  1. THE Superior Dive Watch Strap 5 Star Review

    Posted by on 8th Aug 2017

    I wear a vintage Scubapro 500 automatic dive watch, a classic collectible from the late '70's. Its original ISOfrane rubber strap finally gave out after all these years. The new ISOfrane replacement straps is just as sturdy and comfortable as the original, and looks identical. First-rate product.

  2. Super comfortable, great looking strap!! 5 Star Review

    Posted by on 26th May 2017

    Recently I bought a Seiko "Blue Lagoon" Samurai dive watch - it has a medium-blue dial, and a little turquoise on the bezel. So what better way to complement it than with a turquoise Isofrane strap??! It looks amazing!! Feels even better. This strap is so comfortable I could wear it for a week straight and hardly know anything was on my wrist. It is simply beautiful, and well made. My Seiko is truly eye-catching when on this strap!!!

  3. The only rubber dive strap you should have on your dive watch!!!!!!!! 5 Star Review

    Posted by on 16th Apr 2017

    I have purchased more than 25 isofrane straps mainly the basic blach with the classic brushed rs buckle is my favorite! I have the 20mm and the 22mm size I never really needed the 24mm for any of my SEIKO or DOXA wtches! Isofranes may cost alittle more than the lookalikes- (BUT TRUST ME ONCE YOU BUY AND FEEL THE ISOFRANE AMND THE RS BUCKLE AND HOW FLAT AND COMFY THE BUCKLE SITS YOU WILL BE HOOKED!--TRUST ME BUY ONE AND YOU WILL BE CONVINCED! ISOFRANE THE BEST AND THE ONLY ORIGINAL RUBBER DIVE STRAP YOUR DIVE WATCH SHOULD HAVE ON IT! "ISOFRANE-THERE IS NO SUBSTITUTE-PERIOD END OF DISCUSSION!

  4. A good investment 5 Star Review

    Posted by on 4th Apr 2017

    I purchased a black Isofrane strap to replace the similar looking strap that came on my Armida A7. I upgraded because the OEM strap wasn't as comfortable as I would have liked; it was stiffer/less pliable. The Isofrane solves that problem, and it also anchors the watch better without having to over tighten the strap (which is needed particularly for this Armida model). As for the vanilla scent, I didn't notice a scent on the Isofrane. The Armida strap had a noticeable vanilla scent at arm's length, and while I liked it, I appreciate the neutral (nearly absent) scent of this Isofrane. Beyond these points, I agree with the other positive reviews you read here. You won't be disappointed with an Isofrane.

    I have many ISOFRANES all of my straps are black with the BRUSHED RS BUCKLE- My straps are 22mm and 20mm for all my SEIKO DIVERS and my (1) loved DOXA 1200T PROFFESIONAL which is on a black 20mm RS buckle ISOFRANE! tJHERE MAY BE COPYS OF ISOFRANES OUT THERE FOR LESS MONEY, but trust me none come close to the fit and finish and comfort and style and especially the BRUSHED RS BUCKLE ON THE CLASSIC BLACK STRAP- A MATCH MADE IN HEAVEN! The only strap I have on all my dive watches are ISOFRANES with the excecption of my CASIO DW6900-IV G-SHOCK watch which I have the stock strap which suits the liteweight watch just fine and is my watch I can just wear and not tjhink about damaging it! But my BELOVED SEIKO DIVERS & AND MY (I) DOXA all live on ISOFRANE 20MM & 22MM black ISIOFRANE STRAPS WITH THE BRUSHED RS BUCKLE! Please dont make the mistake and save money to buy a lookalike isofrane copy, nothing feels like an original one and only ISOFRANE RUBBER DIVE WATCH STRAP! Wotth every penney! Some people think they are too much money for a rubber strap, but pleasde trust me they are wiorth every penney you will realize once you wear one! GREAT GREAT GREAT GREAT STRAP!

  6. the best rubber band of the world without any doubt 5 Star Review

    Posted by on 3rd Feb 2017

    After several trials with different rubber bands (included the genuine OEM straps of several prestigious brands) I can affirm that the best rubber band that you can buy for your watch is the isofrane one.
    The rubber is no too soft and not too hard, the manufacturing is perfect and the buckles are safe and confortable. It costs the right for the quality that it offers. Moreover buy with trust because the guys that works there are kind and serious and reply to any questions and needs very quickly.

  7. Expensive, but well worth it. 5 Star Review

    Posted by on 5th Oct 2016

    This strap exudes a feeling of top quality & thoroughness of design. The rubber itself is soft & flexible while feeling tough & durable. The 'ladder" design allows the skin to breath for added comfort. The keepers can be slightly difficult to engage, but do not wonder once aligned.
    Easily recommended.......

  8. The only strap that belongs on s serious dive watch!!!!!!!!!!!!!!!!!!!!!!!!!! 5 Star Review

    Posted by on 19th Sep 2016

    This is my 25-30 ISOFRANE strap and I think I have said all I can say about hoe GREAT GREAT these straps are! I personally like to go for the traditional black strap in either 22mm or 20mm with rthe brushes RS BUCKLE! VERY NOSTALGIC!!! But you cant go wrong with a beautiful nato green or blue or the eye catching beautiful orange! I personally like the feel of the RS BUCKLE more than the IN BUCKLE BUT BOTH ARE FANTASTIC! Trust me forget about price and buy one and I promise you will never change to another strap!!!

  9. amazing quality 5 Star Review

    Posted by on 15th Sep 2016

    I was a bit skeptical when ordering, even though I've only heard good things....well they are all true! Incredible fit, quality, the band doesn't slip at all, really chamged the look of my watch and will wear it more more now as i didnt like the strap it came with.
