Strap for Aquis Date 41.5 Stainless Steel / Blue / Bracelet

The lug width is 22 millimetres. This standard ensures balanced proportions relative to the 41.50-millimetre case diameter and permits fitting any artisanal strap constructed to this specification, from leather to steel to NATO.

It depends on intended use. For formal elegance we recommend alligator or vegetable-tanned calf: both age nobly. For tactical versatility, regenerated-fibre NATO offers rapid changeover and durability. For authentic aquatic use, vulcanised rubber is hyper-hygienic and resistant to chronic moisture.

The strap attaches to the lugs via spring bars or a deployante mechanism. If your model uses traditional spring bars, employ a spring bar tool to remove the metal pins. Insert the new lug shoulders beneath the lugs, ensuring they click into position. For a deployante, release the mechanism on the side, replace the strap, and close.

Yes, provided the lug width is 22 millimetres. All artisanal straps constructed to this dimension fit perfectly. We recommend verifying whether your watch uses standard spring bars or a deployante mechanism, as this affects replacement convenience.

Vegetable-tanned leather resists structural degradation for 2–4 years of daily wear, provided it is rarely exposed to prolonged immersion. Saltwater accelerates ageing. If you wear the Aquis frequently in water or chronic humid environments, prefer rubber or NATO. Leather develops authentic patina in fold zones: this is character, not defect.
