Kumamoto™ End-Links
Precision-machined stainless steel end-links
Seamless case integration. Zero-compromise fit. Built for the Kumamoto™ system.
Engineered for Integrated Fit
Kumamoto™ End-Links are designed to transform your watch into a fully integrated platform.
Each set is engineered around model-specific lug geometry and case curvature, delivering a precise, gap-free fit that follows the original case lines—not a generic aftermarket approximation.
This is system-level engineering.
Why They’re Different
Model-Specific Fitment
Designed for exact case geometry—not universal compromise. Each version is tailored to a specific watch platform for a true integrated fit.
316L Stainless Steel Construction
CNC-machined from solid 316L stainless steel for strength, structural integrity, and long-term durability.
Curvature Matched to Case
Precision-contoured to follow the natural transitions of your watch case, preserving flow from lug to strap or bracelet.
System Integration
Engineered to integrate seamlessly with:
- Kumamoto™ Bracelet
- Kumamoto™ FKM Strap
- AnchorFLEX™ Flagship End-Link Strap
Switch between steel and FKM without replacing your core hardware.

FAQs
AnchorFLEX™ straps are made from premium FKM rubber and have been third-party tested to be free of harmful fluorinated “forever chemicals” within the scope of the testing performed. We do not intentionally add PFAS-based coatings, surface treatments, or chemical finishes to our straps. Because FKM is a fluorinated rubber, we avoid vague blanket claims and clearly disclose the material. Customers who prefer to avoid fluorinated rubber entirely may prefer our nylon, sailcloth, leather, or other non-FKM strap options.
Some end-link installs can feel tight at first because the thickness rubber strap at the end-link is maximized to ensure durability. There are a few ways to get it installed:
First, try gently wiggling and pushing the spring bar through until the spring bar pops into the opposite side of the end link. This can require some effort.
You can also squeeze the rubber portion of the strap into the end link between your thumb and index finger while pushing the spring bar into place. This helps compress the rubber slightly and gives the spring bar more room to seat properly.
If those techniques do not work, our premium 1.7mm spring bars can be used as an alternative. There is no downside to using them, but we recommend trying the first two installation methods first since the standard spring bars usually work once everything is seated correctly.
If you still have trouble, contact us and we can help troubleshoot the install.
