Strap for Aquaracer 300M Quartz 27 Stainless Steel / Yellow Gold / MOP - Diamond / Bracelet

The TAG Heuer Aquaracer WAF1425.BA0825 features a 20mm lug width. This measurement represents the space between the two side pins on the watch case and determines the strap width required for proper fit. It is an ISO-standard size, so most quality artisan straps conform to this dimension without variation.

For the WAF1425.BA0825 we recommend alligator straps in bourbon tone to enhance the yellow gold of the two-tone case, or vegetable-tanned calf leather to develop natural patina over time. If you frequently use the watch in water, a high-density NATO or FKM rubber strap offers practicality and durability whilst maintaining the sportiness of the timepiece.

To change the strap on the WAF1425.BA0825, use a spring bar removal tool. Position the thin end of the tool in the lateral slot of the pin, gently push towards the centre of the case to release the internal spring, and the strap will detach. Repeat on the other side. When installing the new strap, ensure the pins are perfectly aligned in the lugs and the strap is not twisted.

Yes, any 20mm aftermarket strap is compatible with the WAF1425.BA0825. However, we recommend choosing specialised brands that guarantee precise tolerances on lug width. Poor quality straps may present ±0.5mm variations that cause unacceptable lateral play on the case.

A quality leather strap (alligator, shell cordovan, premium calf) on a sports watch like the WAF1425.BA0825 typically lasts 2–4 years with daily wear. If frequently exposed to salt water, deterioration accelerates; NATO or rubber straps are more suitable for extended marine environments. Proper maintenance (immediate drying after immersion) extends strap life by 1–2 years.
