The right watch strap transforms both comfort and style. Yet many watch lovers struggle with sizing. Let's make it simple.
A perfect fit enhances your timepiece's appearance while ensuring all-day wearability. No more guesswork.
Understanding Watch Strap Measurements
Watch strap sizing follows a straightforward system once you know the basics.
The key measurements you need are:
- Lug width: Distance between watch lugs (where strap attaches)
- Strap length: Usually shown as two numbers (e.g., 115/75mm)
- Strap thickness: Material height
- Taper: How the strap narrows from lugs to buckle
Most premium straps like our Saffiano collection use a sizing convention where the first number represents lug width in millimeters. A "20mm strap" fits watches with 20mm between the lugs.
How to Measure Your Watch for the Perfect Strap
Finding your measurements is easier than you think.
Follow these simple steps:
- Measure lug width: Use a caliper or ruler to measure between watch lugs. Common sizes: 18mm, 19mm, 20mm, 21mm, and 22mm.
- Determine wrist size: Wrap measuring tape around your wrist where you wear your watch. This helps choose between short, medium, or long strap options.
- Check current strap: If replacing an existing strap, measure its width at lugs and buckle to understand taper (e.g., 20/16mm means 20mm at lugs, 16mm at buckle).
Precision matters—even 1mm off can result in poor fit or damage to your watch.
Common Watch Strap Sizes Explained
Standard sizes make shopping easier.
Popular watch strap widths include:
- 18mm: Perfect for dress watches and smaller timepieces
- 19mm: Common on mid-sized dress watches
- 20mm: Versatile size for many sports and casual watches
- 21mm: Found on larger sports watches and some dress pieces
- 22mm: Typical for larger dive watches and sports models,
Our straps taper to 16mm buckles, while our 22mm straps taper to 18mm for better balance and comfort.
Length Considerations: Short, Medium, or Long?
Strap length is just as crucial as width. We offer different options.
Standard length choices include:
- Short (105/70mm): Best for wrists under 6.5 inches (165mm)
- Medium (115/75mm): Ideal for average wrists between 6.5-7.5 inches (165-190mm)
- Long: For wrists over 7.5 inches (190mm+)
These measurements represent each strap half—the longer piece with holes (typically 115mm) and the shorter piece with the buckle (typically 75mm).
Special Considerations for Different Watch Types
Different watch styles have specific strap requirements.
For luxury sports watches:
- Rolex Submariner/GMT: Takes 20mm straps
- Omega Speedmaster: Uses 20mm straps
- Tudor Black Bay 58: Requires 20mm straps, very popular on our Slate Grey Suede
For dress watches:
- Cartier Tank: Needs 19mm or 20mm depending on model
- Patek Philippe Calatrava: Takes 18mm or 19mm straps
- JLC Reverso: May require custom sizing due to unique case shape
Always check your specific watch model's specifications before purchasing a new strap.
Choosing the Right Buckle Size
Buckle width should complement your strap's taper for balanced appearance. Our collections feature most straps tapering to 16mm buckles, while wider 22mm straps taper to 18mm for better proportion.
Common buckle sizes:
- 16mm: Standard for tapered straps
- 18mm: Used with wider straps or minimal taper
- 20mm: For straps with no taper
The right buckle size enhances both comfort and aesthetics.
