The smallest component in your watch setup is often the one carrying the greatest responsibility.
Steel Reef OEM Replacement Spring Bars are manufactured to the original dimensions and tolerances specified for each compatible model, providing a direct replacement for worn, damaged, or fatigued spring bars. Precision-machined and thoroughly inspected, they are designed to restore the secure fit and reliability your bracelet was intended to have from day one.
Unlike generic alternatives that can vary in diameter, shoulder dimensions, or overall fit, our spring bars are engineered for specific watch references to ensure proper engagement within the lugs and bracelet end links.
Because when it comes to protecting your watch, the details matter.
We offer reliable worldwide shipping, and orders are carefully processed and dispatched with tracking details provided. If for any reason you are not satisfied with your purchase, you may return it within 14 days of receipt, provided the item is unused, in its original packaging, and in resalable condition. Please note, we cannot accept returns for used items. Refunds or exchanges will be processed once the return has been received and inspected.
All Steel Reef products come with a comprehensive 3-year warranty, covering manufacturing defects in materials and craftsmanship under normal use. If an issue arises within this period, simply contact our team and we will repair or replace the item at no additional cost. This warranty reflects our commitment to quality and ensures peace of mind with every purchase.
Every Steel Reef component is precisely engineered and thoroughly inspected.
In the rare event of a manufacturing fault or a genuine fit issue, we’ll take care of it with a replacement.

Fits and Looks OEM!
The on-the-fly link is the perfect accessory to my vintage “meters first” 5513. The bracelet now fits perfectly in warm or cold weather. Before, it had to be compromise-adjusted to be too loose for warm and a bit tight for cold. The link material and finish match perfectly also, and indistinguishable from OEM.

Fits perfectly
The extension link was easy to install and fits my Tudor Heritage Chrono perfectly. No more tight fit. I will buy for some of my other watches.
