Split-seconds (also known as a rattrapante) is a special feature in high-end watches that allows measuring two separate time intervals at once. Think of it like having two stopwatches in one watch. This is particularly useful when timing two competitors in a race or measuring multiple events happening simultaneously. It's considered one of the most complex and prestigious features in watchmaking, showing a watchmaker's advanced skills. When you see this term in a resume, it indicates experience with sophisticated watch mechanisms.
