Garmin Forerunner 255 — band questions
What size strap does the Forerunner 255 take?
The Garmin Forerunner 255 has a 22mm lug width, so you need a 22mm watch strap.
Will any 22mm strap fit the Forerunner 255?
Most will. Width is the main thing to match, but also check that the strap's spring-bar holes suit the bars, and that the strap is thin enough to clear the case between the lugs. A metal bracelet needs 22mm end-links made for this model.
What spring bar size does the Forerunner 255 use?
22mm long. We haven't confirmed the diameter for the Forerunner 255, so measure the original bar with calipers before buying replacements.
Is the Forerunner 255 good for strap swapping?
Yes. With standard 22mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
