Patek Philippe Ellipse Deco Collection Overview

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 Patek Philippe Golden Ellipse reference 5738 represents the white gold iteration of the model with a blue dial configuration. This reference distinguishes itself within the Golden Ellipse range through its precious metal case construction and contrasting dial treatment, positioning it among Patek Philippe's dress watch offerings.
