Lug Width Fitting and Strap Sizing Guide

1. The right fit for your watch

Our lug width measurements are typically labelled with two main measurement number metrics e.g. '20-16'. The first number (a) represents the strap's lug width measurement, to match with the lug width measurement of the watch case (b), while the second number (c) represents the strap's buckle width measurement.

To determine the lug width measurement of your watch, simply retrieve them from the product's specification information (commonly found on the respective brand's website), or measure by hand using a ruler or caliper from one lug end to the other (c).

* Do note that watches that requires a curved spring bar are typically designed for watches with lug holes drilled closer to the watch's case. We do not recommend fitting a standard straight spring bar to fit a watch designed to be fitted with a curved leather strap as it may possibly damage the spring bar and leather strap itself.

2. The right fit for your wrist

There are certainly a few methods to go about getting the right strap size to fit your wrist. However, nothing beats a quick and accurate measurement of your wrist size to ensure the perfect fit (you'll also thank yourself for future strap purchases!)

Determine your wrist size

• Wrap a measuring tape around your wrist just below the wrist bone or slightly under, depending on your watch wearing preference.
• If you do not have a measuring tape, you can also use a string or a strip of paper and mark the point where it overlaps.
• Measure the length of the string or paper strip with a ruler or a measuring tape to determine your wrist circumference.

Determine your preferred fit

• Consider the type of fit you prefer for your watch wearing experience. Slightly snug, or slightly loose, you decide!
• Keep in mind that the ideal fit should be comfortable to wear throughout long hours, with decent space allowance for some movement on your wrist.

Calculate the ideal strap length:

(e) represent the long tail end length while (d) represents the short buckle end length (e.g. 105-65mm means that the length of the long tail end length is at 105mm while the short buckle eng length is at 65mm.

• If you prefer a snug fit, subtract about 2-4mm (0.08-0.16 inches) from your wrist circumference to account for the strap's thickness.
• If you prefer a looser fit, add about 8-10mm (0.3-0.4 inches) from your wrist circumference.
• Just note that a little "tail" at the end of the strap can be exposed if the strap length chosen is slightly longer.

Pro-Tip #1: Found your wrist size in the middle of two strap length sizes? Our recommendation is to always size up. This gives you ample allowance to wear the strap without the risk of it being too tight/snug.

Pro-Tip #2: If you already have a strap that you are comfortable with in its length and fit, simply give it a quite measurement of both ends of the straps and you're good to go!
