The Turbine A1050/1, seen from the bench

The Perrelet Turbine features the brand's Calibre P-331 with hour, minute, and second indications. The model is distinguished by the double rotor mechanism that creates a continuous visual movement effect on the dial. The A1050/1 reference belongs to the characteristic collection of the Swiss brand founded in the 18th century.

Frequently asked questions

What is the lug width of the Perrelet Turbine A1050/1?

The lug width of the Perrelet Turbine A1050/1 is precisely 22 millimetres. This measurement is determined by the proportion between the 48mm case diameter and the structural thickness of the titanium-stainless steel lugs. The 22mm dimension ensures perfect visual balance between the substantial dial and the wrist extension, without overloading the model's silhouette.

What is the best strap for the Perrelet Turbine A1050/1?

There is no single 'best' strap in absolute terms, but rather materials suited to specific contexts. For formal settings, shell cordovan with vegetable tanning and brown or mahogany patina creates synergy with the visible rotating mechanics. For daily wear, vegetable-tanned calf leather with medium grain offers comfort and durability. For sports or marine environments, FKM technopolymeric rubber protects the titanium from oxidation. Your choice depends on the balance between aesthetics and function you wish to achieve.

How do I change the strap on the Perrelet Turbine A1050/1?

The Turbine A1050/1 is fitted with standard horn lugs with spring bars. To change the strap, first remove any protective guard if present. Use a spring bar remover tool to gently compress the pin on each lug by levering inward toward the case middle. The pin will retract, allowing you to slide out the old strap. Insert the new one by aligning one side first, then use the spring bar remover to compress the other side and click the pin into place. Verify that both sides are securely fastened before wearing the watch.

Can I use an aftermarket-compatible strap with the Perrelet Turbine A1050/1?

Yes, any strap with a 22mm lug width is completely compatible. Milano Straps offers an extensive collection of handcrafted straps in leather, textile and rubber, all engineered for this precise dimension. Always verify that the strap eyelets are correctly sized to accommodate 22mm spring bars without excess play. A quality aftermarket strap does not compromise your watch movement and allows you to personalise your Turbine's appearance according to context and season.

What is the typical lifespan of a leather strap on the Perrelet Turbine A1050/1?

Leather strap longevity depends on material quality, construction craftsmanship and conditions of use. High-quality leather (shell cordovan, alligator, vegetable-tanned calf) subjected to moderate wear can last 3-5 years before internal fibres weaken and the strap thins near the buckle. More economical leathers last 1-2 years. Constant exposure to humidity, perspiration and temperature fluctuations accelerates deterioration. Keeping your leather strap clean, lightly conditioned with natural oils, and stored in dry environments significantly extends material lifespan.
