Frequently asked questions

What is the lug width of the Pinion Pure PU01?

The Pinion Pure PU01 features a lug width of 22mm. This specific measurement ensures perfect compatibility with dedicated straps and should be measured using a digital calliper, positioning the measurement at the centre between the two pins of the case.

Which strap do you recommend for the Pinion Pure PU01?

For the PU01 we recommend two options: vegetable-tanned Italian or French leather for formal use, with tannage that ages naturally whilst maintaining sober aesthetics; NATO straps in technical nylon for intensive daily wear. The choice depends on context: office requires elegance, professional work requires durability.

How do I change the strap on the Pinion Pure PU01?

Obtain a spring bar remover tool or a small flathead screwdriver. Position the watch with the case facing upwards on a soft surface. Carefully insert the tool into the lateral slots of the case to push the spring bars: the strap will detach easily. Reinsertion requires precise alignment of the holes with the bars and gentle pressure until a click is heard.

Are aftermarket straps compatible with the PU01?

Yes. Any strap with a lug width of 22mm is compatible with the Pinion Pure PU01. We recommend verifying the strap thickness at the lug point: excessively thick straps may create lateral play, whilst straps that are too thin will not guarantee stability.

How long does a leather strap last on the Pinion Pure PU01?

A high-quality artisanal leather strap with vegetable tanning has a lifespan of 3-5 years with moderate daily use. Longevity depends on exposure to perspiration, water, and intensity of use. With regular maintenance (conditioning) and replacement with technical alternatives during summer, durability extends significantly.
