Size & Fit Guide

Finding the right fit makes all the difference in how a watch wears. This guide will help you understand sizing before you buy.

Understanding Case Size

Case diameter is measured in millimeters (mm) across the case, not including the crown. As a general reference:

• Under 36mm — smaller, classic proportions.
• 36–40mm — versatile, mid-size; suits most wrists.
• 40–44mm — larger, contemporary presence.
• 44mm and above — bold, statement sizing.

Each product listing specifies the case size so you can judge how it will sit on your wrist.

Measuring Your Wrist

Wrap a flexible tape measure (or a strip of paper you can measure afterward) around your wrist where you'd wear the watch. As a rough guide:

• Up to ~16cm — smaller wrist; case sizes up to ~40mm often sit best.
• 16–18cm — medium wrist; most sizes wear well.
• 18cm and above — larger wrist; larger cases sit comfortably.

Bracelet & Strap Sizing

Metal bracelets can often be sized by adding or removing links; straps come in standard lengths. If a listing notes the current bracelet size or number of links, it will be shown in the description.
