The Patek Philippe Nautilus (ref. 3800/1) in yellow gold with a black dial offers a rare blend of vintage sport design and precious-metal refinement. Introduced in the early 1980s as a mid-size alternative to the original 3700, the reference 3800 maintains the porthole-inspired case and horizontal ribbed dial that define Gérald Genta’s original concept but scales it to a discreet 37mm diameter.

Crafted entirely in 18k yellow gold, the case and integrated bracelet display fine satin brushing offset by polished bevels. The black dial – subtly glossy and marked with applied gold indices and a date at 3 o’clock – complements the warmth of the gold and underscores the piece’s late-century aesthetic. Inside, the in-house calibre 335 SC offers central seconds (a first for the Nautilus line at the time) along with a date complication and a power reserve of 45 hours. Water-resistant to 120m, it combines everyday resilience with unmistakable Patek elegance.

Long discontinued and increasingly sought after, the 3800/1 bridges early Nautilus heritage with wearability, offering collectors a rare full-gold configuration from the model’s formative years.
