STRAPASTIC SIZE GUIDE

Since Strapastic straps come in a fixed size and can't be adjusted, it's important to find the right size. Every wrist is different, just like every watch, so we've put together this size guide to help you choose between Small (130mm), Medium (140mm), and Large (150mm) lengths.

STEP 1

DETERMINE YOUR WRIST SIZE

Using a tape measure, a piece of string, or a special measuring tool, wrap your wrist around the area where you usually place your watch, leaving as little margin as possible, then measure the result with a ruler. You now have your circumference!

STEP 2

MEASURING THE LENGTH OF YOUR WATCH

Next, determine the lug-to-lug length of your watch, using a ruler or ideally an electronic ruler, or even by consulting the manufacturer's technical specifications. Otherwise, a quick Google search will do the trick.

STEP 3

Subtract the length and add 10mm

Next, do a little subtraction: your wrist circumference minus your watch's lug-to-lug length. To this result, add 10mm to account for the distance between the lug holes and the end of the case. You now have your ideal size.

STEP 4

CHOOSE THE RIGHT LENGTH

Once you've determined your ideal size, all you have to do is choose the right Strapastic length. You have three options: Small (130mm), Medium (140mm), or Large (150mm). You'll likely be between sizes—or close to the larger size—and we recommend choosing a larger size.

FOR EXAMPLE :

Step 1 - Wrist diameter: 170mm

Step 2 - MoonSwatch lug to lug length: 47.3mm

Step 3 - Ideal size: 170mm - 47.3mm + 10mm = 132.7mm

Step 4 - Round up to the next size: 140mm or "Medium"
