Nautilus 3800/1JA — Two Tone (1984)
A beautifully preserved example of one of the most elegant Nautilus references ever created.
The Nautilus Ref. 3800/1JA represents the refined, mid-size evolution of the iconic Nautilus line. Introduced as the successor to the larger 3700, the 3800 brought the Gérald Genta design to a broader audience — retaining its unmistakable silhouette while offering a more versatile 37.5 mm size.
This example stands out with its rare two-tone construction in stainless steel and 18k yellow gold. The golden ribbed sigma dial is untouched and flawless, complemented by evenly aged original lume that adds warmth and character. The slim 7.4 mm profile, integrated bracelet, and monobloc case architecture make this Nautilus exceptionally comfortable and visually harmonious.
Powered by the ultra-thin automatic Caliber 335 SC, the watch delivers precision inside a case that remains sleek and timeless.
A superb piece for collectors seeking an early two-tone Nautilus in top condition.
