Garmin Forerunner 265S — band questions
What size strap does the Forerunner 265S take?
The Garmin Forerunner 265S has a 18mm lug width, so you need a 18mm watch strap.
Will any 18mm strap fit the Forerunner 265S?
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 18mm end-links made for this model.
What spring bar size does the Forerunner 265S use?
18mm long. We haven't confirmed the diameter for the Forerunner 265S, so measure the original bar with calipers before buying replacements.
Is the Forerunner 265S good for strap swapping?
Yes. With standard 18mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
