Strap for Annual Calendar 5146 Platinum / Grey

The Patek Philippe Complications 5146P-001 has a lug width of 20 mm, measured between the pins from inner shoulder to inner shoulder. This measurement is characteristic of Patek Philippe's Complications and Calatrava lines and requires careful attention when sourcing aftermarket straps to avoid incompatible sizes such as 22 mm.

For the platinum 5146P-001, the recommended materials are high-quality alligator (dark brown or black tones) and vegetable-tanned calf leather (dark colours or burgundy). Alligator offers sophisticated natural texture, whilst vegetable-tanned calf allows for elegant ageing patina. Both materials enhance the chromatic sobriety of the platinum case.

Strap replacement is accomplished by removing the pins with a specialised tool (spring bar tool). Since the 5146P-001 features tapered lugs, it is advisable to entrust the operation to a professional to prevent damage to the original pins or case. Casati Milano also offers strap-change services by appointment at the Milan atelier.

Any strap with a 20 mm lug width is compatible with the 5146P-001. MilanoStraps offers a dedicated collection of artisanal straps in alligator, calf, shell cordovan and other materials, all tested for the refined proportions of this Complications model.

A high-quality natural leather strap, whether vegetable-tanned or authentic alligator, guarantees an average lifespan of 3–5 years of daily use, depending on frequency of use and moisture conditions. MilanoStraps provides an 18-month warranty on manufacturing defects and offers restoration and replacement services through the Casati Milano atelier.
