Strap for Aquis Small Seconds Date 45.5 Stainless Steel / Blue / Bracelet

The Oris Aquis 01 743 7733 4135-07 8 24 05PEB features a lug width of 24mm. This dimension is specific to the model and represents the distance between the outer attachment pins measured vertically at the 12-6 position. To verify, position a calliper perpendicular to the centre of each lug and record the resulting value, which must be 24mm to ensure compatibility with aftermarket straps.

For intensive underwater activities, we recommend a 24mm FKM (Viton) rubber strap in black or navy blue. Rubber offers superior grip, rapid drying, and prolonged resistance to saline environments. Alternatively, a cotton-nylon NATO strap provides sports functionality whilst maintaining versatility. For occasional recreational diving, a vegetable-tanned alligator strap maintains elegance with good moisture resistance.

Use a spring bar removal tool to access the elastic pins beneath the case. Position the watch on a stable surface with the dial facing downward. Insert the tool into the space between the lug and strap, gently pushing towards the centre to compress the pin. Repeat on the opposite side. Remove the worn strap. Insert the 24mm pins of the new strap into the attachment holes and press until locked. Verify that the strap is securely fastened before wearing the watch.

All straps with a 24mm lug width are compatible with the Oris Aquis 01 743 7733 4135-07 8 24 05PEB, provided the spring bars are standard gauge. Options include: vegetable-tanned alligator, fine-grained calf leather, shell cordovan, cotton-nylon NATO, FKM rubber, and technical fabrics. Milano Straps offers a curated selection of 24mm straps in various finishes, tested for compatibility and durability. Avoid approximate tolerances: a 23.8mm lug risks slipping, whilst 24.2mm may stress the pins.

A high-quality natural leather strap (alligator, calf, shell cordovan) lasts approximately 3–5 years in daily use on a professional 45.5mm watch. Durability depends on: usage frequency, moisture exposure (diving shortens lifespan), tanning quality, and maintenance. Vegetable-tanned leather ages magnificently, developing deep patina and characteristic texture. If exposed to frequent saltwater, anticipate replacement within 2–3 years. An FKM rubber strap maintains its original appearance for 4–6 years with minimal maintenance.
