Strap for Aquaracer Professional 300 36 Stainless Steel / Black / Bracelet

The lug width of the TAG Heuer Aquaracer WBP231D.BA0626 is 20 millimetres. This dimension represents the free space between the two lugs of the case (the horizontal pins in ceramic and steel) and is the critical value for ensuring compatibility with any replacement or bespoke strap. Always measure this width by observing directly the lateral lugs of the case before ordering a new strap.

For the WBP231D.BA0626, several solutions are recommended depending on use. Alligator is the choice of maximum aesthetic contrast, with a regular grain pattern that enhances the hybrid case in ceramic and steel. Vegetable-tanned calfskin offers instead chromatic dynamism and a patina that evolves over time. Shell cordovan represents the premium solution, with a translucent profile and density that creates a unique visual dialogue with the case. A NATO strap in double-pore canvas remains ideal for summer versatility. For underwater use, naturally vulcanised rubber is the most functional choice for diving.

The strap on the TAG Heuer Aquaracer WBP231D.BA0626 is replaced by removing the lateral pins (bars) that secure the strap to the case lugs. Use a dedicated tool (spring bar tool) to gently lift the internal catch of the pin, then extract the pin from its seat. Repeat the operation on the other lug. To mount the new strap, insert the pin into the seat of the new strap, then guide the bar into the case lug housings until a click is heard. If you are not experienced, contact us for professional replacement: it requires no significant additional costs and guarantees absence of damage.

Yes, any strap with a 20-millimetre lug width is compatible with the TAG Heuer Aquaracer WBP231D.BA0626. Milanostraps offers a complete range of 20mm straps ready for dispatch, customisable in leather (alligator, calfskin, shell cordovan), fabric (NATO) and technical rubber. Compatibility is guaranteed by the sole condition that the lug width of the strap exactly matches the 20 millimetres specified for this model. All our straps are subject to fitment inspection before dispatch.

The lifespan of a leather strap depends on the material and use. A quality vegetable-tanned calfskin, worn daily, maintains full functionality for 3–5 years before requiring aesthetic replacement (not structural). Shell cordovan, due to its greater density, can reach 8–10 years. Alligator occupies an intermediate position, with 5–7 years of typical life. These timeframes are significantly reduced if the strap is exposed to moisture, direct heat or salty environments (diving). A naturally vulcanised rubber strap, by contrast, resists 5–8 years even with frequent underwater use. Regular maintenance (dry cloth cleaning, annual conditioning) significantly extends the life of any leather material.
