Frequently asked questions

What is the exact lug width of the Perrelet Turbine A1075/1?

The Perrelet Turbine A1075/1 features a lug width of 20mm. This is the international standard measurement for compatible straps: any strap specified as 20mm will fit perfectly between the lugs without requiring any modification.

What is the best strap for the Perrelet Turbine A1075/1?

There is no single optimal choice as it depends on intended use and personal aesthetic preference. For formal occasions, we recommend alligator or vegetable-tanned leather in dark brown tones; for sporting everyday wear, technical rubber or cotton NATO provide comfort and practicality; for those seeking visual patina and tactile softness, vintage-finished French calfskin is unparalleled.

How do I change the strap on my Perrelet Turbine A1075/1?

The Turbine is fitted with integrated lugs featuring removable spring bar pins. Use a dedicated spring bar tool to gently lift the pin from the opposite side: the old strap will release easily. Insert the new strap by aligning the holes with the pins and press until the pin clicks into position. Verify the strap is securely attached before wearing.

Can I fit an aftermarket 20mm strap on the Perrelet Turbine A1075/1?

Yes, absolutely. Any artisanal or manufactured strap with a 20mm lug width specification will be compatible. Milano Straps curates a collection of leather, rubber and synthetic material straps specifically tested on this case diameter, guaranteeing both mechanical compatibility and aesthetic harmony.

How long does a leather strap last on the Perrelet Turbine A1075/1?

A quality leather strap, subject to regular maintenance (gentle cleaning and conditioning every 6–12 months), lasts 3–5 years of daily wear. Longevity depends on exposure to moisture, perspiration, UV radiation and frequency of use. Given a timepiece of this calibre, we recommend rotating multiple straps to distribute wear.
