Frequently asked questions

What is the lug width of the TAG Heuer Autavia WBE5110.EB0173?

The lug width of the TAG Heuer Autavia WBE5110.EB0173 is precisely 20 mm. This measurement refers to the distance between the two lateral lugs (pin attachments) that connect the strap to the case. Verifying this dimension before purchasing an aftermarket strap is essential, as an incorrect lug width will not fit properly into the case lugs.

Which type of strap is best suited for the TAG Heuer Autavia WBE5110.EB0173?

The WBE5110.EB0173 pairs exceptionally well with vegetable-tanned alligator straps, which develop a natural patina over time and reflect the vintage-contemporary aesthetic of the model. Fine-grained calf leather in dark shades (brown, black) offers daily comfort and longevity. For intensive technical use, FKM rubber straps deliver extreme resistance. Ballistic NATO straps provide maximum versatility and quick-change capability.

How do I change the strap on a TAG Heuer Autavia WBE5110.EB0173?

Obtain a spring bar tool (specialized lever with flat tips). Place the watch on a soft surface. Insert the spring bar tool tip beneath the metal pin (spring bar) connecting the strap to the case, applying gentle inward pressure until the pin retracts. Remove the old strap. Repeat on the opposite side. Insert the new strap by aligning the pins with the case lugs and pressing until both pins lock into position with an audible click.

Can I use an aftermarket strap on this watch?

Yes, provided the lug width is exactly 20 mm. High-quality artisanal straps are compatible with the WBE5110.EB0173. Choose straps crafted by specialized artisans, where lug construction precision and attachment accuracy guarantee perfect fit and multi-year durability. Straps featuring a deployante (safety clasp) offer enhanced daily comfort.

How long does a leather strap last on a watch like the WBE5110.EB0173?

A quality leather strap (vegetable-tanned alligator or premium calf) typically lasts 5–7 years with regular use, accounting for the fact that leather is a living material that naturally ages and develops patina. Longevity depends on usage frequency, exposure to moisture and sunlight, and maintenance practices. Occasional conditioning with specialized balms extends service life. Technical rubber straps offer comparable lifespan but maintain consistent performance in extreme conditions.
