Frequently asked questions

What is the lug width of the TAG Heuer Aquaracer WBP2151.BA0627?

The TAG Heuer Aquaracer WBP2151.BA0627 has a lug width of 20 millimetres. This width is standard for the 40mm model and is compatible with any artisanal strap manufactured to this specification. To verify the measurement, position a ruler on the lateral lug (the elements that connect the strap to the case) and measure from inside to inside: the result should be exactly 20mm.

Which strap is best for the TAG Heuer Aquaracer WBP2151.BA0627?

The choice depends on usage context. For daily elegance, a blue-grey alligator or a vegetable-tanned calf in tobacco colour enhances the sunburst dial and rose gold. For maximum versatility, a cognac shell cordovan combines durability and natural sheen. If you prefer ease of use, a raw wool NATO allows rapid changes. All these materials respect the visual proportion of the WBP2151.BA0627 and remain true to the watch's technical identity.

How do I change the strap on the TAG Heuer Aquaracer WBP2151.BA0627?

The change requires a specific tool (spring bar tool) or access to a specialised atelier. Identify the lateral spring bars (metal elements visible on the sides of the case where the strap inserts). Use the tool to push the bar outward, being careful not to scratch the case. Once the spring bar is removed, the strap detaches completely. Reverse the process to mount the new strap: align the holes with the lug and push the spring bar until it locks. If you lack confidence, contact a specialised atelier such as Casati Milano, which offers professional service with warranty.

Is the strap I want compatible with the TAG Heuer Aquaracer WBP2151.BA0627?

Yes, if the strap is certified for a 20mm lug width. This width is standard for your model. Always verify with the seller that the strap is compatible with 20mm and that the lug depth (typically 4.8–5.2mm) is appropriate for your watch. Milano Straps' artisanal straps are available in 20mm with adjustable passants that guarantee precise fitting.

How long does a leather strap last on a TAG Heuer Aquaracer WBP2151.BA0627?

Durability depends on intensity of use, climate, and leather quality. An alligator or shell cordovan in vegetable tanning lasts 2–4 years with daily wear under normal conditions. Exposure to salt water (as this is a dive watch) accelerates leather ageing; always rinse the strap with fresh water after sea bathing. Artisanal straps come with an 18-month standard warranty, but with proper maintenance and protective wax reapplied every 6–8 months, useful life extends significantly. The natural patina that forms is not deterioration, but part of the beauty of quality leather.

The next step

The right strap isn't chosen. It is built, together.

From the atelier appointment to delivery, every step is made for those who know that things done well take time. Rare leathers, one piece at a time, eighteen months of warranty.
