Bit of a curve ball, but I'm a huge fan of a simple casio.
When you're in a city or a deprived poorer area, it's far safer to look at your watch than take out your phone.
It's also more professional in a work context, especially in customer facing roles. If you look at your phone to check the time, people are more likely to think you're checking your notifications and not fully engaged in what you're doing.
