Kumamoto ™ CTS End-Link Replacement Rubber Set

Refresh your Kumamoto system without replacing the entire assembly.

The Kumamoto CTS End-Link Replacement Rubber Set is a direct replacement for the original cut-to-size FKM rubber components used in the integrated Kumamoto CTS system.

Whether you’re rotating colors, replacing a worn set, or keeping a spare on hand, this is the same premium construction — built to integrate seamlessly with your existing Kumamotoend links and clasp.


Designed for the Kumamoto CTS System

These rubber segments are engineered specifically for the Kumamoto CTS End-Link configuration.

They maintain:

  • Precise end-link alignment

  • CTS trim-to-fit architecture

  • Clean integration with the Kumamoto clasp

  • Balanced wrist profile

This is not a universal rubber strap.
It is purpose-built for the Kumamoto integrated platform.


True Cut-To-Size Construction

Like the original system, this replacement set features CTS construction — allowing you to trim the strap to your exact wrist size before securing it with the deployant clasp.

Once sized, it wears tailored and streamlined, with no excess strap.


Premium FKM Rubber

Constructed from high-grade FKM rubber:

  • Resistant to heat, sweat, saltwater, and UV exposure

  • Flexible yet structured

  • Maintains shape and finish over time

  • Designed for long-term durability

Built for daily wear — not disposable use.


What’s Included

  • Left and right CTS rubber strap segments

  • Set of compatible spring bars for both the clasp and lugs.  

Not Included

  • End links

  • Deployant clasp

(This listing is intended for customers who already own the Kumamoto CTS End-Link system.)


When to Choose a Replacement Set

  • Switching to a new color

  • Replacing a worn or trimmed strap

  • Keeping a backup for travel

  • Refreshing your Kumamoto system


Built as a System

Kumamoto is engineered as a complete deployant platform — rubber, end links, and clasp working together.k

This replacement set preserves that precision while extending the life and versatility of your setup.

Customers praised this replacement rubber strap set for its "super high quality" and premium feel. Shoppers noted it "feels and looks premium" with excellent construction. However, some mentioned adjustment limitations, needing more holes near the spring bar for better clasp centering and fit customization.

Thank you for the wonderful product! For those considering Anchor Strap

Thank you for the wonderful product! For those considering Anchor Strap, then look no further, I highly recommend!

The quality of the material ( rubber strap for my Seiko) is superb! The fit to te watch itself is seamless; no gaps, no loose pieces, everything is on the button. Comfort is spot on as well - no pinch points; just comfort all around. Thanks Brando...keep cranking these out!

One of the nicest straps I have ever purchased

One of the nicest straps I have ever purchased. The strap is very comfortable, the clasp is top notched and it's a great color match to my Seiko Padi turtle. I would not hesitate to grab another when the need arrises.

Kumamoto is a winner!

I purchased the Navy Blue Kumamoto strap for my 41 MM Omega SMPC (2017 version). I couldn't ask for a better strap! The end links fit perfectly, the strap cuts to size with ease, and the comfort and utility of the strap is excellent. I've tried MANY straps and bracelets on the 41mm SMPC, but none have complimented the watch like the Kumamoto does.

Good product, very solid.

Like the product, looks great as advertised. Clasp is good and secure but doesn’t feel quite as premium as some others I’ve purchased.

Comfortable rubber strap with good end-link fitment on pre-2018 SMPc 41mm

Comfortable rubber strap with good end-link fitment on pre-2018 SMPc 41mm; no micro-adjust on clasp (w/minor sharp edges) and no quick release spring bars. Overall a good product that could be great with upgraded spring-bars and clasp with modern features.

Really nice…

Really nice perfect for my Seiko SKK GMT. End links are solid and high quality. FKM rubber strap also very nice. Just be carful of cutting to short, go 1 hole at a time. Remember short the 6 o clock side 😊.

I love this strap and want to give this strap 5 stars so damn bad

I love this strap and want to give this strap 5 stars so damn bad . Buckle is great , the look is amazing ,i love end links with rubber straps a ton . My only complaint is the rubber used for the strap . It’s super comfy but I already question the end that the spring bar goes through in the rubber . It’ stretches a lot and wouldn’t surprise me in a good snag the rubber breaks or in general wears quickly . If you could make the rubber hard like OEM omega straps it would be killer . Beyond that , i love this strap.
