The Aquaracer WBP1180.FN8027, seen from the bench

The TAG Heuer Aquaracer WBP1180.FN8027 is a 40mm titanium sports watch from the historic Aquaracer line, combining Swiss diving instrument tradition with material innovation. It features the TAG Heuer TH50-00 chronometer-certified movement with 4Hz frequency and 80-hour power reserve, offering hours, minutes, seconds, date function, and chronograph. The titanium case provides superior wearability while maintaining structural rigidity, and develops a characteristic patina over time. The 20mm lug width is precisely determined by the case geometry and attachment pin configuration.

Frequently asked questions

What is the lug width of the TAG Heuer Aquaracer WBP1180.FN8027?

The lug width of the TAG Heuer Aquaracer WBP1180.FN8027 is 20mm. This measurement is defined by the distance between the two spring bars that attach the strap to the case. It is essential to verify that the strap is exactly 20mm, as incorrect sizes (18mm or 22mm) will not fit properly and will compromise aesthetic alignment with the case edges.

Which strap is recommended for the WBP1180.FN8027?

For the WBP1180.FN8027, we recommend straps in alligator with vegetable tanning or calf leather in cognac, tobacco, and deep black tones. Alligator leather offers subtle elegance and complements the brushed titanium finish perfectly. For intensive water use, FKM or EPDM rubber straps provide durability and practicality. NATO straps in high-tenacity polyamide are ideal for hot climates and casual occasions.

How do I change the strap on a TAG Heuer Aquaracer?

Changing the strap on the WBP1180.FN8027 is performed using a dedicated spring bar tool to compress the small attachment pins on both sides of the case. Once the pins are released, the original strap detaches easily. The new strap is secured by inserting the pins into the case slots until the click of closure. The procedure requires care to avoid scratching the case; we recommend having it performed by a specialist atelier such as Casati Milano.

Are aftermarket straps compatible with the WBP1180.FN8027?

Yes, any strap with a 20mm lug width is compatible with the WBP1180.FN8027, provided that the spring bar diameters match and the attachment is free from proprietary bearings or mechanisms. Milano Straps offers artisanal 20mm straps specifically designed to ensure total compatibility with the standard lugs of this TAG Heuer model.

How long does a leather strap last on the WBP1180.FN8027?

The lifespan of a leather strap depends on the tanning method used and environmental conditions. A high-quality alligator strap with vegetable tanning typically lasts 3-5 years with daily wear; the leather develops progressive patina without loss of functionality. Vulcanised rubber straps have longer durability (7-10 years), whilst NATO polyamide straps can last indefinitely. The Casati Milano atelier guarantees its straps for 18 months, covering manufacturing defects.
