A stand-out in the RIOS1931 catalogue, the KALUGA combines the sporty style of a racing strap with its large triple perforations, with the novel look and feel with specially birch-tanned Russia leather.
The strap comes in a selection of six natural colours, each outfitted with a contrasting cream-white stitch along the edge. A superb secondary strap for those looking to really change up the look of their watch.
