The Flexibility Your Bracelet Deserves


If your bracelet feels too tight or too loose due to wrist fluctuations, our 'On the Fly' Extension Link provides the flexibility you need. Offering a quick, tool-free adjustment of +/- 5mm, this under-the-radar upgrade is hidden beneath the clasp, ensuring a perfectly balanced and comfortable fit. Whether adapting to changes in temperature, activity, or personal comfort, this is the solution you’ve been looking for.

Key Benefits:

  • Instant Adjustability: Easily adjust your bracelet length by +/- 5mm without tools—on the go, ensuring the perfect fit anytime, anywhere.
  • 100% Reversible & Damage-Free: This upgrade can be installed and removed with ease, leaving your watch and bracelet completely unharmed.
  • Effortless Installation: Installed once with a screwdriver, allowing for seamless, tool-free adjustments thereafter.
  • Under-the-Radar Upgrade: Hidden discreetly under the clasp, the extension link provides flexibility without disrupting the sleek look of your watch.
  • Tudor-Inspired Craftsmanship: Precision-engineered to meet standards inspired by Tudor OEM specifications, crafted from 316L stainless steel, with a flawless finish that perfectly matches your bracelet.

Enjoy the comfort, flexibility, and precision your watch deserves, with the luxury craftsmanship only Steel Reef delivers.
