Automatic chronographs can keep time and be used セイコー腕時計 as a stopwatch without manual winding. A chronograph is a watch that is capable of keeping time, as well as act as recording discrete elapsed time like a stopwatch. The movements ドルチェ＆エクセリーヌ are the compilation of minute actions inside the watch that allow it to accurately keep time. Manual-wind chronographs were the standard until 1969, when automatic-winding chronographs were introduced.

However, this watch, called "El Primero," wasn't available to the public until October 1969, by which point two other watch manufacturers had already released competing versions.

Many high-end watch manufacturers design their own movements for their watches, but there is one that is more well-known and widely implemented than others.
