Timex Expedition Scout 40 — strap questions
What size strap does the Expedition Scout 40 take?
The Timex Expedition Scout 40 has a 20mm lug width, so you need a 20mm watch strap.
Will any 20mm strap fit the Expedition Scout 40?
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 20mm end-links made for this model.
What spring bar size does the Expedition Scout 40 use?
20mm long. We haven't confirmed the diameter for the Expedition Scout 40, so measure the original bar with calipers before buying replacements.
Is the Expedition Scout 40 good for strap swapping?
Yes. With standard 20mm spring-bar lugs, NATO, leather, rubber and mesh straps can all be fitted with a spring-bar tool.
