Questions
What does a 18.5 mm lug width mean?
The gap between the two lugs of the case is 18.5 mm, so the strap must be 18.5 mm wide where it meets the case.
Which brands use 18.5 mm lugs most?
Tag Heuer (28), Festina (6), Longines (6), Edox (2), Breguet (1), among the references in our database.
Is the buckle width the same as the lug width?
Not always. Many straps taper toward the buckle, so a strap sold as 18.5-16.5 is 18.5 mm at the lugs and narrower at the buckle. Only the lug width has to match your watch.
How common is 18.5 mm?
It ranks number 38 of 42 lug widths in our database, with 0% of watch references with a listed width.

What is lug width?
The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.
Measure it in 30 seconds
- Take the strap off, or look at the back of it: many straps print their width.
- Measure the inside gap between the lugs with a caliper or a millimetre ruler.
- Round to the nearest whole millimetre. Most watches use 18, 20 or 22 mm.
Strap, quick release or system?
Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
