We believe the Borealis rubber straps are the best rubber straps available in market for diver watches taking into account the quality/price ratio and majority of our customers agree with that.
This rubber strap is the result of over a year of work developing a new vulcanized rubber formula that brings what a rubber strap should be about: durable, flexible, vintage looking and affordable.
The Borealis Rubber Strap 20mm Blue has a size of 130/75 mm, a diameter of 20mm and is made of vulcanized rubber. Its composition does not contain any kind of silicone just rubber though it is flexible as a silicone rubber without attracting dust.
It is in our opinion the best vulcanized rubber strap in market for diver watches taking into account the quality/price ratio.
