This excellent silicone rubber watch strap with tyre tread motif is  manufactured by the Zuccolo Rochet company who were established in Switzerland over 100 years ago.

Available in 4 sizes to fit watches with 18mm, 20mm 22mm or 24mm pins the strap features a strong 3 fold or deployment clasp with a safety over-lock and a small pin ladder length adjuster
Larger length adjustments are effected by simply cutting off sections of the strap at the clasp end

Silicone rubber watch straps which are of course totally impervious to water will remain soft and comfortable and will not tend towards going harder with age as will resin and rubber types

At its longest the strap is 18.5cms long
Add the size of your watch case to compare to your wrist size.
