Strap for Aquis Date 43 Stainless Steel / Black - Yellow / Rubber

The Oris Aquis 01 733 7653 4127-07 4 26 34EB is fitted with 26mm lug width, the industry standard for cases of this proportion (43mm). This measurement ensures aesthetic stability and compatibility with a wide range of aftermarket artisanal straps. If you intend to replace the original strap, verify that your new strap is specifically dimensioned for 26mm by using a digital calliper to measure the internal distance between the lugs.

The optimal choice depends on your case variant. For blue dials, an alligator or chocolate brown strap creates a noble contrast that emphasises the ceramic bezel. If you prefer artisanal authenticity, vegetable-tanned calf leather in cognac tone pairs perfectly with the case's sporting geometry. For practicality without aesthetic compromise, a grey Cordura NATO strap or FKM rubber deployante maintains the watch's diving heritage. Milano Straps offers curated specialists for every variant.

The strap is secured via standard spring-loaded lugs (spring bars). Using a dedicated tool or thin flat-edged implement, apply pressure to the lower attachment pin to compress the internal spring, then slide the old strap out of the lug. Repeat on the opposite side. Reverse the process to install the new strap, ensuring both spring bars click into position. If you lack the tools, contact Casati Milano: the atelier offers bespoke mounting service by appointment.

Yes, any strap specifically dimensioned for 26mm lug width is fully compatible with reference 01 733 7653 4127-07 4 26 34EB. Oris uses standard spring-bar construction; there are no proprietary features. However, it is essential to verify that your chosen strap is genuinely 26mm (not 24mm or 28mm). Milano Straps guarantees metrological precision on every strap in its collection compatible with this measurement.

Leather strap longevity depends on material quality and daily wear patterns. High-quality calf leather typically lasts 3–5 years with moderate use; alligator, owing to its lower porosity and natural oil resistance, can exceed 7–10 years. Since the Aquis is designed for humid and marine environments, we recommend regularly drying the strap after exposure to salt or fresh water, and occasionally applying luxury-grade leather conditioners. NATO or FKM rubber straps eliminate this maintenance entirely, making them ideal for summer or intensive diving use.
