Strap for Sky Moon Tourbillon 6002 White Gold / Black

The lug width of the Patek Philippe Grand Complications 6002G-010 is 18 mm. This measurement must be taken between the inside surfaces of the two spring bar holes (the horizontal pins that secure the strap to the case). Precise measurement with a digital calliper is essential to ensure the strap fits perfectly without play, as even half a millimetre of deviation can compromise the fit in the case lugs.

For this white gold masterpiece, alligator remains the most elegant and versatile choice, thanks to its natural geometric texture and the patina that evolves over time. If you seek drama and chromatic depth, shell cordovan delivers an intimate sheen and exceptional colour richness. Vegetable-tanned calf leather offers a more tactile alternative, particularly in cognac or dark brown tones. For summer use or humid environments, a high-quality vegetable rubber strap ensures protection without aesthetic compromise. Ideally, own at least three straps: one in alligator for formal occasions, one in cordovan for refined daily use, and one in rubber for casual contexts.

Changing the strap on the 6002G-010 requires a specialised spring bar tool for extracting the pin lugs. Using a pressure spring or spring bar removal tool, insert the tip under the lug from the inside of the case, apply gentle outward pressure to release the internal spring, and slide the pin out. Repeat on the other side. Position the new strap by aligning the holes with the lugs, and press until the spring clicks back into place. If you are uncertain, entrust the operation to a qualified watchmaker: an improper grip could scratch the gold case.

Yes, any strap with an 18 mm lug width is theoretically compatible with the Patek Philippe Grand Complications 6002G-010. However, given the rarity and monumental value of this timepiece, it is essential to select an artisanal strap of the highest quality, where leather, finishing, and construction respect Patek Philippe standards. Generic or industrial straps diminish the aesthetic identity of the watch. On milanostraps.it, you will find 18 mm straps crafted from premium leathers (alligator, cordovan, calf), built according to the finest artisanal traditions, and guaranteed for 18 months against manufacturing defects.

The lifespan of a leather strap depends on wear frequency, leather type, and exposure conditions. A high-quality alligator or cordovan strap, if worn regularly on a watch used 2–3 times per week, typically lasts 3–5 years before showing significant wear signs (peeling, cracking at the lugs). Vegetable-tanned leather, more porous and lively, may age faster but also more elegantly, developing a fascinating patina. Humidity, excessive heat, and sun exposure accelerate ageing. Rotating between multiple straps (as recommended for a Patek Philippe) allows each strap to rest between uses, significantly extending longevity. Casati Milano straps, thanks to leather selection and artisanal construction, are guaranteed for 18 months against manufacturing defects, yet with proper care easily exceed 4–6 years of useful life.
