collectibility.
