Why We Love it
–Zenith, while not a household name, is certainly a known name in the world of watches - particularly in collecting circles. The primary reason?
The El Primero.
In icon of this caliber tends to have some side effects for its name brand - in this case - other models from the era in Zeniths line up perhaps not getting the recognition that the deserve - leaving plenty of forgotten gems in the brands past.
One such example is this Reference A3634 world timer. This incredibly cool piece features a lovely sunburst blue dial with tritium indices and matching handset, a sporty 37mm case, and a bidirectionally rotating world-time bezel.
The A3634 may not be an icon - yet - but it absolutely sums up what we love about vintage, particularly lesser-known vintage timepieces that we have become known for.
Don't miss it!
Brand Story

Brand Story
+Zenith's chronographs in particular gained a reputation for excellence. At first Zenith used Excelsior Park and Valjoux movements, sharing them with Universal Genève and Movado (with which Zenith would merge for a time in 1969). By the 1960s Zenith acquired ébauche manufacturer Martel and began using their movements exclusively, leading to lauded calibers such as the 146HP and 146DP, which launched in 1969.
1969 was a banner year for horology, as it saw the launch of the first automatic chronograph movement. This was a race between a team consisting of Hamilton, Heuer, Buren, Dubois-Depraz, and Breitling; Seiko; and Zenith. Zenith used the Caliber 146 as a basis for the caliber which the brand would dub "El Primero" — "the first." Of the consortium’s Caliber 11, Seiko’s reference 6139, and the El Primero, only the latter feature a “high-beat” movement for increased accuracy.
Zenith ceased using manually-wound movements in their chronographs after the introduction of the El Primero — however, then the Quartz Crisis of the 1970s hit, and the company was sold. Employees were ordered to destroy or otherwise liquidate their mechanical watchmaking tooling, but incredibly, one daring engineer, Charles Vermot, decided to hide machinery behind a false wall that he built himself in the attic of the company’s manufacture in Le Locle. He told no one about what he was doing — not even his family.
Then, in the 1980s after the company had changed hands once again, he led modern Zenith management to this secret cache of horological wonders, in which the El Primero tooling was hidden. Ebel placed the first modern order for El Primero movements in 1984, but it was Rolex, who ordered thousands of calibers to power their new automatic Daytonas, that saved the firm. Today, the El Primero powers numerous vintage-inspired chronographs as well as the new Chronomaster Sport, a watch aimed as a competitor at — with much irony — the Daytona.
