Citizen Garrison — strap questions
What size strap does the Garrison take?
The Citizen Garrison has a 18mm lug width, so you need a 18mm watch strap.
Will any 18mm strap fit the Garrison?
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 Garrison use?
18mm long. We haven't confirmed the diameter for the Garrison, so measure the original bar with calipers before buying replacements.
Is the Garrison 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.
