The Autavia WBE5114.EB0173, seen from the bench

The TAG Heuer Autavia WBE5114.EB0173 is a modern reinterpretation of an iconic sports watch originally designed in the 1960s for pilots. The stainless steel case measures 42mm in diameter with a lug width of 20mm. It is powered by the TAG Heuer Calibre 5 movement, offering hours, minutes, seconds, and date display. The watch features a clean dial with applied indices, sapphire crystal, and water resistance suited for daily intensive use. The integrated bracelet functions as an organic extension of the case, distinguishing this model from traditional lug attachments.

Frequently asked questions

What is the lug width of the TAG Heuer Autavia WBE5114.EB0173?

The lug width of the TAG Heuer Autavia WBE5114.EB0173 is 20mm. This measurement is specific to the contemporary Autavia range and represents the standard interface between the 42mm case and the strap. Measurement should be taken from the inner edge of one lug to the other, ensuring precision during strap replacement.

Which strap is most suitable for the TAG Heuer Autavia WBE5114.EB0173?

For the WBE5114.EB0173, we recommend alligator in dark tones (black, dark brown) to maximise contrast with the stainless steel case and emphasise the racing heritage. Vegetable-tanned calf represents the versatile choice, ideal for those seeking evolved patina over time. NATO in ballistic fabric further amplifies the classic sports aesthetic. Rubber remains the technical solution for frequent water exposure.

How do I change the strap on this TAG Heuer model?

The WBE5114.EB0173 features integrated lugs requiring a spring bar removal tool. Position the tool in the micro-slot beneath the tension spring, apply controlled pressure to release the terminal, then extract the old strap. Insertion of the new strap follows the reverse procedure, verifying the absence of lateral play. For precision, Casati Milano's bespoke service provides accurate replacement with material selection consultation.

Is an aftermarket strap compatible with the WBE5114.EB0173?

Any strap with a 20mm lug width is compatible with the WBE5114.EB0173, regardless of material. However, we recommend verifying strap thickness (ideally 4-5mm) to ensure a clean interface with the case terminals. Milano Straps' artisanal straps are built to TAG Heuer specifications, guaranteeing optimal proportions and play-free fit.

How long does a leather strap last on a TAG Heuer Autavia?

A premium leather strap (alligator, calf, shell cordovan) on a chronograph subjected to moderate use presents an average lifespan of 3-5 years before replacement becomes necessary. Frequent exposure to moisture, perspiration and solar radiation accelerates ageing. Vegetable tanning tends to resist better than modern tanning due to more stable molecular structure. Casati Milano offers an 18-month warranty on bespoke straps, with regeneration possibility through leather reconditioning.
