Strap for Aquaracer 300M Quartz 35 Stainless Steel / Diamond / Black / Bracelet

The lug width of the TAG Heuer Aquaracer WAY131G.BA0913 is 20mm. This is the space between the lugs where the strap attaches to the case, and it represents the standard dimension for fitting compatible aftermarket straps. Accurate measurement is essential before purchasing a replacement strap.

For the Aquaracer WAY131G.BA0913, we recommend polished alligator leather for its superior water and salt resistance, or vegetable-tanned calf if you prefer natural patina development over time. Vulcanised rubber is ideal for intensive use in wet environments. Avoid shell cordovan, as it cannot tolerate prolonged marine exposure.

To change the strap, you must remove the spring bars that connect the strap to the case lugs. Use a dedicated spring bar tool or contact a professional watchmaker. The WAY131G.BA0913 has 20mm lugs, so the new strap must match this width precisely. Avoid forcing the spring bars, as this may damage the case.

Yes, the WAY131G.BA0913 is compatible with any high-quality 20mm strap. Artisan aftermarket straps often offer superior build quality and customisation options compared to the factory bracelet. Ensure the strap features a robust spring bar system and that the buckle is proportionate to the case dimensions.

A quality leather strap, with proper care, lasts 3-5 years under normal conditions. With regular exposure to moisture and salt water, durability decreases to 18-24 months. Vegetable tanning, whilst developing attractive patina, is more sensitive to prolonged humidity. A rubber or alligator strap lasts significantly longer—5-7 years—especially if treated with protective products.
