I got one last year, and it works very well. It is very accurate, only gaining about a second per week. I told the story of how I decided to buy it in this thread that asked whether advertisements have an effect on what you purchase. This is what I wrote:
One notable example for me was when I needed a watch. As I was looking in the display cases at the department store, I saw these little photo displays of Kesha wearing Baby G watches. (She even designed a couple of them herself.) I thought that was so cool, but still I decided to buy another brand of watch (Skagen). However, the band on the Skagen broke after only 99 days.
I decided I wouldn’t make the same mistake twice. I exchanged the broken Skagen for a G Shock (made by the same manufacturer as Baby G). The saleslady kept trying to get me to take another Skagen. “It’s a better watch than the G Shock…I’ve had my Skagen for over 20 years…I guarantee you the replacement won’t break.” Finally I got her to shut up and give me the G Shock. I’ve now had my G Shock for well over 100 days, and it hasn’t given me any problems whatsoever.
Proof that Kesha knows more about watches than the watch saleslady does.
