Historical significance
Zenith Pilot 41 mm Skeletonised Quartz sits within Zenith's Pilot line, introduced in 1991. It carries the house codes established since 1865 — quartz tpt case, skeletonised dial and in-house automatic, chronometer certified — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
Zenith has spent more than 161 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's El Primero, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Georges Favre-Jacot established Zenith in 1865, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Zenith calibre produced today.
