Choose options


The Mondaine Black Vegan Grape Leather Watch Band 20 mm Extra-Long FG3120.20Q.L combines sustainability, comfort, and refined craftsmanship. Designed for watches with a 20 mm lug width, this strap employs vegan grape leather—a plant-based material derived from repurposed wine industry by-products—for a textured, ethical alternative to traditional leather. Produced under Mondaine’s CO2-neutral processes, the strap aligns environmental responsibility with design integrity.
Material & Finish
The outer surface displays smooth black vegan grape leather with a matte texture that resists gloss and highlights subtle grain. With no visible stitching, it preserves a clean, minimalist silhouette. A polished stainless-steel pin buckle adds subtle sheen, offering visual contrast while maintaining harmony with the strap’s refined aesthetic.
Fit & Extended Comfort
This Extra-Long version delivers a generous length (approximately 85 mm on the 12 o’clock side and 130 mm on the 6 o’clock side), enabling comfortable fit for larger wrists or those preferring additional strap tail. Despite its increased length, the strap remains lightweight and flexible, conforming easily to the wrist’s contours. Quick-release spring bars allow swift, tool-free adjustment or strap change.
Durability & Everyday Wear
Vegan grape leather withstands daily use well, resisting creasing, colour fade, and surface wear. While not intended for prolonged exposure to water, it handles occasional moisture sensitively. The brushed buckle secures firmly and preserves finish over time, even with frequent buckle adjustments.
A Statement of Ethical Elegance
More than a replacement band, the FG3120.20Q.L Extra-Long strap is a thoughtful upgrade for those who demand both style and conscience. It enhances any compatible watch with visual clarity, extended fit, and an eco-minded material choice. Ideal for wearers who value proportion, texture, and sustainability in each detail.
