There is no single “best” 1960s Zenith: choose among the angular, water-resistant first-generation Defy; three early El Primero chronographs with distinct dial designs; and two manual-wind chronographs with very different proportions. The right watch depends on the shape and size you want, how much originality matters to you, and whether you prefer an automatic or hand-wound movement. This guide covers the six models selected by Jorg Weppelink in Fratello’s May 1, 2021 overview—not every Zenith made during the decade.
Compare the six watches at a glance
| Model | Case | Movement | Dial and defining character |
|---|---|---|---|
| Defy A364x | 37 mm octagonal case; 45 mm lug-to-lug | Automatic caliber 2552PC in the first-generation version | Multiple dial executions; date between 4 and 5 o’clock |
| El Primero A384 | 37 mm cushion-style case | Automatic caliber 3019 PHC | Silver-and-black panda dial, tachymeter ring, red central chronograph hand |
| El Primero A385 | 37 mm cushion-style case | Automatic caliber 3019 PHC | Smoky brown gradient dial with white chronograph registers |
| El Primero A386 | 38 mm case | Automatic caliber 3019 PHC | White dial with overlapping blue, light-gray and anthracite registers |
| A277 | 40 mm steel case; 14.5 mm thick | Manual-wind caliber 146H or 146HP, depending on version | Two-register chronograph; details vary between early and later versions |
| A. Cairelli CP-2 | 43 mm stainless-steel case | Manual-wind caliber 146DP | Black dial, two large registers and graduated rotating bezel |
Model and movement descriptions in this table follow Weppelink’s 2021 Fratello guide. The case dimensions are the figures reported there; they are not a substitute for trying a particular watch on, especially when comparing a vintage case’s shape and thickness.
Which 1960s Zenith fits your priorities?
First-generation Defy A364x: angular design, demanding case inspection
Introduced in 1969, the first-generation Defy pairs its octagonal case with a matching bezel. Fratello reports 300 m water resistance and an automatic caliber 2552PC running at 21,600 vibrations per hour, with a 46-hour power reserve. These are historical specifications from the guide, not a guarantee that a decades-old example remains water-resistant: do not expose one to water without having its condition and seals assessed by a qualified watchmaker.
The most consequential visual check is the case. Polishing can soften the edges and facets that give the watch its geometry, and Fratello also flags non-original dials as a concern. Request clear, well-lit photos from several angles, paying particular attention to the case edges, bezel and dial. Ask what parts have been replaced and whether service records are available; have originality and mechanical condition assessed independently rather than relying on the listing description.

Fratello says later early-1970s examples used caliber 2562 and notes dial markings indicating 28,800 vibrations per hour; it reports production continuing through 1975. Treat the exact configuration of an individual watch as something to verify against its movement and dial, not something established by an A364x label alone. The guide’s May 2021 estimates ranged from roughly €600–700 at the low end to about €2,000 for a good example; those dated figures are not current market guidance.
El Primero A384: the panda-dial option
The A384 is the most graphic of the three El Primero choices here: its black subdials contrast with a silver dial, while a black tachymeter ring and red central chronograph hand add further definition. Fratello reports approximately 2,600 produced between 1969 and 1972. Its May 2021 guide placed historical estimates at around €10,000 to start, with good examples around €15,000–20,000; the market may have changed substantially since then.
El Primero A385: a warmer, more graduated dial
The A385 shares the A384’s cushion-style case and first-generation El Primero movement, but the smoky khaki-to-cappuccino dial changes the watch’s character. The gradient darkens toward the edge and is paired with white chronograph registers. Fratello reports approximately 2,100 examples produced from 1969 to 1972. Its May 2021 estimate was roughly €6,000–10,000, not a current valuation.
El Primero A386: overlapping registers and a slightly larger case
The A386 stands apart from the A384 and A385 with its 38 mm case and overlapping blue, light-gray and anthracite registers on a white dial. Other reported details include a black minute scale with 100 graduations, a date at 4:30 and a red central chronograph hand. Fratello attributes production of about 4,500 examples from 1969 to 1972 to Zenith. Its May 2021 estimates started around €14,000–15,000 and rose for better examples; the guide described high auction results of roughly €20,000–30,000. These historical estimates are not current pricing advice.
Rank #3
- Used Book in Good Condition
The A384, A385 and A386 use caliber 3019 PHC in the guide’s account. Fratello says the movement was introduced in January 1969 and specifies 36,000 vibrations per hour, 31 jewels and a 50-hour power reserve. It explains that the high frequency permits measurement to a tenth of a second. A 2019 A384 re-edition is also noted in the guide; do not confuse a re-edition with an original vintage watch when evaluating a listing.
A277: a manual-wind chronograph in a more restrained size
The A277 is a 40 mm steel chronograph, 14.5 mm thick, with 22 mm lug width. Fratello describes a Gay Frères ladder bracelet as an option. Its account distinguishes early examples—with non-luminous seconds hands, blued subdial hands and a five-point crown star—from later examples with luminous seconds hands, gold-colored subdial hands and a four-point crown star. It identifies caliber 146H with the first version and 146HP with a later update. Check that the combination on a particular watch is consistent with the version claimed; the presence of one detail by itself does not establish originality.
Faded bezels are commonly encountered, according to the guide, so inspect the bezel rather than assuming a worn insert is an isolated cosmetic detail. The May 2021 estimates were roughly €4,000–5,000 for a beat-up example, around €10,000 for better condition and about €15,000 for pristine examples. They should not be read as present-day values.
A. Cairelli CP-2: the largest and military-associated option
The 43 mm CP-2 is associated with supply to the Italian Air Force through the Roman retailer A. Cairelli. Fratello describes a black dial, two large registers, a graduated rotating bezel, tritium-coated numerals and hands, and an airplane-shaped central chronograph hand. It identifies the hand-wound caliber as 146DP. The guide reports a production story of 2,500 watches, while noting that the number distributed to military personnel versus sold publicly is unknown. A military association does not prove that a seller’s individual watch saw military service; ask for supporting provenance records.

The 2016 Heritage Cronometro TIPO CP-2 reissue differs from the vintage watch: Fratello says it uses an El Primero movement and omits the A. Cairelli name from the dial. The guide’s May 2021 estimate for the original CP-2 started around €10,000 and reached €15,000 or more for better condition. These are dated historical estimates, not current market guidance.

Vintage watches may have replacement parts from service, and Fratello warns that the market also includes fake or “Franken” examples assembled from components that do not belong together. A reference name, attractive dial or seller’s assurance is not proof of originality. Before committing, compare the watch’s details with reliable reference information, ask for service history and a clear account of replacement components, and arrange an independent inspection when the purchase warrants it. The Defy’s case facets and the version-specific A277 details deserve particular scrutiny for the reasons described above.
Zenith’s Extract from the Registers uses case and movement numbers to provide archival information such as model, caliber, functions and production date. It does not estimate value and is not an authentication examination. Zenith distinguishes the extract from its Certificate of Origin, which involves an in-depth examination at the manufacture and addresses whether the movement, case and dial originate from Zenith.
As stated on Zenith’s official Certificate of Origin service page, Certificates of Origin are suspended from May 1, 2026 through April 1, 2027. Zenith says register extracts remain available during that period, but do not replace authentication. Service availability can change, so check the official page before relying on the suspension dates or planning an application. Zenith also describes its ICONS vintage-watch program as offering watches sourced and restored by the manufacture with historical components and traceability; that description does not establish that any particular reference is currently available.

How to choose among them
- Choose the Defy if its angular case is the draw and you are prepared to scrutinize case shape, dial originality and present-day water resistance.
- Choose among the El Primero models by dial and size: the A384 for the silver-and-black panda layout, the A385 for the smoky gradient, or the A386 for overlapping colored registers in a 38 mm case.
- Consider the A277 if you want a manual-wind chronograph in a 40 mm case, or the CP-2 if you prefer its larger 43 mm format and military-associated design.
- Set a budget using recent, comparable evidence rather than the euro estimates in the 2021 guide. No current market-price statistic is established here, and condition, originality and provenance can materially affect the value of an individual watch.
