Strap for Aquaracer 300M Calibre 5 43 Stainless Steel / Blue / Steel

The TAG Heuer Aquaracer WAY201B.BA0927 features a lug width of 20mm. This dimension represents the distance between the metal pins that connect the bracelet to the case. To verify it, position your watch horizontally and measure internally the space between the attachments: this measurement is essential for selecting compatible aftermarket straps.

Alligator is the natural choice for this model, as its regular grain and natural lustre harmonise perfectly with the stainless steel case. Vegetable-tanned calf leather offers a more contemporary alternative with a soft texture. For those using the watch in aquatic environments, NATO straps in cordura technical fabric or silicone rubber maintain the original sports functionality.

The integrated bracelet of the WAY201B.BA0927 is connected to the case via extractable metal pins. Use a dedicated spring bar tool, position it perpendicular to the pin and gently press inward until the bracelet is released. Insert the new pins into the aftermarket 20mm strap and secure them to the case using the reverse procedure, ensuring they are fully inserted.

Yes, Milano Straps offers a wide selection of customisable 20mm straps in fine leather, technical fabric and rubber. All straps available online are compatible with the WAY201B.BA0927 and can be personalised in length, colour, initials and buckle type. For even more specific requirements, the Casati Milano atelier produces bespoke straps made to measure with direct consultation.

The lifespan of a leather strap depends on usage and construction quality. An alligator or vegetable-tanned calf leather strap, worn daily, maintains structural and aesthetic integrity for 2-3 years. Frequent exposure to salt water (given that the Aquaracer is water-resistant to 300 metres) can reduce durability; in this case rubber or technical fabric straps are preferable. Milano Straps guarantees 18 months on all bespoke straps from the Casati Milano atelier.
