El Primero Rainbow Flyback

The Zenith El Primero Rainbow Flyback draws its name and inspiration from the colorful dashboard instruments of 1990s French military helicopters, for whom it was originally designed. As part of Zenith’s celebrated El Primero line, this chronograph stands out for its aviation roots and its rare, purpose-built flyback function—a feature prized by collectors who value both technical pedigree and authentic tool watch heritage.

Key references include the 02.0480.405 (stainless steel) and 18.0480.405 (yellow gold), both powered by the automatic El Primero 405 caliber with flyback capability. The 40mm case, water resistance to 100m, and colorful dial accents make it a practical and visually striking choice. Steel versions typically command more attention due to their direct military lineage, while gold variants appeal to those seeking rarity and luxury.

Pricing varies based on condition, completeness (box and papers add value), and the originality of the unique multi-colored hands and bezel. Early tritium-dial examples and unpolished cases are especially desirable. When shopping, check that the flyback function operates crisply—service history matters, as the 405 movement is sophisticated and benefits from expert maintenance.
