Awesome old-school 1990's feel
Color: Black/Black/Digital
besides the timer than can be set to do interval training, and the 100 lap memory, there is also a cute memo function that can store 10 memos, with 3 pages each. I use to help me remember my children's phone numbers.

Nostalgia is costly.
Color: Black/Black/Digital
It’s a nice watch but in no way is it worth the price. You’re paying a huge nostalgia fee with this one. At best this is a $40 watch. Battery life is horrible (3 years) and it loses 1-2 seconds a day. For a digital quartz watch that is extremely poor. I thought mine might be a poor example but after researching online I found the majority of new flix owners report losing at least 1-2 seconds a day. As a Casio fan, it’s hard to see what the draw is to Ironman watches. Casio has them beat in almost every category. The only thing I think the timex wins at is the screen legibility at extreme angles. Anyways, I got it because I had a flix in high school and it brings back some memories. I believe the nostalgia factor is why these watches have any appeal at all.

The watch has a problem with the alarm.
Color: Black/Black/Digital, Color: Black/Black/Digital
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.
