AnchorFlex™ End-Link Deployant
Integrated look. One-motion on and off.
Fits your Tudor Black Bay 54 using your original Tudor end links, with a deployant clasp instead of a buckle.
Requires your original rivet-style end links. They aren't included — spring bars are. Not compatible with the 5-link bracelet end links.
Built for the Precision Deployant Clasp
Same geometry as the AnchorFlex Flagship, our original rubber strap — recut with 2-piece deployant geometry so it sits flush at the case and closes with a single motion. No threading the strap through a keeper every time you put the watch on.
Choose Strap + Precision Clasp to get everything you need, or strap only if you already own an 18mm Precision Deployant Clasp.
This strap is shaped for a deployant and won't work with a tang buckle. If you'd rather have a buckle, the AnchorFlex End-Link is the version you want.
Why FKM
FKM fluoroelastomer is what we build every AnchorFlex strap from, and it's why they last:
- Holds up to UV, heat, and chemicals
- Won't crack, fade, or go brittle with age
- Soft and pliable against the wrist, but structured enough to keep its shape
- No sagging or collapse the way cheap rubber does
Profile
- Clean modern lines with a subtle taper
- Substantial enough for daily wear, refined enough to dress up
- Built to complement a tool watch, not overpower it
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.
