Reference 5104P-001 belongs to the Grand Complications family, presenting a 43 mm case and matching bezel crafted entirely in platinum. The skeleton dial strips away every surface that is not strictly necessary, drawing the eye directly into the gear train and the complications within — a format that demands as much from the finisher as it does from the engineer.
A screw-locked crown and sapphire crystal front the case, while the transparent sapphire case back provides an unobstructed second vantage point onto the movement. Power comes from an automatic caliber, and a platinum folding clasp secures the leather strap at the wrist. Water resistance is rated to 30 meters.
This example is offered as a complete set with its original box and papers. The platinum construction, openworked dial, and full set presentation make the 5104P-001 one of the more sought-after expressions within Patek Philippe's Grand Complications catalogue.
