📏 Lug Width
The lug width is the distance between the lugs (metal extensions on the watch case) where the strap is attached. This is measured in millimeters (mm) using a ruler or caliper.
Common lug widths:
- Men's watches: 18mm to 24mm
- Women's watches: 14mm to 18mm

⌚ Vintage Watch Strap Sizing
Historically, many vintage watches followed an informal rule where the strap width was half the case diameter. For example, a 36mm watch often used an 18mm strap. While not universal today, it still applies to many models:
- 36mm watch → 18mm strap
- 40mm watch → 20mm strap
Common vintage watch lug sizes:
- Vintage Breitling Navitimer: 22mm
- Rolex 36mm: 19mm
🕵️ Omega Watch Strap Sizes
Omega watches are known for having a wide variety of case sizes and lug widths:
- 34mm Omega: 17mm strap
- 35mm Omega: 17.5mm strap
- Most people use an 18mm strap instead of 17.5mm, as the 0.5mm difference is often unnoticeable
🧵 How to Measure Your Wrist Size
Use a soft tape measure or a string to wrap around your wrist. Then measure that string against a ruler to get your wrist circumference. This will help determine the appropriate strap length.
📐 Strap Length Guide
Watch straps come in standard lengths:
- Short: Small wrists
- Regular: Average wrist size
- Long: Larger wrists
Ensure the strap allows for enough room without being overly tight or loose.
🔩 Watch Strap Types & Fit Considerations
Straps are made from various materials, each with its own fit characteristics:
- Leather: May stretch slightly over time
- Metal bracelets: Adjustable links for precise sizing
- Nylon/Rubber: More flexible and often universal
🧷 Spring Bars
Make sure to use the correct size spring bars to match the lug width. These small bars secure the strap to the case and ensure a safe fit.
