Lug Measurement Tool

A card tool that tells you the lug width of your watch.

What it is

One card. 14 lug widths.

The Delugs Lug Measurement Tool is a slim, credit card-sized card with precision cutouts along each edge. Each notch corresponds to a lug width – from 12mm to 26mm – so you can easily confirm your lug width at home or on the go.

How to Use It

1. Remove your current strap or bracelet

Take the strap or bracelet off your watch so the lugs are fully exposed.

2. Slot the tool between the lugs

Hold the tool against the bottom of your watch case and slide the card's notches between the lugs. Start from a smaller size and work upward. The correct size is the notch that fits snugly without forcing.

3. Read the number

The number printed under the fitting notch is your lug width in millimetres. Use that exact number when browsing straps at Delugs.

Know your lug width. Shop with confidence.

Now that you have your lug width, finding the perfect strap is the easy part.

FAQs

What if my watch falls between two widths?

In the rare instance where your watch lugs fall between two widths (e.g., 17.8, 22.5), feel free to contact our Customer Support Team with your watch model/reference number, and pictures if you can, via the Live Chat or support@delugs.com.
Do I measure at the top (12 o'clock) or bottom (6 o'clock) of the case?

If your lug arms are designed to be the same, there's no difference!
Can I use this with a bracelet still attached?

Only if your bracelet has a space large enough at the lugs to accommodate the tool. This tool is meant to fit between the lugs, and most bracelets will not offer sufficient space.
