Patek Philippe Nautilus Blue Sigma Dial 18K Yellow Gold Patek Philippe Service 2020 Ref 3800 from 1990

An exceptional Patek Philippe Nautilus in solid 18k yellow gold, produced in 1990 and featuring a beautiful original blue Sigma dial. Combining the unmistakable Gérald Genta Nautilus design with the warmth and presence of full yellow gold, this is a rare and powerful expression of Patek Philippe’s legendary luxury sports watch.

The watch is preserved in excellent overall condition, with a strong and sharp case retaining clearly defined hallmarks. Its integrated 18k yellow gold bracelet measures approximately 18 cm and remains exceptionally strong, showing no notable signs of stretch.

The highlight is the attractive original Patek Philippe blue Sigma dial, which provides a wonderful contrast against the yellow gold case and bracelet. The dial remains beautifully preserved and is protected by a sapphire crystal.

Inside beats the Patek Philippe Calibre 335 SC automatic movement. The watch is accompanied by Patek Philippe service documentation from 2020, providing valuable documented service history.

Also included is additional Patek Philippe paperwork and a Patek Philippe travel box. Please note that the watch does not come with its original sales invoice or warranty certificate.

No Extract from the Archives is included, as Patek Philippe did not provide one for this watch. A possible explanation could be a movement replacement during a previous Patek Philippe service, although this cannot be confirmed and should therefore be considered only a possibility.
