The clock I have for 6 months and the clock itself is great. Unfortunately, this usually comes from the bracelet. The tape is easily processed into loose. A Rekamation at tomtom brought a lot of email correspondence but no solution. After the glass is now broken, because the clock is once again fallen out of the belt is broken the clock. If repaired with costs of Tomtom. I do not recommend you buy as long as the issue is not resolved with the bracelets.
