⌚ Watch Strap Size Guide for Vintage & Luxury Watches

Choosing the right watch strap comes down to two measurements: your lug width and your wrist circumference. Get those right and any strap will fit perfectly. This guide covers everything you need — from measuring your watch to selecting the correct strap length, spring bar size, and material for your vintage or luxury timepiece.

📏 Lug Width

The lug width is the inner gap between the two lugs on your watch case — the space where the strap end fits and the spring bar sits. It is always measured in millimeters and is the single most important number when ordering any strap or bracelet.

• Men’s watches: typically 18mm to 22mm
• Women’s watches: typically 14mm to 18mm

⌚ Vintage Watch Strap Sizing

Historically, many vintage Swiss watches followed an informal rule: the strap width was approximately half the case diameter. While not universal, it remains a useful starting point for vintage pieces.

📊 Lug Width by Brand

Use this table as a quick reference. Always confirm by measuring your specific reference, as lug widths can vary by production year and model variant.

*Omega 34mm – 35mm models technically use 17mm or 17.5mm, but an 18mm strap fits in most cases as the 0.5mm difference is minimal.

📏 Wrist Size & Strap Length

Wrap a flexible tape measure or strip of paper around your wrist just below the wrist bone — where you normally wear a watch. Note the measurement in millimeters. Most straps are listed as two numbers (e.g. 75mm / 120mm) — the short end sits on the inside of your wrist, the long end wraps around and passes through the buckle.

🧷 Spring Bars

Spring bars are the small cylindrical pins that secure the strap to the watch lugs. The spring bar diameter must match the lug hole, and the spring bar length must match the lug width. Always use the correct size — an undersized spring bar can fail and cause the watch to fall from the wrist.
