Strap for Master Collection 44 Chronograph Stainless Steel / Silver-Arabic / Bracelet

The lug width is 22mm. This measurement is essential when purchasing a compatible strap. To verify it, measure the horizontal distance between the two holes (or slots) where the strap attaches to the case. The Longines Master Collection L2.859.4.78.6 features this standard 22mm dimension, typical of mid-to-high calibre automatic sports watches.

Cognac brown alligator is the most elegant choice, as its regular grain texture creates a refined contrast with the brushed stainless steel case. Vegetable-tanned calf leather offers versatility and a patina that develops beautifully over time. Shell cordovan provides exceptional density and durability, whilst NATO strap in high-tenacity polyamide is the practical, water-resistant option for daily wear.

The strap is changed using a spring bar removal tool. Gently remove the spring bar on one side of the case, slide out the old strap, and insert the new one, aligning it with the lug holes. The operation takes approximately 2 minutes. For visual guidance, contact our Casati Milano atelier for a consultation.

Yes, any strap with a 22mm lug width is compatible. We recommend ensuring that the strap lugs are sufficiently robust for the brushed stainless steel case, and that thickness does not exceed 3.5-4mm to avoid excess bulk. The Italian artisanal straps from milanostraps.it are crafted to ensure optimal proportions on this model.

A high-quality leather strap, with proper maintenance, typically lasts 2-4 years of regular wear. Durability depends on leather quality (alligator, calf, shell cordovan), exposure to moisture, and weekly wear hours. Avoid stagnant water and periodically apply leather-specific conditioner. Casati Milano atelier offers an 18-month warranty on all bespoke straps.
