Strap for Aquis Date Calibre 400 41.5 Stainless Steel - Yellow Gold / Blue / Bracelet

The lug width (or strap width) of the Oris Aquis 01 400 7769 6355-07 8 22 09PEB is 22 millimetres. This measurement corresponds to the internal space between the lugs (attachment ears) of the case and determines compatibility with aftermarket straps. You can verify this by measuring directly across the spring bar pins that support the original strap.

For the model 01 400 7769 6355-07 8 22 09PEB, vegetable-tanned leather straps are highly recommended, particularly in alligator or vegetable-tanned calf leather. A navy blue or warm tobacco brown leather strap provides both refined aesthetics and proven durability. Alternatively, NATO fabric straps offer practicality and versatility for daily wear.

The strap is replaced by gently extracting the spring bar pins that pass through the lugs using a specialist tool, watchmaker's instrument, or small flat screwdriver. Pins may be either push-fit type or scalloped (with a small retaining shoulder). We recommend performing this operation on a soft surface to avoid scratching the case, or entrusting the task to a specialist workshop.

Yes, provided it features a 22-millimetre lug width. Artisanal vegetable-tanned leather straps from specialist makers are entirely compatible and often superior in build quality and material selection compared to standard OEM straps. It is essential to verify that the spring bar pin holes match the exact 22mm specification.

A high-quality vegetable-tanned leather strap, with ordinary maintenance (regular cleaning, protection from prolonged UV exposure and excessive moisture), will last between 3 to 5 years of daily wear. Longevity depends on intensity of use, frequency of immersion in fresh or salt water, and the degree of patina development the wearer accepts. Vegetable-tanned leather improves aesthetically over time, developing a characteristic patina.
