This is a fun question. Zenith is a great brand, but it has gone through so many design directions that it doesn’t have a predictable look. Essentially now they have the Chronomaster, which is aping the Daytona, and the Defy which is kind of aping the Royal Oak. Nobody wants to spend the MSRPs Zenith is asking for an hommage to what they really want.
Zenith needs a line that focuses on the heritage of the El Primero while adding some marketable technologies. For example, the Chronomaster Revival Shadow is a lovely piece, but in titanium with that finish and shape it will look beat to smithereens with any wrist time. Remake it in ceramic and market the robustness of the case. Include some hard erasers and inform the market on the ability to erase wear.
Do a similar campaign with the Rainbow Flyback. Use a ceramic in silver to mimic steel, but it’s unscratchable.
Update the El Primero and let everyone know. Let’s have silicon hairsprings, ceramic rotor bearings, increase the power reserve, and offer ltd edition hand decorated and regulated versions.
Zenith in the US was an insiders tip in the 90’s. Go for that vibe by marketing to watch enthusiasts.
