The Heritage

The Perrelet Turbine A1051/1 is a 48mm stainless steel sports watch powered by the automatic P-331 caliber, displaying hours, minutes, and seconds. The model features the brand's signature rotating double helix visible through the dial, integrated lugs, and a 20mm lug width. This watch embodies Perrelet's philosophy of integrating the movement as a visual centerpiece, with a brushed steel finish that complements the central rotor's shine.

FAQ

What is the lug width of the Perrelet Turbine A1051/1?

The Perrelet Turbine A1051/1 features a lug width of 20mm, measured between the inner shoulders of the lug pins. This measurement is essential for selecting a compatible strap and ensuring a perfect fit with the case.

Which strap is best suited for the Perrelet Turbine A1051/1?

The Turbine pairs beautifully with alligator straps in tobacco or medium brown tones, which enhance the satin-finished steel case. For a more sporting approach, an anthracite NATO is excellent. For those desiring natural patina development over time, we recommend vegetable-tanned leather in chestnut. The choice depends on intended use and wearing context.

How do you change the strap on a Perrelet Turbine?

The A1051/1 features an integrated, non-standard lug. To change the strap, the lateral lug pins must be removed using a specialised tool (lug remover) or by consulting a competent atelier such as Casati Milano. The procedure requires care to avoid case damage.

Are aftermarket straps compatible with the Perrelet Turbine A1051/1?

Yes, quality aftermarket straps are fully compatible provided they respect the 20mm lug width. Milano Straps offers a certified collection of 20mm straps tested for the Turbine, guaranteeing correct fitting and the absence of unsightly lateral gaps.

How long does a leather strap last with daily use?

A quality leather strap, exposed to moderate-to-intensive use, maintains structural integrity for 3-5 years. With vegetable tanning, it develops a fascinating patina over time. Moisture and sun exposure accelerate ageing. We recommend rotating with other straps to extend durability and allow proper air-drying.
