At the heart of this Calatrava lies Caliber 240, an ultra-thin self-winding mechanical movement that allows the 38 mm platinum case to sit at a remarkably slender 8.3 mm in height. A sapphire-crystal case back offers a view of the movement within, while water resistance to 30 m rounds out the case specification.
The dial is a work of hand engraving rendered in black enamel over an 18K gold dial plate — a combination that speaks to the meticulous craft traditions Patek Philippe brings to its most refined timepieces. Each engraved detail is executed by hand, giving the dial a depth and character that photography can only begin to convey.
Completing the watch is a shiny black alligator strap secured by a hand-engraved prong buckle, maintaining the artisanal theme from dial to wrist. Reference 5088-100P-001 is presented here as described, with the attributes listed above representing the full scope of confirmed specifications.
