Choose options



The Mondaine Black Vegan Leather Watch Band 20 mm XL FG3120.20Q.XL offers extended comfort and ethical refinement, tailored for watches with 20 mm lug width. As part of Mondaine’s sustainable lineup, it is crafted from vegan leather and assembled under a CO2-neutral process, with up to 80% of factory power supplied by its own photovoltaic system. Designed for those needing extra length without sacrificing finish, this XL band ensures both style and fit.
Material & Appearance
The strap features outer black vegan grape leather with a matte texture that resists gloss, maintaining a clean, understated elegance. Edges are neatly finished to preserve silhouette clarity. The buckle and hardware are stainless steel, polished to a modest sheen that complements the strap’s subdued tone without dominating it.
XL Fit & Wearability
With XL length made to accommodate larger wrists, the band offers generous tail while retaining proportion along its 20 mm width. Flexible material moulds comfortably from the first wear, reducing break-in discomfort. Despite the larger size, the strap remains lightweight and agile, avoiding unnecessary bulk while maintaining secure engagement with the wrist.
Durability & Everyday Practicality
Vegan grape leather proves robust under regular use. The band resists sweat, fading, and wear from daily motion; occasional splashes or light moisture do not detract from its appearance. Easily cleaned with minimal maintenance, the material keeps its structure over time. A sturdy buckle ensures reliable fastening, even during active routines or frequent strap changes.
A Statement of Ethical Comfort
More than a mere replacement band, the FG3120.20Q.XL is a purposeful upgrade. It merges size flexibility, sustainable materials, and refined design—all in a format that prioritises comfort without compromising aesthetic integrity. Ideal for wearers who desire both ethical choices and an enhanced fit, it elevates both the look and wearability of compatible timepieces.
