📏 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

⌚ 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

🕵️ 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.
