The strap execution of the anniversary Nautilus: 41mm white gold on leather rather than an integrated bracelet, the same horizontally embossed sunburst blue dial, here with baguette-cut diamond hour markers. A 1,000-piece edition — half the run of the bracelet reference. What matters on examination: the setting of the baguette markers, and whether any stone has been disturbed or replaced; original case geometry and finishing; and complete documentation, which on a stone-set anniversary reference should carry the original stone specification. Confirmed through the desk. Maker: Patek Philippe. Reference: 5810G-001. Available through ELITA's private desk — verification review, discreet handling and storage. Price on request.
