Frequently asked questions

What is the lug width of the TAG Heuer Aquaracer WAY131M.BA0748?

The TAG Heuer Aquaracer WAY131M.BA0748 features a 20mm lug width. This measurement is taken between the inner edges of the case lugs and is critical for selecting compatible straps. Always verify with a calliper to ensure correct ordering.

Which strap is recommended for the WAY131M.BA0748?

For the WAY131M.BA0748, we recommend black or navy blue alligator for formal settings, brown calf leather with visible grain for a textured aesthetic, or dark grey rubber for sports and aquatic use. Your choice depends on lifestyle and how much you wish to enhance the mother-of-pearl dial's luminosity. Ideal thickness remains between 1.2 and 1.5mm to respect the proportions of the 35mm case.

How do I change the strap on this TAG Heuer model?

The WAY131M.BA0748 uses a traditional spring bar system. Equip yourself with a spring bar tool (extractor) or consult a watchmaker. Position the flat end of the tool into the grooved spring bar and gently push upward: the lugs will retract, allowing you to remove the old strap and insert the new one. Work carefully to avoid scratching the case.

Can I use aftermarket straps compatible with the TAG Heuer WAY131M.BA0748?

Yes, provided they feature the correct lug width (20mm) and appropriate thickness (1.2-1.5mm). Milano Straps offers artisanal straps certified compatible with your Aquaracer, crafted from premium leather or rubber. Always verify that your spring bar tool is compatible with your case's lugs.

How long does a leather strap last on a watch like the WAY131M.BA0748?

A high-quality leather strap (alligator, calf, shell cordovan) with moderate wear lasts between 3 and 5 years. If you wear the watch frequently in contact with water, perspiration, or humidity, durability reduces to 2-3 years. Milano Straps guarantees 18 months on straps crafted at the Casati Milano atelier, with replacement or maintenance options available.
