Strap for Artelier Date 40 Stainless Steel / Black / Bracelet

This model features a lug width of precisely 21mm. This dimension is integrated into the case and tolerates no variance: the strap must seat perfectly between the lugs to ensure correct suspension and everyday ergonomic handling. Always measure with a digital calliper from the inside of the case to verify compatibility of an aftermarket strap.

The optimal choice depends on usage and desired aesthetic coherence. For daily elegance, we recommend alligator with vegetable tanning in dark brown tone, which dialogues with the case's satin finish while maintaining the instrument's functional vocation. For robustness, a linen-cotton NATO repositions the watch as a true tool. Shell cordovan horsehide offers dramatic patina development over time, whilst FKM rubber in satin finish guarantees absolute water resistance without maintenance.

Strap replacement requires a spring bar removal tool. Insert the flat tip of the tool into the hole beneath the lug, applying gentle downward pressure to release the spring-loaded pin. Repeat on the opposite side. Remove the worn strap and insert the new one, ensuring the pins lock firmly into the case's lug seats. Verify the strap is centred and does not protrude beyond the case sides before wearing.

Yes, provided the lug width is exactly 21mm. Aftermarket straps of artisanal quality, such as those crafted by Casati Milano, respect precise tolerances and offer accurate spring bar seats. Always verify that the bar seats adhere flawlessly to the case lugs with no lateral play. Avoid generic mass-produced straps: construction quality directly influences daily usability and the watch's overall longevity.

Longevity depends on tanning method and material. Vegetable-tanned alligator resists 4-6 years of daily wear, with patina improving through natural ageing. Textured calf, softer in hand, offers similar durability but requires periodic maintenance (natural wax application every 6-12 months). Shell cordovan horsehide lasts 6-8 years with regular wear, developing spectacular amber patina. FKM rubber has no structural wear limit, though surface satin finish may dull after 3-4 years of intense sun exposure.
