My husband bought this watch for work. He can’t have his phone on him at work so this watch has been very useful for him. He sweats a lot and works in a warehouse. He has a nicer “church” watch I bought him as a wedding gift and he actually has started to prefer this one. There are only two little annoyances (which might be able to be fixed) every hour the clock beeps and that the alarm goes off every morning including weekends. Those things might be features which some desire and some that even we are impressed by so 🤷🏻‍♀️ as I said, those minor issues might be fixed if we look into them but my husband doesn’t find them as bothersome as I do and he’s the one who wears it.
