Strap for Master Collection 40 Date Stainless Steel / Blue / Bracelet

The lug width of the L2.793.4.92.6 model is 21 mm. This measurement is essential for purchasing compatible straps: it must be measured precisely on the internal lug bar between the two fixing pins. A 1 mm error would result in instability or mounting impossibility.

Natural alligator represents the stylistically most appropriate choice for the Master Collection: its geometric grain harmonises with the chronograph's sober elegance. For durable wear, vegetable-tanned calf offers a patina that improves with time. For sporty contexts, a cotton-nylon NATO allows you to fully exploit the 300-metre water resistance without concerns about strap damage.

Obtain a spring bar tool with tips of appropriate diameter for the fixing pin (approximately 1.4–1.6 mm). Position the watch on a cushion, press the pin from the opposite side with the spring bar tool to extract it completely. Remove the old strap, insert the new one by aligning the hole to the lug bar, then reinsert the pin by pushing until it locks.

Yes, all straps with certified 21 mm lug width are compatible. However, only artisanal straps manufactured with precise construction tolerances guarantee optimal fit without lateral movement. Avoid cheap generic straps: manufacturing quality impacts both longevity and mounting security.

A high-quality calf strap with vegetable tanning lasts 4–6 years with regular daily wear. A naturally treated alligator reaches 7–8 years with care. Duration depends on climate humidity, frequency of wear, and periodic maintenance (gentle cleaning, conditioning every 12–18 months). Casati Milano's 18-month warranty covers manufacturing defects and initial settling.
