I bought four pieces of this button compass and am very satisfied. All reliably fulfill its purpose, ie, all facing north and have been completely sealed. Addendum: I do not use the compasses on a watch band but at different backpack straps and tabs. Sometimes you have the button compass tilt slightly so that it can freely rotate and align. Otherwise, I can do it as a small "always there" in the backpack still recommend -Compass example. Of course he is not a substitute for a high-quality map or mirror compass is - but this he is probably not intended.
