Strap for Multi-Scale Chronograph 4675 Rose Gold / 175th Anniversary

The lug width of the Patek Philippe Complications 4675R-001 is 20 millimetres. This dimension is determined by the case geometry and the position of the attachment pins. To verify compatibility, measure the distance between the centres of the two pins using a digital calliper, positioned parallel to the dial. No tolerance: 20 mm is the only compatible solution.

For the 4675R-001 in rose gold 18 carat, natural alligator with vegetable tanning is the classic choice for formal elegance. Shell cordovan represents a contemporary alternative with superior aesthetic evolution over time. For daily wear, vegetable-tanned calf offers a more natural patina, whilst NATO in heavy cotton ensures practicality without compromising proportions. The choice depends on context of use and personal aesthetic sensibility.

Strap replacement requires specialised tools: a thin flat-bladed screwdriver and a spring bar removal tool. Support the case gently, insert the screwdriver into the small lateral slot next to the pin and extract by pressing from bottom to top. For Patek Philippe watches with a 20 mm lug width, it is highly recommended to consult a specialist watchmaker to avoid scratching the case.

Any strap with a 20 millimetre lug width is theoretically compatible with the 4675R-001. However, to maintain aesthetic integrity and protect the rose gold case, it is advisable to choose superior quality straps: alligator, calf, shell cordovan or FKM rubber with refined finishes. Avoid generic or synthetic straps that could scratch the metal.

Durability depends on the quality of the leather and the context of use. Natural alligator and shell cordovan last 3–5 years with daily wear, developing aesthetic patina. Vegetable-tanned calf resists 2–4 years, whilst synthetic or economy straps have shorter lifespans. With regular maintenance (damp cleaning, drying, moisture protection), longevity can be extended. Casati Milano offers repair or replacement with an 18-month warranty on manufacturing defects.
