Strap for Aquis Date 43.5 Bicentenario de Independencia de Guatemala

The Oris Aquis 01 400 7763 4115-Set features a 22mm lug width. This specification is standardised across the model and must correspond to the spring bar holes of your chosen strap. A tolerance of ±0.5mm is generally acceptable, but we recommend precise measurement with a digital calliper for optimal fit. Casati Milano atelier always verifies compatibility prior to customisation.

Selection depends on intended use. For formal contexts: alligator or shell cordovan leather with vegetable tanning. For daily and diving use: FKM rubber or neoprene with steel lugs. For versatility: vegetable-tanned calf with natural patina development, or NATO ballistic canvas. The Aquis accommodates all these solutions whilst maintaining aesthetic coherence, as the case design is fundamentally neutral and functional.

The operation requires a dedicated spring bar tool to remove the elastic pins securing the lugs to the case. Position the tool in the small aperture adjacent to the pin, apply gentle pressure to retract it, then extract the strap. Repeat on the opposite side. For installation, align the new strap with the lug sockets and press the pins until audible engagement. If you prefer to mitigate risk of damage, Casati Milano atelier performs this operation with meticulous precision.

Yes, provided the strap is specifically dimensioned for 22mm lugs. Compatibility depends on the spring bar hole opening: the aperture must accommodate the lug shoulder without excessive clearance (which causes lateral movement) and without binding (which damages leather). We recommend ordering straps explicitly labelled as 22mm and, if uncertain, requesting detailed photographs of the spring bar hole from the supplier.

Longevity depends on tanning method and usage pattern. A vegetable-tanned leather strap, with ordinary care (air-drying after water contact, bi-annual conditioning), typically lasts 4–7 years before replacement becomes necessary. FKM rubber is essentially indestructible unless exposed to sustained high temperatures (>60°C). NATO canvas is indefinitely durable if not subjected to frequent immersion. Alligator leather with vegetable tanning is the most fragile in humid environments (2–4 years), though it is the most aesthetically distinguished option.
