Excellent service, fast delivery and great product. My watch looks awesome, keep up the good work guys...

QUALITY - Looks good and is genuinely waterproof. I use it on a Garmin fitness watch and have used it for swimming, kayaking, running and weight training with no apparent degradation. It's also much more comfortable than the silicone band that came with it.

I purchased this strap with a deployment, to use on a Citizen Titanium Red Arrows watch and I only wore it on special occasions. It did enhance the watches looks and was also water proof, though I have never swam or got it wet. It has lasted 5 years and the glue on the strap at the watch / pins has given up the ghost. The strap is still like new but it looks like the end bit near the pins is not stitched and this is why the small amount of glue has failed. I am going to attempt to glue and stitch the strap. I expect the strap to last a lot longer due to the occasional use of the watch.
