Strap for Aquaracer Professional 300 42 Stainless Steel / Blue

The lug width of the TAG Heuer Aquaracer WBP5111.BA0013 is 20mm, measured centre-to-centre between the lugs. This dimension is fixed by the 42mm case geometry and must be respected precisely to ensure proper fit and stability on the wrist.

Three options are recommended: alligator in black with white stitching (maximum refinement), vegetable-tanned calf leather in dark brown (sporting elegance with natural patina development), or FKM rubber for intensive water use. The choice depends on your desired balance between elegance and functionality.

Use a spring bar tool to remove the pins from the lugs. Position the tool in the small lateral slot, apply gentle upward pressure and extract the pin. Align the new strap's holes with the lugs and reinsert the pins until they click into place. Avoid excessive force to prevent case damage.

Yes, any strap with a 20mm lug width is mechanically compatible. We recommend straps with a deployante clasp for this 42mm case, as they provide superior security and weight distribution. Artisanal straps in premium vegetable-tanned leather improve daily usability and age nobly.

Durability depends on material and use: premium vegetable-tanned leather resists 3–5 years of daily wear, developing characteristic patina. Avoid prolonged saltwater exposure without subsequent drying. For intensive humid environments, prefer FKM rubber straps. Proper maintenance—drying after immersion, occasional feeding with specialised cream—significantly extends longevity.
