AnchorFlex Pro – Deployant FKM Strap
The First of Its Kind. Designed by Anchor.
Introducing the AnchorFlex Pro — the world’s first "pass-through" FKM rubber strap designed specifically for a deployant clasp. This isn’t a rehash of existing designs—it’s an Anchor original, engineered from the ground up to combine the slim profile of a single-pass strap with the clean, secure closure of our custom deployant system.
Crafted from the same soft-yet-durable AnchorFlex™ FKM rubber found in our original lineup, the Pro edition brings a new level of comfort and adaptability to your wrist. At just 1.5mm thick with 10 micro-adjustment holes, it delivers a near-custom fit with a clean silhouette—whether you’re in the water or on the move.
And for existing customers: this strap is fully compatible with our nylon deployant clasp, so you can easily swap colors or upgrade your setup without buying a new clasp.

Love the look of this single pass FKM, it has great texture and feels premium. However, the deployant simply is not very comfortable. It's fine most of the time, but if anything presses against the clasp, it digs into your skin more than a butterfly or any other deployant I've used. Still a great product 95% of the time. I probably would go back and buy the version that has a normal clasp if I had a redo.

Very nice strap! I had doubts that FKM rubber would be pliable enough for a full pass. To the contrary, the strap is quite flexible and looks better than a NATO (which everyone has). The clasp is OK, a little sharp on the edges, but is very secure and easy on/off. I plan on ordering another in 22mm.

I love the flex pro! What a great strap! Very comfortable and easy to install into the clasp. I like to use curved spring bars for single pass straps. I use this strap on an Omega Speedmaster and a Tudor Ranger. I definitely will buy other colors.

The band is super soft and comfortable and the clasp is solid and well built. Will be buying more in the wider sizes
