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

The Oris Aquis 01 400 7769 4135-07 8 22 09PEB is fitted with 22mm lugs. This dimension, measured between the two case attachments, uniquely determines the compatibility of any aftermarket strap. Always verify the lug width before purchase to ensure proper fitment.

For the 41.5mm Oris Aquis, we recommend Italian leather from vegetable tanning in moka or cognac tones if you prefer aesthetic maturity and patina development. For intensive marine use, FKM rubber or ballistic canvas NATO ensure superior resistance to chlorine and saltwater. The ideal strap depends on your priority: elegance with maintenance or absolute practicality.

Strap changing requires a spring bar removal tool to extract the pins securing the strap to the case lugs. Position the watch on a soft surface, gently push the pin from the opposite side until it emerges, then slide off the old strap. Insert the new strap and reinsert the pin, ensuring it is secured symmetrically on both sides.

Yes, any strap with 22mm lugs is compatible with the Oris Aquis 01 400 7769 4135-07 8 22 09PEB. Milano Straps crafted straps are manufactured in Italian leather, alligator, shell cordovan, technical rubber and NATO, all available in 22mm width. Always confirm the lug width matches before purchase.

A quality handcrafted leather strap on a moderately weighted watch like the 41.5mm Oris Aquis lasts approximately 3-5 years with daily wear. Longevity depends on maintenance (protection from excessive moisture, drying after perspiration), tanning quality (vegetable tanning resists chrome tanning) and frequency of wear. Leather develops natural patina and becomes more supple over time without losing structural integrity if properly preserved.
