I bought two Timex Ironman 100 laps, I have over 3 years. I appreciate the ergonomics and possibilities, especially the various accounts rebour to split but 3 flats - The bracelet is rotten: I'm changing almost every year and each time, we must return it to Timex, 20 euros - It is true that the "split time" button is very sensitive, so that sometimes (far from all the time, anyway), even sleeveless, split time are false - I also had small problems to pile changes: loss of hétanchéité (but not serious, I was warned by the seller) but also buttons that are set to not walk (luckily I n 'had not changed the battery myself). Overall, a good product but a damper on the duration (I wear it all the time, I make forty to fifty km run per week)
