Strap for Oris Aquis 01 733 7731 4154

The Oris Aquis 01 733 7731 4154 is equipped with 19-millimetre lugs. This dimension results from a proportional calculation that balances the case diameter (37mm) with strap width, preventing optical imbalance. To verify accurately, measure the internal distance between the two shoulders of the spring bar using a digital calliper.

A dark brown alligator strap or Italian vegetable-tanned calf leather accentuates the Aquis's maritime identity. Alligator offers a uniform surface and a finish reminiscent of aquatic dominion; Italian calf, conversely, develops patina over time, transforming daily. Both benefit from stainless-steel hardware without decoration, remaining faithful to the watch's design philosophy.

The lugs on the 01 733 7731 4154 are passive (spring-bar style): slide the new strap beneath the metal spring without removing it. Position the watch on a flat surface, gently push the spring bar laterally to facilitate removal of the old strap, then guide the new one into position. No disassembly is necessary; the operation requires less than one minute. Avoid sharp twists that could damage the spring bar.

Yes, any strap with 19-millimetre lugs is compatible with the 01 733 7731 4154, provided the buckle width does not exceed the case. Artisanal leather, NATO and rubber straps commercially available have been manufactured to industrial standards guaranteeing precise tolerances. Always verify the product specification before purchase.

The lifespan of vegetable-tanned calf leather depends on usage and maintenance. With vegetable tanning, leather is more porous and requires periodic applications of mink oil or balm to maintain elasticity and water resistance. Under normal conditions, a well-maintained strap withstands 3–5 years of daily wear. Excessive humidity and prolonged sun exposure accelerate deterioration; alternating use with NATO or rubber straps significantly extends leather longevity.
