Launched in 1981, the reference 3800 was Patek Philippe’s iteration of the original Nautilus ref. 3700, in a slightly smaller case. Measuring 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. Manufactured until 2006, the reference was launched in four series during its lengthy production spanning 25 years.

The 3800/2 differs slightly from the 3800 with the presence of diamonds set to the external edge of the bezel. A more subtle touch of elegance and luxury than the more commonly seen single or triple row of diamonds to the bezel, it is an extremely rare iteration of the mid-size Nautilus, as this is the first ever example in this combination to come to market. The present, fresh-to-the-market example, with a diamond-set deep navy dial, is in exceptionally well-preserved condition with crisp bevels, sharp hallmarks to the caseback, and a tight bracelet.
