The Turbine A1047/1, seen from the bench

The Perrelet Turbine A1047/1 is a sports watch with a 44mm stainless steel case and 20mm lug width. It features the P-331 caliber movement equipped with the patented dual-rotor turbine system, where twelve blades rotate under gravity to power the watch without manual winding. Hours, minutes, and seconds are displayed on the dial, and the watch offers extended power reserve typical of Perrelet movements.

Frequently asked questions

What is the lug width of the Perrelet Turbine A1047/1?

The Perrelet Turbine A1047/1 features a lug width of precisely 20 millimetres. This measurement is consistent across all Turbine models with a 44mm case and ensures full compatibility with Milano Straps' complete range of 20mm artisanal straps. Measurement should be taken between the two anchoring lugs inside the case, perpendicular to the dial.

What is the best strap for the Perrelet Turbine A1047/1?

There is no single 'best' option, but rather three choices of excellence depending on your intended use. For sartorial elegance: alligator or shell cordovan with uniform tone and fine grain, which elevate the case finishing without competing with the turbine system. For daily versatility: vegetable-tanned calf leather, which develops natural patina over time and permits easy seasonal rotation. For extreme performance: double-layered nylon ripstop NATO or structured rubber, ideal for aquatic environments where maintenance must remain minimalist.

How do you change the strap on the Perrelet Turbine A1047/1?

Strap replacement is straightforward and requires no specialised tools. Position the watch with the dial facing downward on a soft surface. Locate the two lug pins on either side of the case (connection points between case and original strap). Use a pin remover tool (often provided with artisanal straps) or a small screwdriver to gently push the first pin outward, sliding the original strap free. Repeat on the opposite side. Insert the pins through the new strap's lugs, ensuring perfect alignment, and push them inward until they click into position. Verify that the strap sits equidistant from the case on both sides before wearing.

Is an aftermarket strap truly compatible with the Perrelet Turbine A1047/1?

Yes, provided the declared lug width is precisely 20mm. Milano Straps' artisanal straps are manufactured to Swiss manufacturing tolerances, guaranteeing a perfect fit without excessive play or tension. Compatibility is assured across A1047/1 models from any production year, as Perrelet has maintained this lug width consistently throughout the Turbine line. Always verify the measurement before purchase by consulting detailed product specifications.

What is the average lifespan of a natural leather strap on the Perrelet Turbine A1047/1?

A high-quality artisanal leather strap—alligator, calf, or shell cordovan—maintains optimal functionality for 3 to 5 years with moderate daily wear and regular maintenance (monthly cleaning, conditioning every six months). Actual durability depends on environmental factors: humidity, direct sunlight, and perspiration accelerate aging. Wear manifests initially as tonal variations (desired patina) and subsequently as micro-creasing in surface grain. NATO and rubber straps, free from natural organic material, maintain structural characteristics unchanged for 7 to 10 years, with wear limited to predictable surface scratching.
