I get the fun part of engineering this but can't put aside that it doesn't bring that much new feature, a thermometer, international time, more advanced chronometer. That's all thing that I don't really care about.

On the downside, you loose the cheap aspect of this watch and the battery life is divided by 7. From 7 years to supposedly a full year.

I buy a f91w because it cost less than 5€ and I don't care to break it or get it stolen.
