Frequently asked questions

What is the lug width of the Pinion Pure PU22?

The lug width of the Pinion Pure PU22 is 22 millimetres. This standard, also called <a href="/pages/termine-glossario/misura-ansa">ansa measurement</a>, refers to the internal distance between the lug attachment pins. Precise measurement is essential before ordering a strap: position a calliper between the internal seating points from one end of the lug structure to the other.

What is the best strap for the Pinion Pure PU22?

The ideal strap for the PU22 depends on usage and aesthetic preferences. For daily versatility, a vegetable-tanned leather in dark brown develops authentic patina over time and creates refined contrast against the brushed steel case. For those seeking practicality, a NATO strap in heavyweight cotton maintains the minimal aesthetic and allows quick changes. FKM rubber represents the technical pure choice: guaranteed water resistance and maintenance-free operation.

How do you change the strap on the Pinion Pure PU22?

Removing the strap is a straightforward operation. Use a dedicated spring bar tool: insert the tip into the lateral access hole of the tension spring, lift gently until the spring retracts, then extract the pin. Repeat on the second side. The new strap is installed by aligning the pin with the seating points and pressing until the retention spring clicks into place.

Are aftermarket straps compatible with the Pinion Pure PU22?

Yes, all straps with a 22mm <a href="/pages/termine-glossario/misura-ansa">lug width</a> are compatible. This is a standard dimension that guarantees universal compatibility with contemporary artisanal straps. Milano Straps offers a complete collection of options in leather, NATO, and rubber for this measurement.

How long does a leather strap last on the Pinion Pure PU22?

A high-quality vegetable-tanned leather strap lasts an average of 5–7 years with regular maintenance. Longevity varies depending on frequency of use, climate conditions, and humidity exposure. The leather develops authentic patina over time, becoming a narrative element of the watch. Periodic maintenance with natural leather oil significantly extends longevity.
