You've heard of FKM rubber, but not all FKM rubber is created equal. Named for its notable water-resistant properties and flexibility, HydroFlex is Artem's FKM rubber formulation used in the construction of their finest straps. Engineered for the harshest of environments, getting the HydroFlex right is no easy task, involving an eight-hour mixing process and a dual-stage vulcanization at scorching temperatures. The HydroFlex requires absolutely zero break-in time straight out of the box, encircling your wrist like a well-worn leather strap.
Ideal for those who want the convenience of a bracelet but prefer the look and feel of a strap, Artem's Loop-Less system does not include a buckle. Instead, it is specifically designed for use with folding-style deployant clasps. Pair the Loop-Less strap with one of Artem's black or stainless steel Loop-Less deployant clasps or your OEM Omega clasp. Simply adjust the strap for your wrist size on your first use, and you won't need to do it again. Slip your wrist through the strap like a bangle and click the clasp shut (no fiddling with buckles necessary).

The perfect fit for my Omega 300. It's hard to find quality 21mm straps, and this was exactly what I was looking for. Amazing comfort, highly recommended. My one small complaint would be that there is no option for standard spring bars. I don't like seeing the 'nub' of the quick release from the front of the watch. Small issue, I'm still going to give it 5 stars.
I recently “went big” on a watch purchase to commemorate my late grandfather. The only prerequisite was that it had to be made in Germany, as my grandfather had a great affinity for the country. I settled on the Damasko DK32, and wanted to pair it with the best possible strap I could find. The Artem Hyderoflex is the highest quality strap I’ve ever seen. It’s flawlessly made and looks like a million bucks. Also, it’s not too long like so many of the rubber straps on the market. Yes, it’s crazy expensive, but when you spend almost 2k on a watch, it deserves the best! I definitely recommend it. Holben’s service was great. Thank you.
I've been purchasing watch straps for many years through Holben's. I've recently added several Artem straps, including a couple of Hydroflex, to my collection. Great straps and outstanding service, as always, from Holben's!
This is a very high quality, premium FKM strap. It is very comfortable right away. It is sporty and a dressy at the same time. Coupled with the loopless deployant clasp, it looks very sharp.
I bought this strap for my Speedmaster and it really pops against the dial. This is a solidly built strap that looks like it can stand up to whatever I can throw at it.
Nicely made. Good looking. Even the larger size has me at the last hole or two. Definitely not for wear over wetsuit or sweater.
This is an expensive strap, but now that it's on my wrist I can see why. I'm an industrial designer and I appreciate quality of materials and good design. The construction of the strap is pretty much flawless, and the attention to detail is impressive. The comfort level is beyond any strap I've tried.
This strap is not flexible or soft enough near the lugs, so it causes excessive pressure on the sides of the wrist. This probably depends on the shape and size of your wrist and the lug-to-lug size of the watch, but this strap is certainly not for me.
