Match the occasion
First and foremost, a watch should match an occasion’s tone.
As a rule, analogue watches are more formal while digital and Apple watches more casual.
You wouldn’t wear a T-shirt to a wedding and you shouldn’t wear a cheap digital watch either.
Next, ask yourself just how formal is your event?
Different suits and watches are tailored for different degrees of formality. As a rule of thumb, the more formal the event, the simpler the design should be, albeit with gold or silver faces.
Match your watch to your outfit
Ideally, your watch should complement your ensemble with your belt being a natural point of comparison.
Wearing a noticeable leather belt?
Go with a noticeable leather band for your watch.
Wearing fine silver cuff links?
Complement them with an elegant silver-banded wristwatch.
Finally, black suits are easiest to match.
Don’t hide your watch
It’s no good if your beautiful watch is hiding behind a long suit or sleeve.
Your suit should be short enough to show off your watch, but not so short that it exposes your wrists.
Ideally, a well-fitted suit , should sit just above where your hand and wrist meet.
This means that when you make certain movements with your arm, the jacket will naturally roll back to expose your watch.
