The Perrelet Turbine A1066/4 features a 20-millimetre lug width. This dimension is proportioned to the 47mm case diameter and provides access to a comprehensive selection of artisanal leather, NATO, and rubber straps.

How do you change the strap on a Perrelet Turbine?

Strap replacement on the Turbine A1066/4 is accomplished via the spring bars (removable lugs) positioned internally within the lug width. Use a dedicated spring bar tool to compress the spring and slide the bar horizontally. Verify that the new strap has a 20mm lug width to ensure proper fit.

Can I use an aftermarket strap on this model?

Yes, any strap with a 20mm lug width is compatible with the Perrelet Turbine A1066/4. We recommend verifying the exact width with a digital calliper prior to purchase. Milano Straps artisanal straps are tested for this dimension and available in multiple finishes.

How long does a leather strap last on sports watches like the Turbine?

Leather strap longevity depends on usage and maintenance regimen. On sports watches such as the Turbine A1066/4, with daily wear, a well-maintained alligator strap typically lasts 3–5 years. FKM rubber guarantees extended longevity (5–7 years), whilst robust cotton drap NATO can exceed 7 years with minimal wear.
