History and Significance
The El Primero is one of the most important automatic chronograph movements ever made, introduced in 1969 and still in use today in evolved form. It was one of the first high-beat automatic chronographs, running at 36,000 vibrations per hour, which allows for greater precision and a smoother sweep of the chronograph hand.
The Chronomaster line takes that technical foundation and presents it in a more classical format. References like the 01.0240.410 lean into traditional watchmaking cues with a more detailed dial, calendar functions, and a case design that feels closer to mid-century chronographs than modern sport pieces.
This particular configuration stands out because of the dial. The guilloché work adds depth across the entire surface, breaking up what could otherwise be a busy layout. Between the triple calendar, moonphase, and chronograph registers, there is a lot going on, but the dial manages to stay legible and balanced.
Writer's Thoughts
The guilloché dial El Primero is the one to own. A classic triple calendar moonphase with a chronograph brings serious value for those looking for complication movements. The complete set pair with the condition makes this one truly stand out. The El Primero is a movement everyone should own at least once, and this example is a great choice.
