Strap for Aquis Date 43.5 Titanium / Grey / Rubber

The lug width (ansa width) is 24mm. This parameter represents the distance between the horizontal attachment pins of the case, measured from inner wall to inner wall. It is the fundamental value for selecting compatible straps: any strap with an attachment thickness designed for 24mm will insert perfectly into the lateral case lugs.

The choice depends on primary usage. For professional diving, a technical rubber strap (FKM or medical silicone) guarantees total water-resistance and reliable grip. For elegant daily wear, an alligator or vegetable-tanned calf creates sophisticated contrast with the titanium-ceramic case. A heavy cotton NATO is the versatile solution for those alternating formal settings and marine adventures.

Changing the strap on this case is a quick operation: locate the two lateral attachment pins (one on each side), use a spring bar tool or dedicated instrument to gently compress the internal spring of the pin, extract the pin itself and remove the worn strap. Insert the new strap by aligning the passage holes to the pins, then reinsert the pins until you hear the locking click. Verify that the strap does not rotate around the pins before wearing the watch.

Absolutely. Provided the strap is constructed for a 24mm lug width and the thickness dimensions are compatible with the case lugs—a parameter most artisanal manufacturers specify during design—a well-crafted aftermarket strap can deliver superior aesthetic and functional results compared to standard straps supplied with the watch.

Durability depends on tanning and care: quality vegetable-tanned leather, in non-chronically humid environments, lasts 3–5 years before replacement becomes necessary. A strap regularly exposed to saltwater deteriorates faster (12–24 months), as salt compromises fibre structure and leather integrity. For frequent diving, technical rubber represents the most rational investment: it lasts decades without structural compromise.
