Strap for Aquis Date 36.5mm Stainless Steel / Black / Rubber

The Oris Aquis 01 733 7731 4154-07 4 18 64FC features a lug width of exactly 18 millimetres. This measurement is proportioned to the 36.5 mm case diameter, ensuring visual balance and wearing comfort. Verifying the measurement is straightforward: position a ruler perpendicularly across the case between the two attachment points and measure the distance. Any strap with 18 mm lug width will fit perfectly on this model.

The ideal strap depends on intended use and personal preference. For formal elegance, an Australian alligator with vegetable tanning offers maximum luxury. For everyday versatility, vegetable-tanned calf leather develops organic patina over time. For genuine underwater use, an FKM rubber strap remains the uncompromised choice. A ballistic nylon NATO offers the most casual and reconfigurable solution. Casati Milano recommends trying directly at the atelier to make a conscious choice.

Strap replacement is a delicate operation requiring attention. Obtain the correct tools: a spring bar tool and a protected surface for the case. Position the watch securely, insert the spring bar tool into the lateral holes beneath the lug, and gently compress the internal spring to release the spring bar. Once the strap is removed, insert the new one by perfectly aligning the spring bars into the corresponding holes. If inexperienced, entrust the operation to a professional.

Yes, absolutely. Any strap with an 18 mm lug width is compatible with the Oris Aquis 01 733 7731 4154-07 4 18 64FC. Milano Straps offers an extensive range of artisanal straps in leather, NATO, and rubber, specifically selected and tested for reliability. Italian artisanal quality guarantees superior finishing, stitching, and materials compared to industrial alternatives. Frequent strap changes extend the life of the original bracelet and allow adapting the watch to different contexts.

Leather strap durability depends on intensity of use, tanning type, and environmental conditions. A vegetable-tanned calf strap, worn daily, develops visible patina within 6-12 months and maintains functionality for 3-5 years of moderate use. Superior-quality alligator can exceed 5-7 years if properly maintained. Humidity, perspiration, and sun exposure accelerate ageing. Periodically applying strap-specific balm considerably extends leather life. An FKM rubber strap offers greater longevity, typically 5-10 years depending on UV exposure.
