Ever since the dawn of time, man has studied "time". From using obelisks to waterclocks and eventually wristwatches in modern era. It's easily understood that time was important back then and it's still vital now. I don't just mean knowing how to read the time, most people can do that. But not many people keep track of the time. For these people, time drifts by day after day, and before you they know it, weeks has passed without them realising. If this applies to you, then perhaps a watch will help you to construct and organise your time a bit better.
"But I have a phone that tells the time already, why do I need a watch?" That's a common question with a simple answer. You don't have to pull your watch out every time you want to know the time! (unless you always have your hand in your pocket). Using your phone to check the time is a hassle and often inconvenient, especially during work and on night outs.
Stopping to ask random strangers for the time isn't much better either. If you're lucky, you won't get ignored by a busy passer-by or you won't get the reply "Sorry, I don't know". I can assure you that someone will be thinking why you don't just buy a watch. You've probably have had that thought cross your mind also and after a while, it'll make sense!
There's plenty different watches and one that will definitely suit your character and look. But If you're reluctant to dish out a lot of money on a watch, not to worry as there are also a tonne of inexpensive watches that are reliable and have excellent designs. They may not be blinged up with diamonds and gold, but for now, you're trying to keep track of time, you're not flaunting on television. You don't have to be a watch enthusiast to take an interest, although it does help!
If the basics of timekeeping just isn't a good enough reason for you, then perhaps the wide range of functions that many watches have to offer will persuade you. What about a Chronograph stopwatch? Moonphase? Perpetual Calender? World Timer? I'm sure you can find use of one of those aspects of a watch. As soon as you do decide to take action and purchase a watch, check out the reaction of your peers and how much more efficient you are in your daily activities, then you'll realise what you've been missing out on.
Combining this perspective with one of a more urgen one; the job market of today is increasingly competitive and some people have been left feeling down and out. When you've got that big job interview this next week to think about a wrist watch is probably one of the last things that you've got on your mind but it should still be something to think about.
A good, solid resume aside; most employers make their decision within the first few minutes of the interview and you should have every advantage in place for this time frame such as having relevant information already in mind, talking points on the resume or other documentation you'd bring in, appropiate attire and a fine timepiece to augment your persona.
If you've got the credentials in hand of your abilities and have a vivid and confident appearance to back it up you'll have that much more chance to land that job! Good luck out there!
