Housed in a 41mm cushion-shaped stainless steel case, this Nautilus reference 5726/1A-014 pairs a smooth fixed bezel with a screw-down crown and a scratch-resistant sapphire crystal. The stainless steel bracelet secures with a fold-over clasp, and the watch carries a Swiss Made designation with water resistance rated to 10 ATM.
The blue dial is appointed with luminescent silver-tone hands and luminous index hour markers for reliable legibility. A full suite of calendar functions is displayed across the dial: date at 6 o'clock, day and month at 12 o'clock, and a moon phase complication, all driven by an automatic movement.
This example is offered complete with its original box and papers, representing one of Patek Philippe's most compelling sport-complication references for the discerning collector.
