Strap for Aquaracer Professional 200 Solargraph 34 Stainless Steel / Blue

The lug width (ansa width) of the TAG Heuer Aquaracer WBP1311.BA0005 is 20mm. This is the internal distance between the two metal lugs of the case where the strap is affixed. To verify this measurement, use a digital calliper and measure the internal space between the two lugs: the result must be exactly 20mm. Do not confuse this dimension with other case measurements, such as the diameter or dial width.

For the TAG Heuer Aquaracer WBP1311.BA0005, we recommend three primary options. For daily elegant use: vegetable-tanned calf leather in cognac brown or light grey, which develops natural patina over time. For formal occasions: alligator in cognac brown or black, which creates a strong aesthetic contrast with the stainless steel case. For sports or diving activities: NATO textile or FKM rubber strap, which resists moisture and chemical agents. Your choice depends on your predominant usage pattern.

Strap replacement occurs in three phases. First, obtain a spring bar tool, a specialised instrument with a bifurcated end. Position the watch on a soft surface (a microfibre cloth) to avoid scratches. Insert the tip of the spring bar tool into the small hole present under the case lug, pressing gently to release the internal spring of the bar. While maintaining this pressure, extract the metal bar from the old strap. Repeat the operation on the other side. To fit the new strap, reinsert the bars into the corresponding holes, ensuring they lock in position with a perceptible click.

Yes, it is entirely possible and recommended. A 20mm aftermarket strap is completely compatible with the WBP1311.BA0005. Indeed, the use of personalised aftermarket straps allows you to vary the style of your timepiece according to occasion or season. Artisanal straps in alligator, calf, shell cordovan or specialised textile often guarantee superior construction quality compared to the factory bracelet, with manual finishing and total personalisation (monograms, buckle choice, colour variants).

Lifespan depends on the material, tanning method and frequency of use. Quality vegetable-tanned calf, with moderate daily use, reaches 4-7 years before showing signs of structural failure. Authentic alligator lasts 6-10 years under the same conditions. Shell cordovan, the noble horse rump leather, guarantees 15-20 years of regular use without significant deterioration. NATO textile or FKM rubber straps have virtually unlimited material lifespan, although the press-stud buckle may require replacement every 10-15 years. Regular maintenance (gentle cleaning, annual conditioning with specialist creams) considerably extends the operational life of any leather strap.
