The Turbine A1086/1, seen from the bench

The Perrelet Turbine A1086/1 is a 48 mm stainless steel watch featuring the P-331 automatic caliber with visible double-helix rotor on the dial. The 20 mm lug width accommodates the case proportions and ensures visual harmony. This model combines Swiss watchmaking heritage with contemporary design, featuring satin-finished steel construction that develops a natural patina over time and meets Swiss chronometry standards.

Frequently asked questions

What is the lug width of the Perrelet Turbine A1086/1?

The Perrelet Turbine A1086/1 features a lug width of 20 millimetres. This dimension is standard for the Turbine family and is determined by the width of the stainless steel case lugs. To verify the compatibility of a strap, simply measure the distance between the inside of the lugs from wall to wall using a calliper or precision ruler.

Which type of strap is best suited for the Perrelet Turbine A1086/1?

The Turbine A1086/1, with its 48-millimetre diameter and technical design, pairs ideally with straps in alligator, shell cordovan, or high-quality calf leather. These materials, preferably crafted using vegetable tanning, develop a patina over time that enhances the case's satin finish. For a more sporting approach, robust NATO fabric straps or structured FKM rubber are excellent choices. Your selection depends on the context of wear: leather for formal occasions, NATO and rubber for informal settings.

How do you change the strap on a watch with 20mm lugs?

Strap replacement requires a specialised tool known as a spring bar tool. Insert the flat end of the tool into the lateral grooves of the lug, applying gentle pressure to compress the spring inside. Once the spring is compressed, the lug withdraws from the case. To install the new strap, align the strap's holes with the lugs and, using the same tool, compress the spring to seat it into the holes. Gradual, deliberate pressure prevents damage to both case and strap.

Is an aftermarket strap compatible with the Perrelet Turbine A1086/1?

Yes, any strap with a 20-millimetre lug width is compatible with the Perrelet Turbine A1086/1, regardless of the manufacturer. Artisanal straps of quality, crafted from noble materials such as alligator, shell cordovan, or vegetable-tanned Italian leather, represent an excellent choice for personalising your watch according to your aesthetic preferences and context of use. We recommend verifying that the strap has been constructed using solid techniques and refined finishes to ensure durability comparable to the timepiece itself.

How long does a leather strap last on the Perrelet Turbine A1086/1?

The lifespan of a leather strap depends on material quality, tanning method, and environmental conditions. An alligator strap with vegetable tanning, subject to regular maintenance (periodic cleaning and conditioning with specific balms), maintains structural integrity for 5–10 years. Shell cordovan, denser and more robust, can exceed 15 years of use with proper care. Italian calf of excellent craftsmanship ensures durability between 4 and 7 years. External factors such as prolonged exposure to humidity, extreme temperature fluctuations, and neglected maintenance significantly reduce these timeframes. A NATO fabric strap in technical materials maintains full functionality for 3–5 years, whilst FKM rubber assures 8–10 years of intensive wear.
