World Time is a sophisticated watch feature that displays multiple time zones simultaneously. It's a valuable complication in luxury watches that shows the local time along with the time in major cities around the world, typically displayed on the outer ring of the watch face. When looking at resumes in watchmaking, this term indicates experience with complex watch mechanisms. Similar terms include "GMT" (which shows two time zones) or "Universal Time" watches. Understanding World Time mechanisms is particularly important for watchmakers working with high-end brands like Patek Philippe, Vacheron Constantin, or Jaeger-LeCoultre.
