Strap for Aquaracer Professional 300 36 Stainless Steel / Pink - Diamond / Bracelet

The lug width (ansa width) of the TAG Heuer Aquaracer WBP231J.BA0618 is 20 millimetres. This measurement is the essential parameter for selecting a compatible strap. It is measured by positioning a calliper on the inner shoulder of the case lug without compressing the material.

For the WBP231J.BA0618, several materials are recommended depending on intended use. Alligator represents the most elegant choice, with a natural grain that contrasts with the ceramic bezel. Vegetable-tanned calf leather offers compact texture and a patina that evolves over time. For intensive water activities, an FKM rubber or polyamide NATO strap guarantees superior moisture resistance.

The WBP231J.BA0618 features integrated, non-removable lugs. Changing the strap requires a specific tool (spring bar tool) to lift the springs that hold the strap to the lugs. The operation should be performed with care to avoid damaging the articulation points. A certified watchmaker can complete the change in just a few minutes without risk.

Milano Straps offers bespoke artisanal straps specifically designed for this model, crafted in premium materials such as alligator, shell cordovan, and vegetable-tanned leather. The artisanal quality guarantees superior aesthetic harmony compared to mass-market accessories and extended durability.

The lifespan of a leather strap depends on frequency of use, material type, and maintenance. An alligator or shell cordovan strap, if properly cared for (protection from excess water and regular cleaning), can maintain structural integrity for 5–7 years of daily wear. Vegetable-tanned leather tends to develop a patina that improves over time. Milano Straps offers an 18-month warranty on its bespoke straps.
