Strap for Master Collection 42 Date Stainless Steel / Blue / Alligator XL

The lug width is 21 mm. This measurement represents the distance between the case lugs where the strap attaches. It is essential to respect this exact tolerance: an undersized strap will appear loose, whilst an oversized strap will not fit properly into the case lugs.

For a timepiece of this calibre, French alligator represents the archetypal choice: symmetrical scales emphasise formal character. Vegetable-tanned calf offers intimate patina and controlled ageing. Shell cordovan imparts structural density, whilst NATO and natural rubber are ideal for sporty-quotidian use without compromising craftsmanship.

After removing the original strap (using a small tool to push the spring bars laterally), align the new 21mm strap with the case's lug holes. Insert the first spring bar into the corresponding cavity, then push it through until it reaches the opposite seat. Verify that the strap sits perfectly horizontal and that there is no gap between the case edge and the strap itself.

Yes. Milano Straps offers a curated collection of 21mm straps specifically engineered for this reference. Available in premium materials including alligator, vegetable-tanned calf, shell cordovan and technical textiles, all personalizable in length, initials and thread colour.

Durability depends on material and usage. A superior-grade alligator or calf, with proper maintenance (regular cleaning, protection from prolonged moisture), maintains structural integrity for 4–6 years of daily wear. Shell cordovan is even more resilient. Stitching, executed using Milano Straps' artisanal techniques, is guaranteed for 18 months. Intentional patina (controlled darkening) represents natural leather ageing, not deterioration.
