Where the Silver and Gold models carry metal bracelets, the Black Leather model introduces contrast: a gold-plated case against a black leather band. The warmth of gold against the formality of black leather creates the most versatile piece in the series — equally at home in a formal outfit and an everyday one.\u003c\/p\u003e\u003cp\u003eThe case is stainless steel with gold-colour plating, 27mm x 18mm, Roman numeral dial. The band is genuine cowhide leather in black, adjustable from 11.5cm to 15.5cm — a narrower fit range than the metal bracelet models, suited to smaller wrists. Solar movement, Japanese caliber, assembled in China. Daily life water resistance.\u003c\/p\u003e\u003ch2\u003eKey Features:\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGold x Black — Gold-Plated Case, Black Leather Band\u003c\/strong\u003e: The contrast colourway of the series.
