Strap for Aquis Date 43.5 Stainless Steel / Black / Bracelet

The Oris Aquis 01 733 7789 4154-07 8 23 04PEB features a lug width of 23mm. This measurement must be verified internally between the lug terminals using a digital calliper, ensuring that the aftermarket strap seats correctly in the lugs without mechanical play or forced installation.

Selection depends on your intended use. For a luxurious formal profile, an alligator or shell cordovan strap with matte finish amplifies the watch's sobriety. For frequent diving, a vegetable-tanned leather or Cordura NATO strap guarantees water resistance and extended durability. A Fluoroelastomer rubber strap represents the ideal compromise between sport utility and daily wearability.

Changing the strap requires a spring bar tool and careful manipulation. Position the watch face-down on a soft surface. Insert the tool into the small hole beneath the lug, apply gentle pressure to compress the internal spring mechanism, then slide the lug out of the lug post. Repeat on the opposite side. For installation, align the strap's lug ends with the lug post holes, press until the spring bar clicks into place, and verify correct seating.

Yes, any strap manufactured with a 23mm lug width is compatible with the Oris Aquis 01 733 7789 4154-07 8 23 04PEB, provided it meets precision tolerances ensuring secure fit without play. Specialised artisanal brands offer customisable leather, NATO, and rubber straps, guaranteeing longevity and aesthetic coherence with the instrument.

A high-quality vegetable-tanned leather strap typically lasts 2–4 years when subjected to occasional diving with regular maintenance (prompt drying after water exposure). Marine saltwater exposure accelerates ageing. For intensive diving use, alternation with rubber or NATO straps is advisable. The patina developing on leather over time is natural and adds character to the timepiece.
