Precision Deployant Clasp

Brushed/Polished Steel

None - strap only

Material: AnchorFLEX™ FKM rubber

Hardware: Compatible with our Standard Precision Deployant Clasp

Fitment: Made for Tudor Pelagos 39.

Also fits Black Bay Chrono 41 and 2nd generation Black Bay Heritage (22mm lug width).

A deliberately tight fit. We spec the end thicker than most straps for strength, so seating the spring bars takes more force than you might expect. That's by design — the fit loosens slightly after the first few installs and never gets sloppy. Take your time on the first fitting.

Attachment: Uses original Tudor bracelet end links, spring bars are included.

Length: 3-piece strap with 2 clasp ends (75mm/100mm) and one hole end (105mm) for maximum flexibility. Comfortably fits wrists from 5.25" to 8"

Important: This strap is designed for use with your original Tudor bracelet end links. Anchor end links are not included.

AnchorFlex™ End-Link Deployant

Integrated look. One-motion on and off.

Fits your Tudor Pelagos 39 using your original Tudor end links, with the case-hugging profile of the Flagship and a deployant clasp instead of a buckle.

Requires your original Pelagos 39 end links. They aren't included — spring bars are.

Built for the Precision Deployant Clasp

Same Flagship rubber, cut 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 a 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

Flagship 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.
