Curved Lugs Embossed Rectangular Alligator with calf Leather Base

You’d never realise it’s not alligator leather if we didn’t tell you. This range enables a good fit with its curved lugs profile for your watch.

RSM’s Embossed Alligator Leather range combines the visual richness of exotic leather textures with the practicality and versatility of premium calf leather. Sourced from a tannery in Shimeji City, Japan, each strap reflects generations of leather-processing tradition and meticulous Japanese craftsmanship, resulting in remarkably natural grain definition and an alluring tactile texture.

Each hide is painstakingly hand-finished to allow dyes to seep naturally into the grooves and contours of the embossed patterns, creating depth, tonal variation, and a more organic appearance. Unlike flat surface finishes, the multi-layered dyeing process enhances the relief of the grain, giving the leather a refined character that evolves beautifully with wear.

This range uses a particularly thin wrap around the spring bar to enable fitting onto dress and vintage watches with tight lug spaces. We also cater for classic timepieces with narrower lug widths, including 17.5mm configurations such as the Cartier Tank Vermeil and other heritage references that require precise fitment without compromising comfort or proportion.

The collection is offered in distinct grain profiles to complement different watch aesthetics. The rectangular grains bring a sharper, more architectural texture suited for modern luxury aesthetics.

By using embossed calf leather rather than relying on exotic leather farms, the range delivers the elegance and visual complexity of alligator-style textures with greater versatility, durability, and everyday wearability.

Behind The Design

Inspiration

Each hide is individually hand dyed after undergoing a carefully controlled embossing process. The result is a richly textured alligator grain with exceptional depth, softness and character.

Two distinct grain patterns. The Circular Grain or the Rectangular Grain for a completely different aesthetics from the same hide.

The tight stitch pitch is placed as close to the edge as possible, maximising the uninterrupted leather surface for the embossed pattern to shine. Thread colours are selected just one shade lighter than the leather itself, creating subtle definition that complements the grain without competing for attention.
