The present Patek Philippe Aquanaut reference 5066, dating to 1998, is an excellent and highly appealing example of one of Patek Philippe’s most influential modern sports watches. Offered as a complete full set and coming directly from its original owner, this watch combines strong provenance with recent factory service. The watch was fully serviced by Patek Philippe in 2022, during which the hands were replaced. It is therefore fitted with luminova service hands, while the original tritium dial remains beautifully preserved, creating a typical and honest configuration for a well-maintained Aquanaut of this period. The dial is in excellent condition, retaining its clean, crisp appearance and original character. The stainless-steel case has been professionally polished by our watchmaker and now presents in top overall condition, with sharp lines and a fresh, attractive appearance. Mechanically, the watch is in perfect working order following the recent Patek Philippe service, ensuring reliability and immediate wearability. Accompanied by its full original set of accessories, this Aquanaut 5066 represents a compelling opportunity to acquire a classic late-1990s Patek Philippe sports watch with documented maintenance, single-owner provenance, and excellent overall presentation.
