As an aid to the disoriented world traveler, the back of the watch is conveniently engraved with a chart showing the offset from Greenwich Mean Time/UTC, of 24 reference cities (although given the still-widespread use of the absurdity that is DST, one is still advised to check local time in that magical interval when you are putting your seat fully upright and stowing your hand luggage for landing). The bracelet and buckle of the Hydrocarbon AeroGMT II, by the way, are superb: very strongly built, with brushed outer and polished inner links, screw fittings rather than the cheaper friction-fit collar-and-pin links seen in many less expensive bracelets, and four—count 'em four—screws holding the solid end-links in place at the lugs. This is not a watch that intends to allow itself to be lost thanks to the failure of a two-dollar spring bar. The double folding clasp closes and locks with considerable authority, and the stolidity of the view once it's shut is nicely broken up by the rather baroque Ball double-R logo.
