relojcronógrafo

A relojcronógrafo is a type of watch that includes a stopwatch function in addition to its timekeeping capabilities. The word "relojcronógrafo" itself is a portmanteau of "reloj" (Spanish for watch) and "cronógrafo" (Spanish for chronograph). This function allows the wearer to measure elapsed time independently of the main time display.

The stopwatch mechanism in a relojcronógrafo is typically operated by pushers located on the side of the watch case. One pusher usually starts and stops the chronograph, while another resets the hand(s) to zero. The chronograph display often consists of sub-dials on the main watch face that indicate minutes and seconds, and sometimes hours, of elapsed time. The main timekeeping aspect of the watch continues to function normally while the chronograph is in use.

Relojcronógrafos are popular among watch enthusiasts and collectors due to their mechanical complexity and practical utility. They find applications in various fields, from motorsports and aviation to everyday use where precise timing is desired. The intricate inner workings of a chronograph movement, involving numerous gears, levers, and springs, are often a testament to watchmaking craftsmanship. Early chronographs emerged in the 19th century, evolving significantly over time in terms of accuracy, functionality, and design.
