Strap for Artelier Date Diamonds 31 Stainless Steel / Silver / Bracelet

The lug width is 14 millimetres. This dimension, smaller than standard 16 or 18mm offerings, is specific to this model's design and requires precise measurement with a digital calliper before purchasing an aftermarket strap, measuring the internal distance between the attachment pins.

It depends on the context of use. Black or dark brown alligator represents the pinnacle choice for formal occasions, emphasising classical elegance. A vegetable-tanned calf in tobacco colour offers daily versatility with evolving patina over time. For summer use, a cognac-coloured shell cordovan or black rubber strap ensures practicality without aesthetic compromise.

Use a spring bar removal tool to gently depress the attachment pin, sliding the strap out of the spring mechanism. Repeat for the second pin. The operation requires patience to avoid damage to the case. If uncertain, consult the Casati Milano atelier for professional replacement.

Yes. Milano Straps offers a complete collection of 14mm leather straps (alligator, calf, shell cordovan), NATO fabric and rubber, all dimensioned specifically for the 01 561 7687 4031-07 8 14 77 lug width. Each strap is factory-checked for mechanical compatibility and available for rapid shipment.

Durability depends on material and intensity of use. An alligator or shell cordovan maintains structural integrity for 3–5 years with moderate wear. A vegetable-tanned calf, softer in nature, evolves tactilely after 1–2 years but remains functional for up to 4–6 years. Factors such as humidity, solar exposure and frequency of wear accelerate natural ageing.
