Strap for Grand Arkade Big Date Platinum / Silver

The Arkade 106.025 is equipped with an 18-millimetre lug width. This measurement refers to the distance between the two protruding lugs on the case (where the strap ends are inserted). To verify compatibility, measure this space with a calliper: it must be exactly 18 millimetres. milanostraps.it offers a complete collection of straps in this size.

Given the refined construction and platinum case material, we primarily recommend black or chocolate-brown alligator for maximum formality, or burgundy-dark shell cordovan if you desire natural patina development over time. Vegetable-tanned calf leather represents a contemporary alternative that softens progressively with wear. By appointment, the Casati Milano atelier can guide you through personalised leather selection.

The procedure requires specialist tools: a spring bar tool for lug pin extraction, or ideally the hands of a skilled watchmaker. Proceed as follows: remove the worn strap by loosening the first pin (small metal cylinder running through the lug), slide it outward, then extract the strap from its seat. Insert the new strap by aligning the holes at the ends, reinsert the pin ensuring it clicks into position. If uncertain, entrust the work to a professional: platinum does not forgive maintenance errors.

Yes, provided it is of equivalent quality and respects the 18-millimetre lug width. A low-quality aftermarket strap compromises both aesthetics and case integrity, potentially scratching the platinum or causing alignment issues. milanostraps.it offers artisanal straps manufactured to the same precision standards as luxury manufactures: alligator, shell cordovan, vegetable-tanned calf, certified for complete compatibility.

Longevity depends on material and usage. High-quality alligator with careful vegetable tanning lasts 4–6 years with daily wear. Shell cordovan, being denser, can extend to 6–8 years. Vegetable-tanned calf softens progressively and typically develops (in a positively aesthetic sense) after 3–5 years of intense use. In formal, occasional contexts, lifespan extends further. Casati Milano guarantees 18 months against manufacturing defects; natural leather wear is not covered, but represents the characteristic and desirable evolution of the strap.
