Patek Philippe 5131G World Time "Email Cloisonné" Enamel Asia Europe Edition in 18kt White Gold Black DLC Bespoke Stealth Pure Black Physical Vapor Deposition. The dial is hand-painted enamel cloisonné depicting Europe, Asia, Africa and Australia, which only two artists at Patek Philippe are qualified to produce. There is a ring-shaped hour hand and dagger minute hand, with a night/day delineated 24-hour chapter ring. Around the perimeter are the 24 cities and time zones on a silver reserve.

It is fitted on an alligator leather strap with an 18K white gold deployment Patek Philippe emblem release buckle, and a scratch-resistant sapphire crystal with anti-glare coatings. There is a screw-down protected winding crown, and a rectangular push button at 10 o’clock on the left-side case band that activates the 24-hour GMT chapter ring, switching from one time zone to another. Each time it is pressed, the hour hand advances one hour while the city ring and 24-hour ring rotate counter-clockwise by one hour - equivalent to one-time zone. Pressing the button 24 times will produce a trip around the world, with a return to the original departure time. The local time, indicated by the hour and minute hands, refers to the location on the city disk that lines up with 12 o’clock. There is a screw-down exhibition case back, and the 39.5mm diameter solid three-body case, curved lugs, and angled flat bezel engraved with "PATEK PHILIPPE – GENEVE," are polished/brushed.
