Zenith’s El Primero Rainbow Flyback deserves a modern revival—not merely another colorful watch, but a return of the late-1990s chronograph conceived for semiprofessional pilots and notable for bringing flyback to the El Primero line. Zenith has not announced a reissue; this is an argument for one.
Why the original Rainbow Flyback mattered
Zenith’s official timeline dates the Rainbow Flyback’s debut to 1997 and describes its intended audience as semiprofessional pilots. The brand’s concise account is: “Designed for semiprofessional pilots, it introduces a new function for the El Primero: the flyback.” That makes the watch more than a bright variation on a chronograph: it joined a practical pilot-oriented brief to a meaningful addition to the El Primero family.
Flyback lets a wearer reset and restart a running chronograph in one action, rather than stopping it, resetting it, and starting it again in separate steps. That function suits timing successive intervals, which helps explain why it belongs in a pilot-oriented chronograph. Zenith’s timeline identifies it as a new function for the El Primero, not as the invention of flyback itself. Zenith’s official illustrated timeline is the source for the model’s debut, purpose, and place in the line.
The El Primero connection is the real reason to revive it
Zenith dates the El Primero’s unveiling to January 10, 1969. Its timeline calls it the world’s first automatic chronograph; that superlative is the manufacturer’s historical claim. Zenith also describes the integrated, automatic movement as running at 36,000 vibrations per hour, a high frequency that enables measurement to one-tenth of a second.

A Rainbow Flyback revival could make that lineage tangible again: high-frequency chronograph timing paired with a flyback function and an identity grounded in aviation. The point would not be to copy an old dial or capitalize on the word “rainbow.” It would be to bring back the combination that made this particular El Primero distinctive.
What a revival should bring back—and what it need not copy
Zenith has not announced a Rainbow Flyback reissue, so any specification for a future model would be a proposal, not a description of a product on sale. A persuasive revival would preserve the qualities established by the original history while giving the watch a considered contemporary execution.
Rank #2
- Keep the pilot-chronograph purpose. The 1997 model was designed for semiprofessional pilots. A revival should make that functional identity central rather than treating the watch as only a colorway.
- Retain flyback. It was the function Zenith specifically identifies as new to the El Primero with the Rainbow Flyback. Leaving it out would weaken the case for reviving this model rather than simply releasing another El Primero chronograph.
- Respect the El Primero’s high-frequency character. Zenith links the original line’s 36,000 vibrations per hour to measurement in tenths of a second. A new watch should explain clearly how its movement and display serve that legacy.
- Use color with purpose. The rainbow identity should remain recognizable, but a pilot-led design need not imitate every vintage detail or turn the watch into a gemstone-set luxury statement.
- Make it a distinct watch, not a renamed substitute. The Rainbow Flyback’s aviation-oriented history gives it an identity separate from the current Chronomaster Sport Rainbow.
The Chronomaster Sport Rainbow is not the old Rainbow Flyback returned
Zenith’s January 21, 2025 announcement introduced a rainbow version of the Chronomaster Sport. It is a separate watch, and the announcement does not describe it as a revival of the 1997 Rainbow Flyback.
| Point of comparison | El Primero Rainbow Flyback | Chronomaster Sport Rainbow (2025) |
|---|---|---|
| Identity | Debuted in 1997; Zenith says it was designed for semiprofessional pilots and introduced flyback to the El Primero. | A rainbow version of the Chronomaster Sport, presented by Zenith as a more luxurious model. |
| Case and materials | For reference 02.0480.405/24 only, The 1916 Company’s 2026 review result reports a 39mm stainless-steel case. This secondary listing detail should not be generalized to every variant. | Zenith specifies a 41mm 18k white-gold case and a bezel set with 50 baguette-cut gemstones. |
| Movement and timing | Zenith’s timeline identifies flyback as the new function for the El Primero; the cited timeline does not give a reference-specific movement specification. | Zenith specifies the El Primero 3600 at 5 Hz/36,000 vph, a chronograph seconds hand that makes one full dial rotation in 10 seconds to display tenths, and a 60-hour power reserve. The announcement does not establish whether this model has or lacks flyback. |
| Availability | Discussed here as a pre-owned collectible; no current stock or price is established by the cited sources. | Zenith’s 2025 release says it was available through the brand’s physical and online boutiques worldwide. |
The modern Chronomaster Sport Rainbow shows that Zenith has recently used the rainbow idea in a different design language. Its 2025 release is not evidence that the older pilot-oriented model has returned. Read Zenith’s Chronomaster Sport Rainbow announcement for the modern watch’s published details.

One documented vintage reference—and how to approach it
A 2026 review result from The 1916 Company identifies the El Primero Rainbow Flyback reference 02.0480.405/24. For that reference, the dealer reports a 39mm stainless-steel case, black dial, central chronograph hand, 30-minute and 12-hour counters, date, small seconds, 12.6mm thickness, and 46.4mm lug-to-lug. These are secondary listing details tied to one reference, not a complete Zenith specification for every Rainbow Flyback. The review result is available at The 1916 Company’s reference-specific review.
If you are considering a pre-owned example, verify the watch in front of you rather than relying on a model name or a listing photograph. Zenith lists maintenance and restoration among its services, but the availability or suitability of service for a particular vintage watch needs to be confirmed directly.
Rank #4
- Confirm the exact reference and that the case, dial, hands, bezel, and movement correspond to the watch being offered.
- Ask for service documentation and the date and scope of the most recent work.
- Have a qualified watchmaker assess chronograph operation, including the flyback action, and inspect the watch’s condition.
- Ask Zenith or a qualified watchmaker about service options for that specific watch before buying.
The cited information does not establish vintage service prices, turnaround times, parts availability, or market values. Those can depend on the individual watch and should be checked with the service provider or seller rather than assumed from a reference number.
