Strap for Aquaracer 300M Quartz 35 Stainless Steel / Diamond / Blue MOP / Nylon

The lug width of the TAG Heuer Aquaracer WAY131N.FT6091 is 20mm. This dimension is measured as the distance between the two spring bars that connect the strap to the lugs on the side of the case. The spring bars have a diameter of approximately 1.5mm.

The optimal strap depends on your intended use. To emphasise the diving heritage: FKM rubber with textured surface for water grip. For everyday versatility: black alligator with raw silk stitching. For refined elegance: vegetable-tanned calf leather in neutral tones (navy blue, taupe, grey). For water activities: ballistic nylon NATO strap in khaki or anthracite grey.

The strap is changed by removing the two spring bars (pins) that fix it to the case lugs. Using a spring bar tool, push the pin inward into the case until one end is freed from its seat. Repeat on the other side. Insert the new strap's pins into the lug holes, ensuring they click firmly into position. The operation takes approximately 2-3 minutes with practice.

Yes, the WAY131N.FT6091 is fully compatible with quality 20mm aftermarket straps. It is essential to verify that the lug seats are correctly dimensioned: the case lugs are 20mm wide and between 2.8 and 3.2mm thick. The handcrafted, customisable straps from Milano Straps are calibrated to these specifications and guarantee a perfect fit.

A quality leather strap (alligator, vegetable-tanned calf) typically lasts 3-5 years with moderate daily wear, provided it receives regular maintenance: gentle cleaning with a slightly damp cloth, air drying, occasional application of neutral wax to maintain flexibility. Frequent water exposure reduces longevity; in such cases, an FKM rubber strap offers superior durability (5-7 years). Milano Straps warrants its bespoke straps for 18 months from creation.
