Morellato has been making watch straps in Italy since 1930. This alligator-embossed calfskin strap is built to their standard — hand-finished edges, a comfort lining on the underside, and an emboss pattern with enough depth and consistency to read as genuine exotic leather at a glance. On the Speedmaster Professional's steel case and black dial, it shifts the watch's register entirely — from tool watch to dress chronograph — without changing a single thing about the watch itself.

Available in five colourways: Oxford, Slate, Espresso, Almond and Onyx. Each works differently against the Speedmaster's dial. Espresso and Almond warm the steel and draw out vintage character. Oxford and Slate sit clean and contemporary. Onyx matches the black dial and bezel for a monochrome profile that suits formal wear. Tapered from 20mm at the lug to 18mm at the buckle, with a brushed stainless steel buckle and comfort lining throughout. 20mm lug width.
