Strap for Aquaracer 300M Calibre 9 Automatic 32 Stainless Steel / Black MOP / Bracelet

The lug width (ansa width) of the TAG Heuer Aquaracer WBD2310.BA0740 is 16mm. This measurement represents the internal distance between the two spring bar attachment holes. It is essential to verify this dimension before purchasing an aftermarket strap, as an incompatible lug width will not fit correctly on the case.

For this sport-elegant model, we recommend three primary options: dark alligator (black or navy blue) for formal harmony with the stainless steel; vegetable-tanned calf leather for aesthetic development over time; black technical rubber for frequent water wear. Each choice should reflect your predominant wearing style and intended context.

Obtain a spring bar remover tool (small specialised screwdriver with bifurcated tips). Position the watch with the lug facing upward, gently insert the bifurcated tip into the micro-hole beneath the spring, push downward until the pin compresses, then remove the old strap. Repeat on the opposite side. Insert the new strap by aligning the holes and press until you hear the spring lock click.

Any strap with a 16mm lug width is compatible. On milanostraps.it you will find a complete collection of 16mm straps in premium leather (alligator, calf, shell cordovan), technical rubber, and NATO fabric. All are manufactured to horological standards and can be fitted directly without modification.

A quality leather strap worn daily has an average lifespan of 3–5 years. Determining factors include: frequency of wear, exposure to moisture/sunlight, periodic care (water-repellent treatments), and tanning quality. A shell cordovan strap lasts longer due to fibre density. With Casati Milano atelier, you receive an 18-month warranty and the option of early strap replacement if wear occurs.
