The Heritage

The Perrelet Turbine A1064/5 is a 44mm stainless steel sports-elegant watch powered by the automatic Perrelet P-331 movement with perpetual rotor. The signature dual twelve-blade turbine rotates on the dial, driven by natural wrist motion. The watch features a 20mm lug width, precise proportions that accommodate specialized straps without compromise. Hours, minutes, and seconds are displayed with certified precision on a satinized stainless steel case.

FAQ

What is the lug width of the Perrelet Turbine A1064/5?

The lug width of the Perrelet Turbine A1064/5 is 20 millimetres. This measurement is determined by the constructive geometry of the case and internal movement, representing the standard for this entire model series. Measurement is performed by positioning a ruler perpendicularly between the two terminals where the strap inserts into the case.

What type of strap is most suitable for the Perrelet Turbine A1064/5?

The Turbine A1064/5 performs optimally with high-quality leather straps, particularly vegetable-tanned calf or natural alligator. These materials allow genuine chromatic evolution over time and dialogue elegantly with the satin-finished steel case. Alternatively, a technical NATO strap in resistant fabric offers practicality for daily sporting use without compromising reliability.

How do you change the strap on a Perrelet Turbine A1064/5?

Strap replacement requires a specific tool called a spring bar tool. Insert the tool tip gently from the lower side of the lug, applying light pressure to release the internal spring securing the strap. Once one end is liberated, repeat the operation on the opposite side. Installation of the new strap follows the reverse procedure: insert one end of the spring into the lower lug first, then gently push until the spring clicks into the upper lug.

Are aftermarket 20mm straps truly compatible with the Turbine A1064/5?

Yes, any strap with a 20-millimetre lug width is compatible with the Turbine A1064/5, provided it respects the same nominal width. However, we recommend selecting certified quality straps from specialist horological suppliers: an economical strap in synthetic materials not only compromises the Turbine's aesthetics but may prove fragile and impractical. Milano Straps offers a curated selection of verified 20mm straps for this watch category.

What is the average lifespan of a leather strap for the Perrelet Turbine A1064/5?

A high-quality leather strap with vegetable tanning offers a lifespan of 3-5 years under normal daily use conditions. Longevity depends on factors such as solar exposure, ambient humidity, frequency of use, and maintenance. A shell cordovan strap, owing to superior fibre density, can remain functional for 7-10 years. It is advisable to alternate periodically between two or three straps to distribute wear and allow the material to regenerate naturally.
