Why this one
The case for this one.
- Stainless steel Nautilus case with the annual calendar and moonphase Patek reserves for its most technical sports references
- Charcoal sunburst dial paired with a black alligator strap and the original foldover clasp
- Full service history, ready to wear straight from the case
Patek Philippe folded the annual calendar into the Nautilus sports case with the 5726A, giving the collection's signature porthole silhouette a genuine complication instead of a simple date window. The charcoal dial carries day, date and month apertures across the top with a moonphase and 24 hour indicator below, all read at a glance under the embossed horizontal grain. This piece wears its stainless steel case and black alligator strap with the light, even polish of a watch that has been worn carefully and kept serviced.
