Product Overview
The Ewatchparts 18mm Italian Leather Watch Band is a carefully crafted replacement strap tailored for Franck Muller 5850 models with 18mm lug openings. Designed for discerning watch owners, this blue leather strap blends classic craftsmanship with practical functionality. Made from genuine Italian leather, it features a subtle embossed texture that enhances its visual depth while maintaining a refined, understated appearance. The 4.5mm padding throughout the strap provides a soft, cushioned feel against the wrist, significantly improving comfort during extended wear—whether at the office, during travel, or in casual settings.
Unlike generic watch bands, this strap is precision-engineered to match the exact specifications of the Franck Muller 5850, ensuring a seamless integration with the watch case. The attention to detail extends to the strap’s width, which measures 20mm at both ends, maintaining visual balance and structural integrity. The buckle end is sized at 16mm, allowing it to work with most standard buckles without modification. This thoughtful sizing ensures that the strap not only fits securely but also preserves the original aesthetic of the timepiece.
