Strap for Annual Calendar 5205 White Gold / Blue

The lug width of the Patek Philippe Complications 5205G-013 is 20 millimetres. This measurement must be strictly observed when selecting any aftermarket strap: straps designed for 18mm or 22mm lugs will not sit properly. The measurement should be taken between the internal spring bar posts that attach the strap to the case.

There is no universally 'best' strap, only choices grounded in aesthetic vision. Black alligator remains the historical and conservative choice, guaranteeing visual harmony with white gold without competing with quadrant complexity. Vegetable-tanned calf offers evolving patina over time. Shell cordovan provides dense consistency and deep lustre. Technical rubber straps represent the tool-watch choice. Your decision depends on how you intend to use your Complications.

The strap is attached to the case via two spring bars (lugs). To remove it, use a spring bar tool or equivalent: apply light vertical pressure to the bar to release it, then extract gently. Insert the new spring bars into the replacement strap, then reinserert the bar into the case and verify it is firmly locked. If you are inexperienced, consult a watchmaker: the operation is straightforward but the risk of scratching the case is real.

Any strap with a 20mm lug width is technically compatible with the Complications 5205G-013. On milanostraps.it you will find a selection of artisanal straps handcrafted in alligator leather, vegetable-tanned calf, shell cordovan and technical rubber, all with 20mm lugs. Casati Milano additionally offers a bespoke service by appointment at the Milan atelier, where you can select leather and follow production.

Durability depends on material and usage. An alligator or shell cordovan strap, if cared for and dried after humidity exposure, typically lasts 3–5 years of daily wear. Vegetable tanning, being organic, ages more rapidly but produces desirable patina: some enthusiasts consider this evolution part of the strap's beauty. Technical rubber straps offer superior durability (5–7 years) but less aesthetic patina. Casati Milano guarantees 18 months against manufacturing defects; natural wear is expected.
