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.

It's a temperature compensated quartz watch, accurate to around 10 seconds per year. This puts it right up there with the highest end quartz watches. Even if you don't care about any extra features, it's worth it just for this.

It's also the only watch I've ever seen with a fully customizable and calibratable pulsometer. I know because I added that feature myself after shopping for watches and not finding a single one that had it. Use it every day at work too.

I agree with your points.

Where are you getting a genuine F91-W for 5€? A replacement 71604002 band costs me €8!

Walmart, they regularly go on clearance, no clue why.

I would also like to know this. I got mine for 12€ a while back and it looks to be going for around 20€ now.
