Strap for Aquis Date 43 Stainless Steel / Blue / Rubber

The lug width of this model is 22 millimetres. This is the distance between the spring bar pins on the case: this dimension is critical for proper strap installation and must be respected precisely to avoid play or anomalous stress on the bars.

The choice depends on intended use. Alligator leather provides discreet elegance without compromising quality. Vegetable-tanned calf ages nobly and develops patina over time. Cotton hydrophobic NATO is perfect for marine environments and frequent water exposure. FKM rubber is the pure technician's choice, appropriate for diving and continuous wear without aesthetic compromise.

You need to use a spring bar tool to compress the suspension pins. Position the tool on the bar, compress the pin gently from the opposite side, then remove the bar by pushing it outward from the case. Repeat on the other side. Insert the new strap by positioning the pins in the seats and slowly release the spring bar tool for final tightening.

Yes, any strap with a certified 22 millimetre lug width is compatible with the Aquis. However, it is advisable to verify that the strap has appropriate thickness and rigidity to avoid creating play or stress on the case. Milano Straps artisanal straps are specifically calibrated for this geometry.

A quality leather strap, worn daily, has an average lifespan of 3-5 years before the fibre begins to visibly fail. This varies depending on the tanning used: vegetable-tanned calf tends to develop more resistant patina than chrome-tanned leather. Exposure to sweat, moisture and sunlight accelerates fibre ageing. Proper maintenance (drying and occasional conditioning with specific creams) significantly extends lifespan.
