This is perhaps the nicest digital watch I’ve ever had, the watch is new, but it came broken, the alarm does not sound or better to say sounds so low, it is inaudible, is practically useless, do not know if it can be fixed, I’ll have to take you to a technician, the problem is that I am in Ecuador, I do not know if the guarantee will serve or can be returned. ------------------------- Este es quizás el reloj digital más bonito que he tenido, el reloj es nuevo, pero me vino averiado, la alarma no suena o mejor dicho suena tan bajo, es inaudible, es prácticamente inservible, no sé si se pueda arreglar, voy a tener que llevarle a un técnico, el problema es que estoy en Ecuador, no sé si sirva la garantía o se pueda devolver.

Great buy! But stopped working after 3 months

Color: Green

Great buy! Bought this for my husband and he loves it! I got him the dark green one. It’s stylish but still durable for physical activities like construction. Also it is completely waterproof which is great. Can be left on for showers or pools. Edit 3 months later it stopped working. Sent it to the manufacturer and they will hopefully send a new one or fix it.

Cheap Quality - 3 MONTH wait for warrantied repair!

Color: Black-Red/Digital/Black

About 40 days into my purchase, the watch starts doing a complete reset when I try to reset the timer, making me have to reset the date and time again. The Analog watch isn't any more reliable -- sometimes it will just stop temporarily and start again. I'll look at my watch and see the analog time, then realize it's 15 minutes behind actual time. So I called Timex for a warrantied repair. They told me I could send it in and it would take them about 3 MONTHS to repair it and get it back to me. 3 MONTHS, because they have to forward it to the Philippines for repair via the cheapest means possible. That is a ridiculous about of time to wait on a warrantied repair.
