4 rules to select the right watch size.
1. Our watches are generally large, even 42MM. However, due to the style of the watch you might consider a larger size than you usually wear.
2. The 45MM case watches are 12MM thic whereas 42MM case watches are 11MM thick.
3. The 45MM case watches have 20MM wide watch bands whereas 42MM case watches have 18MM wide watch bands.
4. Watches with a steel bracelet are heavier than with a leather watch band by 90 gram.
