Strap for Aquis GMT 43.5 Stainless Steel / Blue / Rubber

The Oris Aquis 01 798 7754 4135-07 4 24 65EB features a 24-millimetre lug width, measured between the inner pins of the case. This width is specific to this 43.50mm case architecture and is proportioned to maintain the visual balance of the model on the wrist.

Strap selection depends on intended use. For everyday elegance, we recommend genuine alligator leather with vegetable tanning in tobacco or dark brown tones. For frequent diving, fluoroelastomeric rubber offers superior practicality and longevity. A military-grade NATO strap represents the ideal compromise between versatility and robustness.

Strap replacement requires a dedicated spring bar removal tool, available in standard maintenance kits. Insert the tool at the lug pins, apply calibrated pressure until detachment occurs, then insert the new 24mm strap into the same housings until a secure click is heard. If uncertain, consult a specialist watchmaker.

All straps with 24mm lug width are compatible, regardless of brand or material. Milano Straps offers a dedicated collection of 24mm straps in leather, NATO, and rubber, specifically curated for the proportions and aesthetics of Swiss sports models such as the Aquis.

A quality artisanal leather strap lasts approximately 3–5 years with daily use, provided regular maintenance: air-drying after prolonged water contact, periodic cleaning, and conditioning with hydrating creams every 6–12 months. Vegetable-tanned leather improves over time, developing a natural patina. Frequent immersion significantly reduces this lifespan.
