These days I just use my phone. It's amazing how many times I used to look at my wrist watch. Now I think about pulling out my phone and I take a guess and I'm usually just a few minutes off. For decades I bought Casio digital watches and used the alarm in it to get up for work every morning. I would buy the watch and throw away the watch band and buy a Speidel watch band to replace it. Speidel makes a really good watch band.
