"But I already have a phone that says the time, why do I need a clock?" It is a common question with a simple answer. You do not have to take your watch every time you want to know the time! (Unless you always have your hand in your pocket). Using the phone to check the time is a nuisance and often inconvenient, especially during work and night outings.
To stop asking random strangers at the moment is also not much better. If you are lucky you will not be ignored by a busy passport or you will not receive the answer "Sorry, I do not know". I can assure you that someone will think why you do not buy a watch. It is likely that you also had the mindset in your mind, and after a while it would be sensible!
There are many different watches and one that certainly fits your character and appearance. But if you resist spending a lot of money on a watch, do not worry, as there are also a ton of cheap watches that are reliable and have excellent design. They can not be full of diamonds and gold, but at the moment you try to keep an eye on time, you are not flaunting tv. You do not have to be an urine enthusiast to be interested, even if it helps!
If the basics of timing are not a good reason for you, then it may be the wide range of features that many watches have to offer will persuade you. What about a chronographic chronicle? Moon phase? Eternal Calendar? World hours? I'm sure you can find one of these aspects of a watch. As soon as you decide to shop and buy a watch, check your peers' reaction and how much more effective it is in your daily activities, and you will realize what you have missed.
