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

The lug width of the TAG Heuer Aquaracer WBD1322.BB0320 is 20mm. This measurement is specific to the compact 32mm case and is critical for the visual balance of the watch. To verify correctly, measure the distance between the two spring bar holes: it must be exactly 20mm. Straps of 18mm would hang loosely, whilst those of 22mm would not seat correctly in the attachment lugs, potentially damaging the case.

The best strap depends on intended use: black alligator is the classic and formal choice, harmonises perfectly with the satinised steel case and develops a natural patina over time. Vegetable-tanned calf leather offers a friendlier character and ages beautifully. For genuine diving, structured rubber is the only legitimate choice. NATO fabric provides tactical practicality and tool-free changes. Shell cordovan is the exclusive option for those who appreciate the noble ageing of leather over years, developing mahogany-coloured reflections.

Strap replacement on the WBD1322.BB0320 is straightforward but requires precision. Position the watch on a soft cloth with the caseback facing you. Using a dedicated spring bar tool, gently push the small spring pin inward to release the tension. Extract the pin completely and remove the old strap. Align the new strap's holes with the attachment lugs, then reinsert the spring pin, ensuring the clip engages securely on both sides. Verify the strap is firmly seated before wearing the watch.

Yes, absolutely. The WBD1322.BB0320 accepts any quality 20mm artisanal strap. Aftermarket straps offer far greater material variety (alligator, calf leather, shell cordovan, vegetable-tanned hides) and customisation options than original straps. Ensure the new strap is dimensioned specifically at 20mm and that its fastening system is compatible with the standard spring bars fitted to the case.

Leather strap lifespan depends on material quality, usage patterns and maintenance. An artisanal-grade alligator or calf leather strap typically lasts 4–6 years with regular wear (4–5 days weekly). Constant exposure to chlorine, saltwater and UV rays accelerates deterioration. Shell cordovan lasts slightly longer (6–8 years) due to leather density. To extend strap life, avoid prolonged contact with chlorine and seawater, apply leather conditioner every 6–8 months, and store in a cool, dry environment.
