"In response to your inquiry, we are pleased to provide you with a general report of the condition of the property described above. All dimensions in catalogue descriptions are approximate.

Watches in water-resistant cases have been opened to examine movements but no warranties are made that the watches are currently water-resistant. Please note that we do not guarantee the authenticity of any individual component parts, such as wheels, hands, crowns, crystals, screws, bracelets and leather bands, since subsequent repairs and restoration work may have resulted in the replacement of original parts. Since we are not professional conservators or restorers, we urge you to consult with a restorer or conservator of your choice who will be better able to provide a detailed, professional report. Prospective buyers should inspect each lot to satisfy themselves as to condition and must understand that any statement made by Sotheby's is merely a subjective, qualified opinion.

In 2005, the manufacture introduced the designation "Patek Philippe Advanced Research Limited Editions" and began to launch limited-edition wristwatches endowed with one or several avantgarde technologies.

The 500-watch edition of the reference 5650 Aquanaut Travel Time is the result of two important innovations created to improve long-term functional integrity. It has an optimized Spiromax® balance spring made of Silinvar® with patented terminal curve and inner boss that ensures greater precision within mechanical watches. The second innovation is a compliant mechanism crafted from conventional horological steel used to set the second time zone in time-zone watches.

This model features a blue dial embossed in the typical fashion and has an aperture at 9 o'clock through which the flexible mechanism with the four crossed leaf springs is clearly visible. In addition to these features, the reference 5650 includes displaying local time, local date, a second time zone, and a day/night indicator for both time zones.

This possibly unique Advanced Research sets itself apart from the other pieces produced because of the missing 53rd minute marker that can be seen just above the exposed part of the dial. This discrepancy has not been observed on any other dials of this already very limited series. The present lot is offered fresh to the market and from its original owner. It is accompanied by its full suite of accessories.
