FAQ

What is the lug width of the Perrelet Turbine A1085/1A?

The lug width (distance between the lugs) of the Perrelet Turbine A1085/1A is precisely 22mm. This dimension is specific to the 48mm case proportions. To verify, use a digital calliper and measure the internal distance between the lug shoulders. This measurement ensures exact compatibility with aftermarket straps.

What is the best strap for the Perrelet Turbine A1085/1A?

For the Perrelet A1085/1A, we recommend an alligator strap dyed in depth (black, dark brown, or navy blue), as the granular texture naturally dialogues with the visual motion of the Double Rotor. Alternatively, vegetable-tanned calf leather with honey or tobacco patina introduces warmth whilst maintaining sobriety. For sporty contexts, a robust NATO in graphite grey emphasises the model's contemporary character.

How do you change the strap on the Perrelet Turbine A1085/1A?

The Perrelet Turbine A1085/1A features an integrated steel bracelet, not a simple strap. Replacing it with a 22mm strap requires removing the original bracelet through the pins and lugs—a procedure demanding specific tools and precision. We recommend consulting an authorised service centre or experienced watchmaker to avoid damage to the case.

Is the Perrelet Turbine A1085/1A compatible with aftermarket 22mm straps?

Yes, the Perrelet A1085/1A is fully compatible with aftermarket straps of 22mm lug width. It is essential to verify the exact measurement (22mm between lug shoulders) prior to purchase. Milano Straps offers a complete selection of 22mm straps in premium materials: alligator, calf leather, NATO, rubber—all ready for shipping and customisable online.

How long does a leather strap last on the Perrelet Turbine A1085/1A?

The durability of a leather strap depends on the material and usage. Vegetable-tanned calf maintains structural integrity for 3–5 years with regular wear, whilst alligator, being more robust, can extend longevity to 4–7 years. The patina that develops naturally is desirable, a testament to the intimate relationship between watch and wrist. Periodic maintenance (gentle cleaning, conditioning) prolongs strap life.
