Artem's HydroFlex combines a sailcloth-textured upper with an FKM rubber base that feels noticeably more flexible than many traditional sailcloth sport straps. Unlike stiff layered constructions that require break-in, the HydroFlex bends easily from first wear while retaining the water resistance and durability expected from rubber. The textured surface keeps the strap visually restrained compared to heavily patterned dive straps, making it especially effective on modern tool and sport watches.

Material & feel

The HydroFlex uses a hybrid construction with an FKM rubber base bonded to a sailcloth-embossed upper. FKM rubber is known for its resistance to heat, moisture, and daily wear, making it suitable for swimming and humid conditions. The embossed surface provides the appearance of sailcloth without the water absorption associated with fabric straps.

The strap contains no animal-derived materials and is entirely vegan. Hardware includes an Artem-branded brushed stainless steel pin buckle, and quick-release spring bars allow the strap to be installed or removed without tools.

This is my 4th Artem loopless

This is my 4th Artem loopless. The quality and lack of break in make them my go-to set up on a few of my watches

Exactly what i was looking for.

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.

Excellent Strap

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.

Overall, I am impressed with this strap. It is comfortable, looks great, and feels noticeably better than Artem’s original PVC sailcloth straps. The price is high—higher than it probably should be—but I do not regret the purchase. I plan to wear it every day, so it will be interesting to see how well it holds up over time. I use it with a Formex adjustable deployant and I like this setup a lot.

The watch band is exactly as advertised. Holben has been superb. Delivered on time and everything exactly as advertised. Highly recommend!

hi everyone ,
I would just like to say that both the hydro flex sailcloth watch strap and the Artem deployant clasp are great products - so far I'm very happy with them.

Another Great Artem Strap From Holben's

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!

Best strap I have ever bought

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.

You get what you pay for

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, short

Nicely made. Good looking. Even the larger size has me at the last hole or two. Definitely not for wear over wetsuit or sweater.

Thanks for the feedback; good to hear the build and look worked well. Landing at the last holes can happen depending on wrist size and fit preference. It’s helpful for other customers to have that context.

Incredibly comfortable strap that's built like a tank

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.

Too tight

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.

Hi Rouslan, thanks for the feedback. The HydroFlex has a more structured build near the lugs to support the case, so it can feel firmer in that area, especially on smaller wrists or watches with a longer lug-to-lug span. Fit can vary depending on wrist shape and how the watch sits. For those looking for a softer, more flexible feel right at the lugs, a thinner or more pliable strap is often a better match. We appreciate you sharing your experience.
