ColaReb, a Rome-based Italian family business established in 1990, is well known for its meticulously handcrafted watch straps made in the Italian tradition of fine leatherwork. The company's hand-stitched leather and plant-based straps feature distinctive treatments and are designed and made entirely and exclusively in Italy using Italian materials. Every ColaReb product is one-of-a-kind, and as with any authentically handmade artisanal creation, slight imperfections and tonal variations add to the charm and rustic appeal of each unique piece.

All ColaReb products are made with 100% hypoallergenic, water-repellent linings and hypoallergenic stainless steel buckles. ColaReb collaborates exclusively with tanneries that operate in full compliance with the European Union's REACH regulations and standards, the most restrictive in the world in terms of consumer health and safety.

The Siena is integrated with handy quick-release spring bars. Prefer standard spring bars? Quick-release bars are easy to remove: simply slide the lever as far as you can to the left, then gently bend back the strap corner until the bar emerges from the slot.
