Entrepreneur Nikos Oikonomopoulos spotted wearing a Patek Philippe

During a recent trip to Mykonos, Greek entrepreneur and hotelier Nikos Oikonomopoulos drew considerable attention at the upscale Aroma bar in Matogiannia while wearing an exceptionally rare Patek Philippe Aquanaut Luce Annual Calendar Ref. 5650G. The timepiece, acquired from noted watch collector Manos Kartsonakis, exemplifies the intersection of sport-utility design and haute horlogerie that defines Patek Philippe's most coveted contemporary references.

The Ref. 5650G houses the Calibre 5650 automatic movement, a sophisticated self-winding mechanism featuring the annual calendar complication—a refinement that requires date adjustment only once annually, on March 1st. The 42 mm white gold case maintains the iconic Aquanaut rounded-square silhouette introduced in 1997, while the sunburst blue dial displays sub-dials for the annual calendar, moon phase, and day-of-week indication. The watch carries 300 metres of water resistance and arrives on a blue rubber strap, reinforcing its dual nature as both practical dive instrument and refined dress complication.

The annual calendar complication remains among the most technically accomplished yet user-friendly perpetual date mechanisms in watchmaking. Unlike a true perpetual calendar (which accounts for leap years), the annual calendar simplifies maintenance while delivering practical utility—a philosophy consistent with Patek Philippe's engineering ethos. The Ref. 5650G arrived in limited production quantities following its introduction and has maintained scarcity in the secondary market, with relatively few examples in white gold circulating among collectors.

Oikonomopoulos's choice reflects the preferences of discerning Greek collectors and entrepreneurs who favour complications-driven sports watches. The pairing of white gold with blue dial and rubber strap remains one of the most visually balanced configurations of the reference, balancing formality with contemporary ease. His acquisition from Kartsonakis, a respected figure in European watch circles, underscores the watch's standing among serious collectors.

Retail pricing for the Aquanaut Luce Annual Calendar Ref. 5650G in white gold sits substantially above entry-level Aquanaut models, reflecting the annual calendar mechanism's exclusivity. Secondary market examples command premiums, with grey-market availability extremely limited and waiting lists at authorized Patek Philippe retailers measured in years. The reference represents a more accessible entry point to annual calendar complications than Patek Philippe's Perpetual Calendar models, yet maintains the prestige and technical depth expected of the manufacture.
