Strap for Autavia Calibre 7 Twin Time Stainless Steel / Blue

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.

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.

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.

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.

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.
