The Pure PU02, seen from the bench

The Pinion Pure PU02 is a 42mm timepiece with bronze and stainless steel case, featuring the ETA caliber 6498-1 movement. It offers essential functions: hours, minutes, and small seconds subdial. The 22mm lug width maintains proportional harmony between the case diameter and strap attachment, following classical watchmaking proportions. The bronze case develops an organic patina over time through natural oxidation and wear.

Frequently asked questions

What is the lug width of the Pinion Pure PU02?

The Pinion Pure PU02 features a lug width of 22mm. This dimension is critical for strap compatibility: it must measure exactly 22mm between the two inner terminals of the case. Verifying this measurement before purchasing a strap is essential to ensure functional compatibility.

Which strap do you recommend for the Pinion Pure PU02?

The choice depends on intended use and aesthetic preference. For classical elegance, we recommend a vegetable-tanned alligator or vegetable-tanned calf leather; for daily sportive wear, a heavy-canvas NATO strap; for practicality in humid environments, an FKM rubber strap. All our 22mm straps are engineered to enhance the proportional design of the PU02.

How do I change the strap on the Pinion Pure PU02?

The Pinion Pure PU02 uses fixed lugs. To change the strap, remove the lugs from the case using a spring bar remover tool to compress the internal spring and slide them out. Insert the lugs into the new strap, ensuring they are fully secured. If you lack experience, we recommend contacting an expert: Casati Milano offers strap-changing services by appointment.

Which aftermarket strap is compatible with the PU02?

Any strap featuring a 22mm lug width is compatible with the Pinion Pure PU02. Milano Straps offers a curated selection of 22mm straps: alligator, calf, shell cordovan, NATO, and rubber. All are equipped with standard spring-bar lugs, guaranteeing complete compatibility and straightforward installation.

What is the lifespan of a leather strap for the PU02?

A leather strap's lifespan depends on usage, tanning method, and environmental conditions. A quality vegetable-tanned strap, worn daily, maintains full functionality for 3–5 years before significant aesthetic wear appears; the wrist-contact zone typically wears first. Shell cordovan straps offer superior longevity (5–7 years of intensive use) due to the fibre density of the leather. To extend lifespan, avoid prolonged moisture exposure and occasionally apply castor oil to nourish the leather.
