Strap for Aquis Date Diamonds 36.5 Stainless Steel / Blue - Diamond / Textile

The lug width of this model is 18 mm, measured as the internal distance between the two spring bar holes at the case extremities. Precise measurement is essential to avoid straps that are either too loose or too tight.

The ideal strap depends on usage and aesthetic preference. For formal-sport styling, vegetable-tanned alligator develops character through patina over time. For versatility, a high-density polyamide NATO offers quick changes and moisture resistance. FKM rubber excels in prolonged aquatic environments, whilst shell cordovan provides sophisticated lustre with greater delicacy.

The spring bars are fixed (non-removable). A spring bar tool is required to extract them without damaging the lugs. Position the tool in the lateral holes, apply slight pressure, and the bar will release. Align the new strap's holes with the lug channels, then push the spring bar until you feel the retention click. Without proper tools, consult a qualified watchmaker.

Yes, any strap with 18 mm lug width is compatible. Milano Straps offers an artisanal collection of leather, NATO, and rubber straps precisely dimensioned for this specification. Always verify that the strap is declared 18 mm and that spring bars are standard gauge before purchase.

Lifespan depends on tanning method, usage frequency, and environmental conditions. Quality vegetable-tanned leather (alligator, naturally tanned calf) lasts 3–5 years with moderate wear, developing desirable patina. Prolonged water or intense perspiration exposure reduces longevity to 18–24 months. Shell cordovan is more resilient (5–7 years), whilst regenerated leather is less durable (12–18 months). Periodic maintenance extends service life significantly.
