Strap for Aquaracer 300M Quartz 32 Stainless Steel / MOP - Diamond / Bracelet

The lug width of the TAG Heuer Aquaracer WBD1314.BA0740 is 20 millimetres. This measurement represents the distance between the two horizontal pins protruding from the watch case. It is essential to measure this dimension accurately before ordering an aftermarket strap, as an incorrectly sized lug width will cause gaps or mechanical stress.

For the WBD1314.BA0740, we recommend three primary options: natural alligator for refined aesthetics and a patina that evolves over time; vegetable-tanned calf leather for a balance between breathability and longevity, with noble ageing characteristics; NATO fabric or vulcanised rubber to maintain the watch's aquatic vocation and ensure grip and practicality. Your choice depends on personal style and intended usage patterns.

To change the strap, follow these steps: 1) obtain a spring bar tool; 2) position the watch on a stable surface; 3) insert the tool into the small hole beneath the lug, pushing downward to release the pin; 4) repeat on the opposite side; 5) remove the worn strap; 6) align the new strap with the holes; 7) reinsert the pins until you hear a confirming click. If uncertain, consult a professional watchmaker.

Yes, aftermarket straps are compatible provided they strictly conform to the 20-millimetre lug width specification. Always verify technical specifications before purchase. Quality straps—such as those in natural alligator, vegetable-tanned calf, or technical fabrics—are fully compatible and offer customisation opportunities that the original bracelet does not afford. Milano Straps curates a comprehensive selection of 20mm straps optimised for sports watches like your Aquaracer.

Strap longevity depends on material and usage patterns. Quality vegetable-tanned calf leather, with proper maintenance (avoiding prolonged water exposure, protecting from dirt and excessive wear), typically lasts 3-5 years. Natural alligator, being denser and more precious, easily reaches 5-7 years. Leather ages nobly, developing a unique patina. Vulcanised rubber or NATO fabric straps last considerably longer, as they do not suffer from desiccation or cracking, reliably delivering 7-10 years with minimal maintenance.
