YOUR BRACELET IS NEVER THE PERFECT FIT
Morning: perfect. Afternoon: too tight. Evening: too loose. Heat, cold, and movement change your wrist — your bracelet can’t keep up.
On The Fly fixes that with instant, tool-free ±5 mm adjustment, completely hidden under your clasp. You’ll never see it, and neither will anyone else — except they’ll notice your watch always sits perfectly.

Luxury Craftsmanship – Same 316L stainless steel grade as Tudor, with a flawless aesthetic match.

Reversible – Install once, remove anytime, no trace.
Once you try it, every other bracelet will feel wrong.
Installs exactly like a factory link — no modification, no damage, fully reversible. Done in under two minutes with a 1.6 mm flat-blade screwdriver.
We don’t make “universal” links. Every Steel Reef component is individually designed for a specific Tudor reference and cut from the same grade of steel your watch is made from. Machined to ±0.02 mm, our links match OEM-inspired tolerances and finish so precisely that they disappear into your bracelet — the only difference is the improved comfort and balance. This level of precision takes time, expertise, and cost to achieve, which is exactly why serious collectors choose Steel Reef.
If it doesn’t look, feel, and fit like it belongs on your Tudor, send it back for a full refund.
We take pride in the exceptional quality and craftsmanship of our products, each inspired by OEM standards.
