Frequently Asked Questions
How do I measure my wrist for a watch?
Wrap a flexible tape measure around your wrist just below the wrist bone (where you would normally wear a watch). Note the circumference in inches or centimeters. If using string, mark and measure with a ruler.
What watch size is right for my wrist?
For men: 6-7" wrist suits 38-42mm, 7-7.5" suits 40-44mm, 7.5"+ suits 42-46mm. For women: under 6" suits 26-34mm, 6-7" suits 28-38mm. The case should not overhang your wrist.
What is lug-to-lug distance and why does it matter?
Lug-to-lug is the distance from the top to bottom of the case including the lugs (where the strap attaches). This should not exceed your wrist width, or the watch will overhang. It is more important than case diameter for comfort.
How do I know my watch strap size?
Strap width is measured where the strap meets the case (lug width). Common sizes: 18mm, 20mm, 22mm, 24mm. Check your watch case or measure the gap between the lugs. Strap length depends on wrist circumference.
