Size (lug/buckle):

Swiss company ISOfrane initially launched this classic dive watch strap in the early 1960s. Its innovative design and material quickly made it a favored choice among the most renowned dive watch manufacturers of the 1960s and 1970s.

Reintroduced by Synchron in 2010, ISOfrane straps are now made in Italy using an improved proprietary isoprene rubber compound for even better durability and softness. These vanilla-scented straps are 100% silicone-free, hypoallergenic, and waterproof. With a ribbed underside to prevent adhesion to skin and large slots for ventilation and water drainage, they are also non-toxic and do not attract lint or dust like silicone straps.

Material:

  • Isoprene rubber (100% silicone-free).
  • ISOfrane's Retrosicuro buckle in either brushed stainless steel or black DLC (diamond-like carbon) finish.

Sizing:

  • Available in 20mm and 22mm.
  • Thirteen sizing holes to achieve the perfect fit.
  • Piece length 130mm / 75mm excluding buckle.
  • Total length approximately 8" excluding buckle.
  • Thickness tapers from 5.5mm at lug ends to 3.5mm at opposite ends.

Includes:

  • One free pair of strong, seamless double-flange stainless steel spring bars.
FAQ

Q: Do you sell watch bands for women?
A: We do! Many of our short-length straps are the perfect size for women.

Q: Can you suggest a strap that looks amazing with my watch?
A: Unfortunately, because the range is so vast (and personal taste is subjective), we cannot advise regarding aesthetic suitability for specific models and styles of watches.

Q: I have an Apple watch. Will any of your straps work for me?
A: Sure! Our handy Apple watch band adapters accommodate most 22mm straps.

Q: Are spring bars available?
A: Yes, for each strap that is not already integrated with quick-release spring bars, we include one free pair of strong, seamless double-flange stainless steel bars.

Q: What strap size do I need?
A: To determine your size, use a metric ruler to measure the internal distance (in millimeters) between the lugs of your watch.

Q: My Bonetto Cinturini deployant strap is too long. Can you help?
A: Of course! See our Bonetto Cinturini sizing guide for cutting instructions.

Q: Do you offer international shipping?
A: Yes! Visit our Shipping & Returns page for more information.

Isoftane Seiko Tuna

I bought this new Seiko Yellow Tina, wanted a yellow Isofrane strap to go with it. I turned to Holbens because of price, they were able to post to Australia.
It’s a very comfortable strap, the yellow strap smells like vanilla, where as my black Isofrane doesn’t!

The strap arrived before my watch did, fitting it was easy. It’s only a weekend watch for me.
The keepers with the Isofrane are very snug, & I must position them in place before putting it on.
In all, I’m very happy with the strap, & am looking at another purchase in future with Holbens.

The best diver strap you can buy

The ISOFrane is about as nice of a strap as you can get for a dive watch. It's comfortable, the keepers are well designed, and it's breathable on the wrist. Highly reccomended.

Heavy duty

Amazing strap for comfort on hot summer days. Made of thick rubber. I don’t really notice the “vanilla smell” some people are talking about. Only thing I’d change would be the length of the strap. It’s almost too long even on my 7.5” wrist. Oh and the price is pretty steep but you get what you pay for. Like usual, the strap shipped very fast.
