Strap for Aquaracer 500M Quartz 43 Stainless Steel / Black / Rubber

The lug width of the TAG Heuer Aquaracer WAJ1110.FT6015 is precisely 20 millimetres. This measurement is calculated between the internal lug attachments of the case, excluding the pin diameter itself. To verify it, position a millimetre ruler between the lug pins and measure the free space: you should obtain exactly 20mm.

The optimal strap depends on usage: for formal elegance, vegetable-tanned alligator in cognac or deep brown is recommended, as it develops natural patina over time. For frequent aquatic sports, vegetable-tanned calf offers durability and moderate maintenance. For absolute practicality, fluoroelastomer rubber or ballistic nylon straps guarantee salt-water resistance and UV durability, with rapid drying properties.

Place the watch on a soft flat pad or cloth. Using a fine spring bar tool, apply gentle upward pressure on the lower attachment pin from one side of the case, releasing the pin from its seat. Repeat on the opposite side. Remove the old strap and insert the new one, aligning the pins into both geminate seats. Ensure both pins snap into position with an audible 'click'.

Any strap with a 20-millimetre lug width is compatible with the WAJ1110.FT6015, regardless of material: alligator, calf, shell cordovan, rubber, nylon, suede. Always verify that the attachment pins have standard diameter (typically 1.8–1.9mm) and that the total length suits your wrist (consult our personalised measuring service).

Lifespan depends on leather quality and usage: vegetable-tanned alligator lasts 5–8 years with regular maintenance (quarterly cleaning, post-moisture drying). Vegetable-tanned calf resists 4–6 years if occasionally exposed to water. Fluoroelastomer rubber lasts 8–10 years without aesthetic deterioration. Casati Milano atelier offers 18-month warranty on all artisanal straps, with conditioning and restoration options available.
