Strap for Excellence La Semaine Louis Erard x Alain Silberstein III Titanium / Khaki

The lug width measures 23 millimetres, determined by the attachment geometry to the titanium case. This non-standard dimension requires dedicated straps and is incompatible with generic 22 or 24 millimetre variants. Measuring the interior of the lug with a digital calliper ensures correct selection.

Alligator in cognac or brown tones is the classical formal choice, creating significant aesthetic contrast with raw titanium. For daily wear, vegetable-tanned calf develops organic patina; nylon NATO straps guarantee resistance and versatility; elastomeric rubber offers practicality without chemical alteration of the titanium case over time.

Using a spring bar tool, apply controlled pressure to the lateral elastic pins of the lug, releasing the old strap. Insert the new strap by aligning the lug to the lug hole and push the spring until the locking click engages. This operation requires precision to avoid damaging the titanium attachment; Casati Milano provides technical assistance by appointment.

Yes, provided they are specifically dimensioned to 23 millimetres lug width. Quality aftermarket straps, crafted in alligator, calf, NATO or rubber, ensure mechanical compatibility without compromise. Milano Straps offers a broad selection of artisanal alternatives ready for shipment or customisable.

An alligator or calf strap, rotated monthly across other models, maintains structural integrity for 4–6 years. Durability decreases if worn daily in humid or saline environments, where titanium does not transfer moisture but leather deteriorates. Vegetable tanning ages more gracefully than chrome tanning, developing visible patina; periodic conditioning with mink oil significantly extends useful life.
