Strap for Artelier Date Diamonds 31 Stainless Steel / MOP

The lug width is 14 millimetres. This measurement refers to the distance between the two spring bars protruding from the watch case, where the strap ends attach. This is a non-standard dimension in contemporary horology, requiring straps specifically designed for 14mm lug widths.

For a dress watch of this calibre, an alligator strap with vegetable tanning represents the classical choice. Alligator offers subtle natural texture and develops patina over time. Alternatively, vegetable-tanned calf leather is excellent for daily wear, whilst rubber straps are ideal for humid environments or informal sporty occasions.

Use a spring bar removal tool. Position the watch on a soft surface, gently press the spring bar from beneath to release it from the lug hole, then extract the old strap. Insert the new strap by aligning the spring bars into the case lugs and press until you feel the locking click. If uncertain, consult a professional watchmaker.

Yes, aftermarket compatible straps are usable provided they strictly respect the 14mm lug width specification. Always verify that the spring bars are the correct size and that the strap has been constructed with durable materials. Specialised suppliers such as Milano Straps offer bespoke straps for this specific measurement.

Longevity depends upon leather quality and frequency of wear. A vegetable-tanned leather strap, worn occasionally (2-3 times weekly), may last 3-5 years. With daily wear, duration reduces to 18-24 months. Continuous exposure to humidity, heat and perspiration accelerates ageing. Regular maintenance (gentle cleaning and specific conditioner treatments) substantially extends strap lifespan.
