Strap for Oris Aquis 01 400 7769 6355

The lug width of the Oris Aquis 01 400 7769 6355 is 22 mm. This measurement is standard for the 43.5 mm case and allows immediate fitting of all compatible straps in our 22 mm collection. To verify, use a calliper to measure between the lateral spring bar posts—it should read exactly 22 mm.

The choice depends on use case: for diving and wet environments, a NATO canvas strap or rubber strap with a solid deployante clasp is ideal; for daily wear, Italian vegetable-tanned calf leather in brown or grey offers elegance and durability; for saltwater exposure, leather is not recommended. The Aquis's 22 mm lug width accommodates all these options without any proportional issues.

Use a spring bar removal tool or fine needle. Insert the tool into the lateral hole of the case, push the spring bar inward to free one end, then slide out the strap. To install the new strap, insert the guide pin into the lug hole, then press home firmly with the tool until the bar clicks into place. Ensure the pin is fully seated before wearing the watch.

Yes, provided the strap is certified for 22 mm lug width. All our straps are guaranteed for this measurement and will fit any Aquis model without adaptation. We recommend quality-certified straps to prevent premature wear on the spring bar attachment points.

A quality vegetable-tanned leather strap typically lasts 3–5 years with daily use and regular maintenance. Longevity depends on environmental factors (humidity, direct sunlight, chemical exposure) and care habits: clean regularly with a damp cloth and air-dry to significantly extend life. NATO and rubber straps offer greater durability (5–7+ years) under normal conditions.
