The Heritage

The Perrelet Turbine A1047/4 is a 44mm stainless steel 316L timepiece featuring the automatic Perrelet P-331 caliber with hours, minutes, and seconds functions. Introduced in the mid-1990s, the model is distinguished by rotating vanes activated by wrist motion, creating a perpetual dynamic illusion. The 20mm lug width accommodates structured straps and maintains visual balance with the case diameter. Water resistance is rated at approximately 100 meters, suitable for daily wear.

FAQ

What is the lug width of the Perrelet Turbine A1047/4?

The lug width of the Perrelet Turbine A1047/4 is 20mm. This measurement is critical for selecting compatible straps and represents the internal distance between the two pins that attach the strap to the case. A strap with non-matching lug width will result in mounting difficulties and potential damage to the lugs.

Which strap is recommended for the Perrelet Turbine A1047/4?

For the Turbine A1047/4, we recommend straps in vegetable-tanned alligator (brown or black), vegetable-tanned calf leather with natural patina, shell cordovan, or ballistic nylon NATO 20mm for versatility. The choice depends on wear context: leather straps enhance the elegant character, whilst NATO and rubber options emphasise the sporty dynamic. All must conform to the 20mm lug width specification.

How do I correctly change the strap on a Perrelet Turbine A1047/4?

Use a professional spring bar removal tool. Position the tool in the groove of the spring bar and push towards the centre until the pin releases. Remove the old strap and insert the new one by aligning the holes with the pins. For the Turbine A1047/4, we recommend consulting a certified watchmaker or Atelier Casati Milano to ensure maximum mounting precision.

Can I use an aftermarket strap on the Perrelet Turbine A1047/4?

Yes, provided the strap is compatible with 20mm lug width. Verify that the internal width between the holes corresponds exactly to 20mm. The finest aftermarket straps are crafted from premium leather with vegetable tanning or integrated deployante buckles. Ensure the strap thickness is proportionate to the 44mm case diameter.

How long does a leather strap last on the Perrelet Turbine A1047/4?

A high-quality leather strap with vegetable tanning has an average lifespan of 3-5 years with daily wear. Longevity depends on humidity, frequency of use, and maintenance practices. An alligator or shell cordovan strap, thanks to denser fibres, can last 7-10 years. Rotating between multiple straps significantly extends the useful life of each one.
