The Forgotten Weirdo: The Zenith “Null Primero” Espada

The Zenith El Primero Espada kept the high-beat character of the line but dropped its defining chronograph. Here are its reported specs, history and secondhand buying considerations.

The Zenith El Primero Espada was an unusual El Primero: a 2012 time-and-date watch with a high-beat automatic movement, but no chronograph. It kept some of the name’s signature technical character while leaving out the function most closely associated with it.

What was the Zenith El Primero Espada?

Zenith released the Espada in 2012, according to Brandon Baines’s 2021 Fratello feature. It displayed hours, minutes, a central seconds hand and the date. Despite carrying the El Primero name, it had no chronograph function.

That makes the Espada a useful distinction: it was not simply a conventional El Primero chronograph with its pushers removed. It was a time-and-date watch built around a simplified, El Primero-derived caliber. Baines’s account is the source for the model’s specifications here; no official Zenith specification sheet for this discontinued watch was located.

What movement did the Espada use?

Baines identifies the automatic movement as caliber 4650B. His feature reports a 30 mm diameter, silicon escapement, 36,000 vibrations per hour (vph), and a 50-hour power reserve. The movement had 210 components and 22 jewels, compared with 278 components and 31 jewels for the El Primero 400 chronograph caliber. Baines also describes the 4650B as thinner than the chronograph movement.

The 36,000 vph rate preserved a defining El Primero trait even though the watch omitted the chronograph. In his feature, Baines describes the El Primero’s reputation since its 1969 debut as resting on its 36,000 vph frequency and automatic, integrated chronograph design. The Espada retained the frequency, but not that integrated chronograph architecture or function.

How was the Espada sized and configured?

Baines reports a 40 mm case diameter, 48 mm lug-to-lug length, 11.7 mm thickness, 20 mm lug width and 100 m water resistance. These figures describe the model as presented in the feature; confirm the reference and its specifications before applying them to a particular secondhand example.

The reported range included steel, rose-gold and two-tone cases, with black, brown, white, silver and mother-of-pearl dial options. Some versions had diamond markers or diamond-set cases. Buyers could find strap and bracelet configurations. Those variations matter: material, dial, setting and bracelet can make two Espadas look and wear quite differently.

Why was the Espada called a “Null Primero”?

The nickname points to the tension between the El Primero name and the Espada’s time-only-with-date function. For enthusiasts who associated El Primero primarily with a high-beat integrated chronograph, a watch without a chronograph could feel like an expectation mismatch. That is Baines’s interpretation of the model’s reception, not a measured consensus.

The Espada name itself had appeared on earlier watches. Baines says an earlier, more complicated El Primero Espada combined a chronograph with a triple calendar and moonphase; later Espada versions became quartz watches. The 2012 model therefore sat within a varied family rather than extending one unchanging design or complication.

What came after the Espada?

Baines reports that Zenith discontinued the Espada in 2014 and introduced the El Primero Synopsis. The Synopsis used an open-heart display and the simplified caliber 4613; the feature gives that movement 160 components and 19 jewels and describes the watch as a short-lived follow-up. Baines also noted in 2021 that Zenith had not released another non-chronograph El Primero by then. That statement describes the situation as of his article’s publication, not the present day.

What should you check when buying a used Espada?

Listings observed on Chrono24 on October 8, 2026 show that Espadas continue to appear on the secondary market. A few individual examples were listed at $3,481 for steel, $6,500 for two-tone and $10,321 for rose gold. These are asking prices for particular listings, not a market valuation or a representative price range; configuration, condition, service history, seller terms and availability differ.

  • Reference and configuration: Match the case material, dial, markers and strap or bracelet to the exact reference. Do not assume every Espada shares the same details.
  • Condition and service: Ask for clear photographs, service documentation and information about timekeeping and function. The cited listings do not establish a consistent condition or service standard.
  • Box, papers and seller terms: Check what is included, along with shipping, returns and seller location. Some observed listings lacked the original box or papers.
  • Price context: Compare like-for-like examples rather than treating one listing as the going value. The observed figures can change as listings sell, expire or are revised.

For current examples, consult Chrono24’s Espada listings and verify each listing’s details directly.
