Breguet Type XX 3800 Collection

The Patek Philippe reference 3800, introduced in 1981 and available from 1982, represents a significant evolution of the Nautilus line. Positioned as a mid-size alternative to the original reference 3700, it offered a more versatile wearing experience while retaining the distinctive porthole-inspired case design. This reference was notable for being the first Nautilus to feature an in-house automatic movement, marking a shift in Patek Philippe's manufacturing strategy for the model. It was produced until 2006, allowing for a wide array of material and dial variations over its production run.

The case of the reference 3800 measures 37.5 mm in diameter, a reduction from the larger 3700. It was produced in various metals, including stainless steel, yellow gold, rose gold, white gold, and platinum, often paired with integrated bracelets or leather straps. The watch is powered by the in-house automatic caliber 330 SC, which features a central rotor and provides a power reserve of approximately 48 hours. A sapphire crystal protects the dial, and the watch offers water resistance suitable for daily wear.

For collectors, the reference 3800 appeals to those seeking a more understated and wearable Nautilus compared to its larger predecessor. Its long production period resulted in numerous dial configurations, including black, blue, and white, with different hour marker styles. The 3800/1A-001 and 3800/1A-XII are specific stainless steel variants that highlight the model's enduring appeal in its original material. Its status as the first Nautilus with an in-house movement also adds to its historical importance within the brand's catalog.
