If you’re jet setting type, bombing the Alps one day and escaping Alcatraz the next, timekeeping can become an especially taxing chore while traversing across time zones. Designed specifically for these situations, IWC has created the Portofino Dual Time ($17,600). The timepiece features an all-new 64710 calibre movement with 72-hour power reserve, double-sided AR coated sapphire glass and a separate 24 hour subdial for keeping track of time back home. The mechanical movement will even adjust the date forward or back as you set the time — allowing for adjustment in one-hour increments. Measuring in at a substantial 45mm, the Dual Time should prove to be easy on your eyes after a 12 hour red-eye too. When it arrives this fall it will be available in red gold with a black dial (pictured) or stainless steel with either a black or silver dial and complete with alligator leather straps by Santoni.
