A LITTLE GUIDANCE

Make the right choice.

How do I choose the right size?
LUG WIDTHLONG SIDEBUCKLE SIDELENGTH
  1. Between the lugs.

    Measure the inside distance between the two attachment points on your watch, in millimetres. This is your lug width.

  2. Two halves, one fit.

    Measure both halves of a strap you already wear comfortably, excluding the buckle. Compare those measurements with the selected size.

  3. Check the buckle.

    The strap can taper from the lug to a narrower buckle. Check the buckle width if you plan to reuse existing hardware.

The complete sizing guide

For Apple Watch, choose your case size and adapter colour. For Samsung, choose your watch model so we can match its attachment.

When will my strap arrive?

Production takes 7–10 business days. Shipping takes 7–14 days after dispatch. These are separate estimates, not a guaranteed arrival date.

How should I care for this leather?

A sporting rhythm.

Rally perforations are part of this strap design. Look at the size and placement of the openings in this product’s photographs, alongside its taper and stitching.

Choose your watch connection, lug width and strap length in the fitting options above. A compatible connection matters as much as the appearance of the strap.
