Strap for Oris Aquis 01 733 7770 4158

The Oris Aquis 01 733 7770 4158 has a lug width of 19 millimetres. This dimension is specific to the 37mm case and results from careful proportional balance between case diameter and lug thickness. Always verify the measurement with a digital calliper, positioning the tool between the strap attachment pins.

The choice depends on intended use. For daily elegance, we recommend vegetable-tanned leather (Tuscan, cognac or dark brown). For nautical practicality and frequent diving, a bidensity NATO fabric or FKM rubber are the most logical options. For pure luxury, shell cordovan offers natural texture and lightness, though it requires protection from salt water.

Remove the old strap by pushing the spring pins inward with a flat tool. Align the new strap holes with the pins and push until you hear a slight click. Verify stability by gently tugging. If unsure, consult a watchmaker to avoid damage to the lugs.

A high-quality leather strap (minimum 1.4mm thickness) typically lasts 3–5 years with daily use. Longevity is influenced by sun exposure, humidity, perspiration and diving frequency. Vegetable-tanned straps age by developing patina, whilst chrome-tanned versions are more durable but less characterful. For a diver used frequently in water, we recommend rotating with NATO or rubber to extend leather lifespan.
