Nikos Koklonis spotted wearing a Patek Philippe

Greek television and entertainment personality Nikos Koklonis was spotted wearing the Patek Philippe Aquanaut Ref. 5821/1A during a recent public appearance in Athens. The timepiece, worn on the wrist in the photograph, displays Patek Philippe's signature integrated stainless steel bracelet and distinctive tonneau case geometry that defines the Aquanaut line since its 1997 inception.

The Ref. 5821/1A is powered by the Patek Philippe caliber 26-330 S C, an automatic movement with 40-hour power reserve and chronometer-grade accuracy. The case measures 42.2 mm in diameter and 10.7 mm in thickness, constructed entirely from stainless steel with a screw-down crown rated to 300 meters water resistance. The dial features horizontal integrated lines in an olive green colorway—a departure from traditional blues and grays that has resonated strongly with collectors seeking contemporary sportwatch aesthetics. The integrated bracelet employs solid links with a diving extension allowing wear over a wetsuit.

Introduced in 2023, the Ref. 5821/1A marked a significant evolution for Patek Philippe's sports line, as the previous Aquanaut generation (Ref. 5167/1A) remained largely unchanged since 2006. The larger case diameter, updated movement finishing, and modern dial options—particularly the olive green variant—generated considerable collector demand upon release. This reference occupies the middle ground between the entry-level Nautilus and professional-grade Aquanaut Sport models, making it highly visible among luxury watch enthusiasts.

Koklonis, known within Greek entertainment circles for an interest in fine timepieces and distinctive personal style, selected the olive green Aquanaut at a moment when the reference commands significant grey-market premiums. The pairing reflects broader collector trends toward contemporary dial colors on classic integrated-bracelet sports watches.

Retail pricing for the Patek Philippe Aquanaut Ref. 5821/1A begins at approximately USD 36,450. However, strong demand has pushed grey-market pricing to USD 42,000–48,000 depending on condition and availability. At authorized dealers, waitlists for this reference typically extend 12–18 months, underscoring its desirability within the current Patek Philippe sports collection.
