Frequently asked questions

What is the lug width of the TAG Heuer Aquaracer WBP231M.BA0618?

The lug width of the TAG Heuer Aquaracer WBP231M.BA0618 is 20 mm. This dimension corresponds to the internal spacing between the two lugs on the case and represents the maximum width of a compatible strap. It is essential to measure accurately before purchase using a calliper positioned perpendicular to the dial.

Which strap is recommended for the TAG Heuer Aquaracer WBP231M.BA0618?

For the WBP231M.BA0618, straps in alligator are recommended for formal contexts, vegetable-tanned calf for elegant versatility with evolving patina, nylon NATO in UV-resistant yarn for sports applications, and ventilated rubber for aquatic environments. Choice depends on intended use and personal aesthetic preferences. Milano Straps offers both ready-made straps in these variants and custom realisation at the Casati Milano atelier.

How do I change the strap on my TAG Heuer Aquaracer WBP231M.BA0618?

The strap is replaced by extracting the lug pins using a spring bar tool. Insert the bifurcated tip of the tool into the slot beneath the lug, apply gentle pressure to relax the internal spring and slide the pin out of the case. Repeat on the opposite lug. Insert the new strap by aligning the holes and reinsert the pins until they click into place. If inexperienced, Milano Straps staff can assist free of charge for purchases made through our website.

Are aftermarket straps compatible with the TAG Heuer Aquaracer WBP231M.BA0618?

Yes, any strap with a 20 mm lug width is compatible with the WBP231M.BA0618. High-quality artisanal aftermarket straps, such as those crafted by Milano Straps, guarantee precise finishing and selected materials that often exceed OEM straps in elasticity and aesthetic appeal. Compatibility is assured by adherence to the standard 20 mm lug width specification.

How long does a leather strap last on the TAG Heuer Aquaracer WBP231M.BA0618?

A high-quality artisanal alligator or calf leather strap lasts between 5 and 10 years in daily wear, varying according to frequency of use and maintenance. Vegetable-tanned leather permits greater longevity (up to 15 years), developing a patina that attests to its authenticity. Straps realised by Milano Straps include 18-month warranty and can be regenerated on request, with re-stitching of lugs and replacement of worn passants.
