Escapement Watch Review: Zenith El Primero 410

Nestled within the 12-hour counter and displayed via a crescent shaped aperture is the moon-phase indication. The disc responsible for delivering the display, decorated with two moons, is driven by a “59-toothed wheel” corresponding to two lunar cycles (2 x 29.5 days).

The date is positioned between 4 o’clock and 5 o’clock, a detail in common with many, but not all, El-Primero models.

The lengthy list of functions is completed with a day and month display located adjacent 10 o’clock and 2 o’clock, as well as a tachymeter scale delivered around the circumference of the dial.


Despite delivering much information, the dial does not unduly overwhelm the wearer. However, I would concede that some other Zenith models, such as El Primero Striking 10th, have less busy dials, courtesy of fewer functions. The potential buyer may wish to consider whether they need the additional functions of the 410 or would prefer a simpler dial display of an alternative El Primero model. I must say though, I don’t bemoan the notion of choice, something Zenith seems to provide in abundance.

Closing remarks

As I looked at this watch, adjacent Lake Geneva, a wonderful view lay in front of me. Yes, the lake is very beautiful, but I refer to the view of the movement, visible via the exhibition caseback.

The oscillating mass is open-worked and decorated with Côtes de Genève motif. The blued screws and the perlage are further testament to the quality of the movement. However, an aspect I particularly like is the visibility of the gear train and levers which, sadly, are often hidden from view.

This is a superb watch and it reminds me of a former horological love. Whether this would be my chosen model from the range remains unanswered. I discern much merit in the 410 but, conversely, see many other models in the Zenith catalogue that also appeal to me. Ultimately, like the Gant store on Regent Street, I know Zenith has much to offer and it is my familiarity with this Swiss brand which will inevitably lead me back to its charms.

    Hey Angus, I hope by now you’ve decided on the exact model of the El Primero. I, like you have gotten rid of my black guilloched with leather strap by trading in for a Patek 5396 (plus $)for my sixtieth some 12 years ago. Just like you, I regretted the fait accompli, which was my fourth, I owned and sold two steel bracelet , one white and one black dial and one rose gold and the aforementioned black guilloched straps, so I got my self the 410 four years ago again… I will be holding on to this one, although I wish I had known about the blue dialed model.
