Relojcronógrafos

Relojcronógrafos, often referred to as chronographs, are timepieces with a built-in stopwatch function. This distinct feature allows the wearer to measure elapsed time independently of the main timekeeping function. Typically, chronographs are operated by a series of pushers located on the side of the watch case. The upper pusher usually starts and stops the stopwatch mechanism, while the lower pusher resets the hands to zero.

The stopwatch function is usually displayed by one or more sub-dials on the main watch face, often measuring seconds, minutes, and sometimes hours. These sub-dials are distinct from the main hour and minute hands. The central chronograph seconds hand is the most prominent feature of a chronograph, sweeping across the dial when activated.

The development of the chronograph dates back to the early 19th century, with early versions designed for astronomical and scientific purposes. Over time, they evolved into popular tools for pilots, race car drivers, and military personnel, valued for their precision and utility in timing events. Today, chronographs are a popular complication in mechanical watches, appreciated for their technical complexity and aesthetic appeal. Modern chronographs can range from simple two-pusher designs to more complex variations with flyback or split-seconds functions.
