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

The lug width of this model is exactly 14 millimetres. This is the distance measured between the two metal pins protruding from the case. To verify correctly, use a digital calliper with the watch unstrapped, measuring orthogonally between the pins. A 14mm strap will have a nominal width slightly less (approximately 13.8–13.9mm) to ensure smooth movement without friction.

For a dress watch of this refinement, we recommend alligator in dark brown (2–3 tones) or Italian vegetable-tanned calf leather. These materials respect the watch's austere design philosophy and develop a natural patina over time. For light daily wear, a NATO in cotton-polyester navy offers versatility and durability. Ideal strap thickness: 1.2–1.4mm in leather, to maintain harmonic proportions with the compact case.

Remove the watch from your wrist. Position the case on a soft cloth with the lugs facing you. Locate the small spring-loaded pin on one side of the lug (usually a small ball or lever). Use a spring bar tool to gently compress the spring, then extract the pin from the case. Repeat on the opposite lug. Insert the new strap's pins into the slots, ensuring the spring clicks into position. If inexperienced, consult a professional watchmaker to prevent case damage.

Yes, absolutely. Any strap with a 14mm lug width is compatible with this model. MilanoStraps offers a curated selection of artisanal straps in leather, NATO, and rubber, all sized for 14mm lugs. Always verify that the new strap's thickness does not exceed 1.8mm to avoid binding at the case shoulders. For straps with a deployante buckle, check that the mechanism does not exert excessive pressure on the case.

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3–5 years of moderate daily wear, with variability based on climate, humidity, and frequency of wear. Leather is sensitive to prolonged humid heat and direct sunlight, which accelerate ageing. A NATO strap, by contrast, lasts 8–10 years due to fabric durability. Maintenance extends lifespan: periodically clean with a damp cloth and store in a dry environment. MilanoStraps provides care instructions specific to each material with every strap.
