The Heritage

The TAG Heuer Autavia WBE511A.BA0650 is a contemporary reinterpretation of a 1962 aviation chronograph. It features a 42mm stainless steel 316L case with black ceramic bezel and is powered by the TAG Heuer Calibre 7 automatic movement with hours, minutes, small seconds and date. Water resistant to 100 metres, the watch accommodates a 20mm lug width, a dimension reflecting the case proportions and TAG Heuer's construction standards for this sports watch family.

FAQ

What is the lug width of the TAG Heuer Autavia WBE511A.BA0650?

The lug width of the TAG Heuer Autavia WBE511A.BA0650 is 20 millimetres. This is the space between the two lugs (pins) on the case and determines strap compatibility. A digital calliper allows you to verify the measurement with precision.

What is the best strap for the TAG Heuer Autavia WBE511A.BA0650?

The choice depends on usage and aesthetic preference. Black alligator offers elegance and develops a natural patina over time; vegetable-tanned calf provides softness and classic Italian aesthetics; NATO fabric echoes the historical avionic heritage. All materials are compatible with the 20mm lug width.

How do you change the strap on the TAG Heuer Autavia WBE511A.BA0650?

Remove the strap by pushing the two lateral case pins inward with a spring bar tool until the internal spring compresses. Once the pin is extracted, the old strap comes free. Installation of the new strap follows the same process in reverse: position the new strap on the pins, insert the pin, and the spring locks into position.

Is an aftermarket strap compatible with the TAG Heuer Autavia WBE511A.BA0650?

Yes, any strap with a 20mm lug width is compatible with the WBE511A.BA0650. Artisanal straps from Milano Straps are constructed with this measurement and guarantee correct positioning without lateral play.

How long does a leather strap last on the TAG Heuer Autavia WBE511A.BA0650?

Durability depends on usage, climate, and leather quality. A first-grade alligator strap maintains structural properties for 5–7 years of daily wear; vegetable-tanned calf tends to show faster wear in bend zones. Regular maintenance—cleaning with a damp cloth, natural air-drying, and biannual conditioning—significantly extends strap lifespan.
