Artem Sizing Guide: HydroFlex Sailcloth Strap

Find Your Perfect Fit

You'll need at least one measurement to choose an Artem Hydroflex strap that fits perfectly: the width (18mm, 19mm, 20mm, etc.). If you plan to swap the buckle for a different buckle or deployant clasp, you'll also need the strap/buckle taper. This Hydroflex watch strap sizing guide will help you measure watch strap size accurately and ensure a comfortable, secure fit.

Strap Width

On a wristwatch, lug width determines strap size. "Lug width" refers to the distance between the two projections that hold your strap in place, as shown.

Measure your lug width using a metric ruler or a caliper. The width must be in millimeters (not inches), and it must be a whole number (18mm, 19mm, 20mm, etc.). The strap size will match the lug width. If your lug width is 20mm, select a 20mm strap.

Strap Length

Artem's Hydroflex straps are available in one length. To make sure that this length works for you, you'll need your wrist measurement in inches.

Using a flexible tape measure or a strip of paper, wrap your wrist where your watch would naturally sit. Mark the point where the two ends meet.

If using a paper strip, use a ruler to measure it (in inches). That number is your wrist size.

Note: The HydroFlex strap can fit wrists larger than 7½ inches, but you may be wearing it on the second-to-last or last hole.

Strap/Buckle Taper

The strap/buckle taper is important information if you're swapping out the buckle. Artem's straps taper in width toward the buckle as shown below.

Artem straps taper toward the buckle; confirm the correct width before replacing it.

Your buckle width matches the width at the buckle end of the strap, not the lug end.

Example: Artem's 20mm strap tapers to 18mm at the buckle. For this strap, you would select an 18mm deployant clasp or buckle. A 20mm clasp will be too big.
