Why Watch Size Matters
Proportionality
A watch that's too large overwhelms; too small looks lost. The right fit creates visual balance.
Comfort
Lug-to-lug determines how it sits. Lugs extending past your wrist dig in and feel awkward.
Confidence
Knowing your ideal range means fewer returns and more satisfaction with every purchase.
