Strap for Annual Calendar 4946 Stainless Steel / Blue

The lug width of the Patek Philippe Complications 4946R-001 is 18 millimetres. This measurement represents the space where the strap attaches to the case. It is critical to choose a strap of exactly 18mm to avoid visible gaps between the terminal and strap, or overlaps that compromise aesthetics.

For this rose gold model on a 38mm case, alligator remains the traditional choice: its natural grain pattern dialogues perfectly with the case elegance. Alternatively, vegetable-tanned calf offers a patina that develops over time, or shell cordovan for those seeking character and inherent lustre. All available in 18mm lug width.

Changing the strap requires the use of a precision tool (spring bar tool) to extract the spring bars from the case terminals. It is recommended to consult a qualified watchmaker or artisanal atelier such as Casati Milano to avoid scratches on the rose gold case, which is particularly precious.

Yes, high-quality artisanal straps in 18mm lug width are available, compatible with the 4946R-001. You can choose from alligator, calf, shell cordovan and other premium materials directly on milanostraps.it. Casati Milano also offers an atelier service where you personally select the leather with an 18-month manufacturing defect warranty.

The lifespan of a leather strap depends on usage, humidity and material quality. On average, an artisanal alligator or calf strap lasts 3-5 years with regular wear. Shell cordovan, owing to its superior resistance, can last 5-7 years. Vegetable-tanned leather develops a patina but remains functional beyond 5 years. Regular maintenance and appropriate storage when the watch is not worn significantly extends useful life.
