Most people look best with a round case, and a watch sized between 40-44mm wide looks good on the wrists of 95% of men.

It is often safe to go with a well-known brand with a lot of history, the longer a brand has been making watches the better the results in many instances.

Some watches are more branding than substance, watch out for brands with bloated prices thanks to merely adding precious metals and jewels to base watches and movements that aren't worth very much.

People tend to doubt their own taste and try to buy what they think people want them to wear, people should realize that their own taste is the most important and that legibility and wearing comfort are the two most important factors in allowing them to enjoy it the longest.

Highly complicated mechanical watches add value but also fragility and potential service problems, those with very complicated timepieces are advised to have a few of them so that they have something else to wear if they need to be repaired.
