Zenith El Primero Chronomaster ref. 02.0240.410, complete set from 2003

The Zenith El Primero Chronomaster ref. 02.0240.410 is an elegant timepiece that seamlessly blends Zenith’s legendary high-frequency chronograph movement with complete calendar and moonphase complications. Its 40mm stainless steel case and bracelet are perfectly constructed and feel very comfortable on the wrist. Powering this watch is the Zenith El Primero 410 movement, beating at an impressive 36,000 vibrations per hour — nearly twice as fast as a hand-wound Speedmaster Professional.

This watch is in excellent condition, exhibiting only minor signs of wear consistent with careful use and aging. The case and bracelet have light surface scratches, but no significant dents or scuffs. The dial remains pristine, with only a few very small specks of dust beneath the crystal. The bracelet is well-preserved, showing minimal signs of wear or stretching, while the clasp remains very secure and locks tightly without any looseness.

This watch comes complete with its original box, papers, and accessories. The sales receipt is dated to April 18, 2003.
