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.
