Launched in 1981, the reference 3800 was Patek Philippe’s smaller iteration of the original Nautilus reference 3700. Measuring a still substantial 37.5mm diameter, the ref. 3800 is perhaps the perfect unisex wristwatch in modern times. The reference was manufactured with a wide array of case materials and dial variations, making it one of the most interesting luxury sports models manufactured by Patek Philippe to collect. Produced until 2006, the reference was launched in 4 series during its production spanning 25 years. The present 3800/3J belongs to the fourth and final series, featuring the ultra-thin, in-house caliber 330 194, which is marked by the Geneva seal and features a sweeping central seconds hand. Encased in yellow gold and fitted with a champagne ridged dial, this particular monochromatic iteration is extremely rare. Moreover, the diamond-set bezel and indexes add a subtle touch of elegance to the sports watch. Offered in like-new, hardly-worn condition and accompanied by its full set of accessories, the present Nautilus is sure to entice both male and female collectors of one of Mr. Gérald Genta’s most sought-after creations.
