AnchorFlex™ End-Link Deployant
Integrated look. One-motion on and off.
Fits the 42mm Seamaster Diver 300M with milled 316L steel end links and a deployant closure.
Fits 42mm Seamaster Diver 300M models (current generation).
End links and spring bars are included. Nothing to source, nothing to salvage off a bracelet.
Milled 316L End Links
Machined from solid 316L stainless and cut to the Seamaster's case profile, our end links close the gap at the lugs so the strap sits flush the way a bracelet does. No sourcing OEM parts, no hunting eBay for a spare set — everything you need to mount it is in the box.
No Size to Choose
Deployant straps usually make you guess at checkout — short or long, and hope you picked right. We ship all three pieces instead: two clasp ends at 75mm and 100mm, and a 105mm hole end. Combine the pair that fits and you're done. No measuring your wrist, no wondering which variant to order, no exchange if you guessed wrong the first time.
Built for the Precision Deployant Clasp
Same geometry as the AnchorFlex Flagship, our original rubber strap — recut so it hugs the case and closes with a single motion. No threading the strap through a keeper every time you put the watch on.
The Precision Deployant Clasp is sold separately. If you already own our 18mm clasp, this strap drops right onto it.
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.
