Strap for Aquis Depth Gauge DLC

The lug width is 20mm. This width is specific to the 46mm case of the 01 733 7675 4754-Set RS model and is determined by the geometry of the lugs integrated into the case. To verify compatibility, measure the internal distance between the two passants: it must be exactly 20mm. A narrower strap would be unstable, whilst a wider one would not fit into the lugs without forcing.

The choice depends on intended use. Alligator leather with vegetable tanning is the preferred option for elegance and durability in humid environments: the natural grain tolerates salt oxidation and develops authentic patina over time. Vegetable-tanned calf offers chromatic versatility and sophisticated consistency, requiring regular maintenance. Vulcanised rubber (FKM) remains the pragmatic solution for actual diving and periods of intense humidity, whilst preserving the main leather strap.

Strap replacement is a straightforward procedure. You will need a quality spring bar tool: position the small hook under one of the two lateral pins, apply gentle inward pressure and the pin will retract, allowing you to remove the strap. Repeat on the other pin. When inserting the new strap, align the holes with the lugs and press the pins outward until they click. Precision avoids damage to the new bracelet.

Yes, provided it is the correct lug width (20mm). Milano Straps offers a selection of 20mm straps in various materials: alligator, vegetable-tanned calf, NATO and rubber. All our straps are constructed to the same precision standards as Swiss horology. Before purchase, always verify that the passant is compatible with your Oris Aquis lugs: our straps are engineered to fit without forcing.

The lifespan of a leather strap depends on usage conditions and maintenance. With daily wear in dry environments and regular maintenance (hydrating cream twice weekly), a vegetable-tanned calf strap has a life of 18-24 months. Alligator, thanks to its denser structure, can last 24-36 months. In humid environments or with frequent saltwater contact, lifespan reduces: in such cases, alternating with a rubber strap is advisable to preserve the main leather strap.
