About FKM Rubber:
FKM, or fluoroelastomer, is an extremely durable rubber compound with excellent resistance to salt water, aggressive chemicals and extreme temperatures (-45Β°C to 300Β°C). These properties make FKM an excellent material for a rubber watch strap, combining outstanding resistance and durability with an elegant and refined appearance.
How to Choose the Correct Size:
To order the correct watch strap and ensure a proper fit for your watch, it is important to measure the lug width beforehand. Simply measure the distance between the lugs of your watch case. The distance in millimetres corresponds to the watch strap size you need. The image below illustrates how to take this measurement.

How to Install the Watch Strap:
Our replacement watch straps feature Quick Release spring bars, making installation quick and easy. Once you receive your new watch strap, follow these simple steps:
- Position one end of the spring bar into the corresponding hole on the watch lug.
- Gently press the Quick Release lever to retract the spring bar and position the other end into the opposite lug hole.
- Release the lever and make sure the spring bar is securely in place. Repeat the process on the other side of the watch.

NorteSpring seems like the best kept secret yet to be discovered.
Their Tropic strap is amazing quality.
The FKM rubber is very comfortable, the detail in the texture is fantastic and the branding on the hardware is subtle.
The price is reasonable, which is very difficult to find on any other brand/companies commercializing Tropic like straps.
I never understood how can someone charge 75$ plus for a FKM rubber strap. I think I have found my people, reasonable and serious.
Highly recommend NorteSpring for the way they have handled the business and this particular product for its great quality.
Thank you very much.
Cheers
