A. Lange and Söhne 116.032 (Pre-owned - Excellent) — USD 35,990 on eBay

The A. Lange & Söhne Lange 1 Time Zone reference 116.032 is one of the most brilliantly conceived travel watches in all of horology. Housed in a 41.9mm 18kt rose gold case with a silver dial, this timepiece presents two complete time zones on its face, each with its own hour and minute hands and its own separate day/night indicator. A city ring around the dial periphery allows the wearer to identify the second time zone at a glance, while the outsize date and power reserve indicator maintain the Lange 1 family's functional identity. The caliber L031.1, developed specifically for the Time Zone complication, stores 72 hours of power reserve and incorporates an ingenious mechanism that allows the home time and local time to be set independently in one-hour increments. The movement is wound manually, maintaining the direct, tactile connection between owner and timepiece that A. Lange & Söhne considers essential. Through the sapphire caseback, the L031.1 reveals the same obsessive hand-finishing found throughout the Lange lineup: the proprietary Glashuette ribbing on the three-quarter plate, the hand-engraved balance cock, and blued screws precisely heat-treated to achieve their distinctive cornflower hue. Reference 116.032 in rose gold with silver dial offers a refined, approachable aesthetic for a watch of considerable mechanical complexity. The silver dial ensures excellent legibility despite the density of information displayed, and the rose gold case adds warmth without excess. For the global traveler who refuses to compromise on mechanical excellence, who wants to know the time at home and abroad without reaching for a phone, the Lange 1 Time Zone stands as a triumph of intelligent design from the Glashuette manufacture.
