Watch Strap Size Guide

Certainly! Watch strap sizes can vary, and it's important to know the correct size to ensure a proper fit for your watch. Here's a general guide on how to measure and choose the right watch strap size (Click here for Lug Width Sizing Tool - To Print and USE):

Lug Width: The lug width is the distance between the lugs (the metal parts that extend from the watch case) where the strap attaches to the watch. Use a ruler or caliper to measure this width in millimeters. Common lug widths range from 18mm to 24mm for men’s watches, and 14mm to 18mm for most women watches. This can vary depending on the watch model.

Vintage watches used to have an unwritten rule, which was half of the watch diameter. So, if you had a 36mm watch, the Lug size and your strap size would be 18mm. Clearly that is not the case for all watches, or a rule now. But still most 40mm watches use a 20mm lug size and watch strap size.

Given that EXPERTSWATCHES.COM deals with vintage watches, and most vintage watches use an 18mm to 20mm watch strap size. Most vintage Breitling Navitimers use 22mm lug size and watch strap size. Some 36mm Rolex used 19mm lug size and watch strap size.

Omega watches are different since they have a very big catalog of watches, in varying sizes and requirements. Where some 34mm watches used 17mm lug size and watch strap size. And 35mm watches used 17.50mm lug size and watch strap size. Most people can’t tell the 0.5mm width difference apart, and use a size up 18mm watch strap

Wrist Size: Consider your wrist size when choosing a strap length. Straps typically come in lengths suitable for different wrist circumferences. Measure your wrist with a tape measure or a piece of string, then measure the string against a ruler to determine your wrist size accurately. 

Strap Length: Watch straps often come in standard lengths: short, regular, and long. These lengths vary by manufacturer but are typically designed to accommodate different wrist sizes. Ensure that the chosen strap length will comfortably fit your wrist without being too loose or too tight. 

Strap Types: Watch straps come in various materials such as leather, metal, nylon, rubber, etc. Each material might have different flexibilities and sizing considerations. For example, leather straps might require a break-in period and can stretch slightly over time, while metal bracelets often come with adjustable links for size adjustments.

Spring Bars: Make sure to use the correct spring bar size that matches the lug width of your watch when attaching the strap securely to the watch case.

Remember, if you're unsure about the size, it's always a good idea to consult the watch manufacturer's specifications or visit a professional jeweler or watchmaker who can assist in determining the appropriate size for your watch strap. Additionally, many watch strap retailers provide size guides or offer assistance to ensure you get the right fit for your timepiece.
