The Heritage

The Perrelet Turbine A1074/2 is a 47mm stainless steel chronograph featuring the P-361 caliber beating at 28,800 vph. It displays hours, minutes, seconds, date, and chronograph function. The distinctive rotor rotates freely in front of the dial. The lug width is 20mm, proportioned to the case geometry and integrated lugs.

FAQ

What is the exact lug width of the Perrelet Turbine A1074/2?

The Perrelet Turbine A1074/2 is fitted with 20mm lugs, a dimension that reflects the proportional geometry of the 47mm case. Measurement should be taken internally, between the spring bar seats, excluding the lug thickness itself. All straps available on Milanostraps for this width have been tested to ensure perfect compatibility with the Turbine's integrated lugs.

What is the best aftermarket strap for the Perrelet Turbine A1074/2?

Choice depends on intended use and aesthetic preference. For formal settings, an alligator strap with vegetable tanning or shell cordovan offers visual refinement. For daily technical-sports use, a cotton NATO or FKM rubber strap ensures durability and practicality. For absolute versatility, a natural brown calf leather ages elegantly whilst maintaining visual harmony with the satin steel case.

How do you change the strap on a Perrelet Turbine A1074/2?

The change requires a spring bar removal tool with a forked tip. Position the tool between the lug and the pin, lifting gently to release the internal spring. Once the pin is extracted, the old strap slides away. Insert the pin into the new strap, aligning it with the lug seats, and press until you hear the locking click. Repeat on the opposite side. It is recommended to consult tutorial videos for the first time or contact a specialist service.

Are Milanostraps straps fully compatible with the A1074/2?

Yes. All 20mm straps available in the Milanostraps catalogue have been selected and verified for full compatibility with the Perrelet Turbine A1074/2's lugs. The attachments fit perfectly into the case's original spring bar seats, with no play or unintended stress. Every order is dispatched with detailed installation instructions.

How long does a natural leather strap last on a Perrelet Turbine A1074/2?

Durability varies based on material, frequency of use, and maintenance. An alligator or vegetable-tanned calf strap typically resists 3–5 years of daily wear, ageing progressively towards warmer tones. Shell cordovan, thanks to superior density, can reach 5–7 years. Deterioration accelerates if exposed to moisture, direct heat, or intense perspiration without periodic cleaning. Apply natural wax every 6–12 months to significantly extend leather life.
