When you buy a new watch online, you'll want to make sure it fits your wrist well.
If it's too small or too large, it may look terribly large or be super uncomfortable! Pro-tip: Don't be an idiot like me and buy a 45mm Omega Planet Ocean for $5k for my 6.5" wrist, only to realize it's the most uncomfortable watch I've ever worn!
You can't try it on when you shop online, and you don't want to have to return it just because you ordered the wrong size..
