Our Story
2024
While searching for replacement straps for their own watches, Alex and Spencer encountered a market dominated by cheaply produced products, misleading marketing, and brands prioritising speed and margins over quality and longevity.
Rather than accept compromise, the decision was made to build what was missing.
The Build
2025
Founded and manufactured in Manchester, United Kingdom, Geneva Watch Straps committed to doing things properly from the start.
Over 19 months dedicated to research, prototyping, and refinement. More than 100 individual samples were produced and tested.
Only premium grade materials were selected, including high grade FKM rubber and watch grade leather, chosen for their durability, comfort, and long term performance.

Unlike standard rubber or silicone, FKM does not crack, fade, or become sticky over time.
It is non-allergenic, odour-resistant, and maintains its shape and finish even with daily wear, making it the finest rubber available for high-end watch straps.
