From Patek Philippe, presenting the Nautilus (ref. 3700/1A), a refined timepiece that blends thoughtful design with reliable performance. A study in proportion and durability: crafted in stainless steel and measuring 40 mm in diameter, with a thickness of 7.6 mm, defined by a cushion silhouette. The caseback is open, and the crystal is sapphire, delivering water resistance to 12000 meters. The dial composition is deliberate and legible: a blue tone, framed by stick / dot hour markers, and stick hands. Beneath the caseback lies dependable performance: the 28-255C caliber. Introduced in 19761982. Comfort and balance define the wearing experience, making it an easy daily companion. Subtle transitions between textures elevate the overall impression. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
