Strap for Aquaracer 300M 35 Ceramic / White / Bracelet

The TAG Heuer Aquaracer WAY1391.BH0717 features a lug width of 20mm. This measurement is the precise standard for the 35mm case and is essential when selecting aftermarket compatible straps. Always verify that your replacement strap is specified for 20mm, as this dimension ensures a perfect fit without play or undesired stress on the case lugs.

Your choice depends on usage and personal aesthetic. For marine elegance with minimal maintenance, alligator leather with natural grain offers unique patterns and organic light reflection. If you prefer a patina that develops with time, vegetable-tanned calf leather in cognac-brown tones creates harmony with a dark blue dial. For frequent sports or water use, structured rubber is waterproof and moisture-resistant. Shell cordovan, conversely, is ideal for wrists alternating between formal and casual contexts, delivering a finish with substantial visual depth.

The WAY1391.BH0717 uses standard TAG Heuer spring bar attachments. You'll need a spring bar tool and good lighting. Insert the lever under one lug, gently press to release the spring, then extract the bar. Repeat on the opposite side. When installing your new strap, align the attachment points with the case lugs and press until you feel the spring click into position. To avoid scratch risk, a qualified watchmaker or Casati Milano atelier can execute the replacement with millimetre precision.

Any strap with a 20mm lug width is compatible with the WAY1391.BH0717. milanostraps.it offers a comprehensive collection of 20mm straps in diverse materials: alligator, calf, rubber, NATO and shell cordovan, all ready for dispatch and customisable. Each strap is tested to ensure correct lug positioning without play. For a bespoke experience with personal leather selection and finishes, Casati Milano crafts custom straps with an 18-month warranty.

Leather strap longevity depends on frequency of use, humidity exposure and tanning method. A quality vegetable-tanned calf strap typically lasts 3–4 years of daily wear. Alligator, owing to its natural fibre structure, tends to sustain itself longer (4–5 years). If frequently exposed to saltwater (relevant given the Aquaracer's aquatic DNA), durability may decrease. Structured rubber, conversely, exceeds 5 years under intensive sports use. To extend any strap's lifespan, apply a water-repellent treatment every six months and store it away from direct sunlight.
