The G10LM is a current G10 / General Service pattern field watch and is a slightly smaller and more compact version of the MWC G10 50m battery hatch variant. Although this watch is similar in appearance to some other manufacturer's models it is significantly different in the specification details. For example, where other manufacturers watches usually use a push on caseback this watch has a screw-down caseback which improves water resistance, competitors also frequently use perspex/plexiglass crystals whereas MWC utilize actual glass which makes the watch both more scratch resistant and also significantly more streamlined in appearance.
