No clasp system. No complexity. Just a clean, locked-in look.
AnchorFLEX™ FKM Performance
Built from our signature AnchorFLEX™ FKM fluoroelastomer, this strap is made for real-world wear:

- Won’t crack, fade, or degrade over time so you can feel confident that your watch will stay attached to your wrist
- Soft, flexible feel with a structured, premium finish
- Designed to hold its shape—no cheap rubber collapse
This is performance material, elevated.
Flagship Design
The Flagship design is all about balance:
- Clean, modern profile with subtle taper

- Designed to complement tool watches—not overpower them
It’s the strap you leave on.

FAQs
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.
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.

Awesome strap, comfortable, lines up perfectly to the case, would recommend as a great alternative to the oem seamaster fitted rubber strap
A
Perfect strap. Wonderfully supple and looks OEM.
S
The fitment is great and it gives the timepiece a whole new look. Extremely comfortable.

I really like this.. wish this has extra hole for my 6.5 inch wrist fit tightly.. or shorter one choice.
B
Great fit to the original end links and looks incredible! Definitely going to be my summer combination!
K
I was surprised how much I ended up loving this strap. The end links fit perfectly, the texture of the rubber looks great and it’s an extremely comfortable strap. I rarely wear any other strap on my SMP 300 anymore. Another benefit of this strap system is that if you buy Anchor’s oyster bracelet for the 41mm Omega Seamaster, you can use it on the 42mm SMP 300 using the 42mm end links. I find it is also better quality than Forstner’s oyster bracelet.

Perfect rubber strap for the Seamaster. End links fit perfectly, rubber strap is soft and super comfortable. Watch wears wonderfully. I really like the design of the buckle. It feel very low profile and smooth to the touch on the wrist. If you’re looking for a rubber strap, this is the one.
S
Great Quality and style !!
V
An excellent strap. The endlinks fit perfectly and give it a luxious look to it. The only critique I have is that the second catcher needs a tab so that it doesn't slide off the extra strap length. If you're thinking about it do it!
W
Really looks good on the blue Tudor Black Bay 54. Fits great and looks OEM
R
That is better than on the photo. Perfect match.
Z
Great feeling strap that fits my omega seamaster very well. However, getting the spring bars through the endlink and rubber strap was extremely difficult. I had to use pliers to force the spring bar through the holes scratching the spring bars.

Made my watch new again, made me stop looking at other watches. Now that a huge win!
