What case size should I choose?
The watch case is the part of the watch that holds the dial, the battery, the clockwork and other working parts. The diameter (width) of the watch case is the most significant and noticeable measure when it comes to choosing the right watch. So it is good to buy a watch with the size that suits you.
Generally, the following applies to case width sizes:
