Strap for Aquis Date 43.5 Stainless Steel / Green / Calf

The lug width of the Oris Aquis 01 733 7730 4157-07 5 2410EB is exactly 24mm. This width is standard for robust diver watches and allows the use of quality aftermarket straps. To verify the measurement, use a digital calliper to measure the distance between the lugs from the inner shoulder of one to the other.

It depends on use case: for elegant settings, a vegetable-tanned leather strap with visible grain texture respects authentic Swiss heritage and develops patina over time. For genuine marine environments or gym use, a 24mm synthetic yarn NATO strap dries quickly. For zero maintenance, an FKM rubber strap in grey or black offers wet grip and absolute practicality.

Strap change is performed using the spring bars (spring-loaded pins): with a dedicated tool or thin flat screwdriver, gently lever the bar until it disengages from the lug, then remove the old strap. Insert the new strap by aligning the holes to the lug and press until the retention click. We recommend having a magnifying glass on hand to verify correct seating.

Yes, provided the lug width is exactly 24mm. Quality artisanal straps (European leather, premium NATO, industrial rubber) are fully compatible. We recommend straps from specialised suppliers who test attachment on diver cases to guarantee perfect fit and zero play.

A vegetable-tanned leather strap lasts an average of 2-3 years with daily wear in temperate climate. Longevity increases in dry climates and decreases in humid environments or frequent exposure to salt water. Ageing patina is natural and desirable; failure begins when the strap loses elasticity. Occasional beeswax maintenance significantly extends useful life.
