Red Hammered Calfskin Single Pass Watch Strap
A single piece of leather. No joins, no hidden weak spots under the watch case. The single pass design eliminates the traditional double structure: the strap passes entirely through the watch lugs, wrapping around the wrist in a single continuous strip of hammered calfskin.
The hammered finish is not decorative — it irregularly etches the leather surface, providing visual depth and a tactile grip that smooth calfskin does not offer. The red chosen here makes no compromises: it is a bold color, to be worn with conviction.
A contained thickness of 2.5mm allows the strap to remain flat under any type of bezel. Italian craftsmanship, with the attention to detail that distinguishes a strap made to last from one made to merely look that way.

A texture that hides daily life.

Frequently asked questions
Can I get this strap wet?
Yes, you can get it wet. It is an eco friendly model, made of Newlife® recycled polyester, obtained from plastic bottles, Made in Italy supply chain.
What is the hammered finish visible on the leather?
It is an engraving that makes the surface irregular. It is not an effect printed on top: it changes the grain and gives a different feel to the touch compared to smooth calfskin.
Does the strap have a central seam or is it a single piece?
It is a single piece, single pass. No joints, the leather runs whole through the lugs and wraps the wrist in one continuous strip.
What sizes are available in 18mm width?
For 18mm you will find two lengths: 20cm and 24cm. The other widths in the catalogue are 14mm, 16mm and 20mm, each with its own lengths.
How thick is it, and does it stay comfortable under the case?
The thickness is 2.5mm. It stays flat under any type of bezel, without adding bulk to the wrist.
