Material & Ethical Design
Made from bio-sourced resin, this band reduces reliance on conventional plastics while maintaining toughness and flexibility. Its matte black surface presents a sleek silhouette that complements both polished and brushed watch heads. The use of sustainable materials positions this strap as a thoughtful choice for wearers who value environmental impact as well as style.
Fit & Wearability
Sized at 20 mm throughout, from lug width to buckle, the strap ensures visual consistency and balance. Making the band suitable for a wide range of wrist sizes. The resin material flexes comfortably, achieving a gentle feel soon after being fitted to the wrist—ideal for all-day wear without discomfort.
Durability & Everyday Practicality
Resin naturally resists water, sweat, and abrasion, making this strap especially useful for active lifestyles. The straight-mount design means clean integration with compatible cases, and the buckle closure locks securely into place. Though not intended for deep-immersion activities, it handles incidental moisture and daily wear without losing structural integrity.
A Statement of Function & Responsibility
More than just a replacement band, the FP16920-23B represents Mondaine’s commitment to balancing design, performance, and sustainability. It appeals to wearers who want both purposeful aesthetics and conscious material choices. With its resilient resin build, clean form, and ethical underpinnings, this strap enhances any compatible watch with style, comfort, and environmental awareness.
