Zenith

The Pilot Collection

 

The focus of Zenith’s offerings this year were perfectly clear even to the least sensitive and uninitiated person once the booth was entered:




The company reconsidered its rich history in aviation timekeeping which encompassed board instruments like altimeters and dash clocks as well as precision pilot’s watches with chronograph and/or world time function. The watch on the left is the timepiece worn by Louis Blériot during his heroic first crossing the Channel – 40 kilometres of ocean – in a flying machine:

 “I am very satisfied with the Zenith watch, which I usually use, and I cannot recommend it too highly to people who are looking for precision” [Louis Blériot on 19 March 1912]





A few years later, as of 1939, Zenith presented a new dashboard instrument, the Montre d’ Aéronef Type 20 which became standard equipment for French aeroplanes at this time - lauded by aviation builders and professionals alike for its reliability, sturdiness and accuracy (bimetallic balance wheel coupled with a self- compensating, anti-magnetic hairspring and a Swiss lever escapement).




It was this exact watch that inspired Zenith to create a tribute to its ancestor, the new


Montre d’ Aéronef Type 20




‘Oversized’ is certainly an adequate adjective to describe a 57.5mm wristwatch (or clock?). And ‘oversized’ watches were the trend of the recent years, fueled by numerous offerings from 700€ ETA 6498 driven watches to creations of respectable houses. But 57.5mm? Now that the trend is fading/reversing?

Well, the bottom line is: THIS WATCH MAKES SENSE!

First, it’s a true tool watch and thus in a different league from its mere mortal wristwatch competitors. Second, its size is determined by the magnificent and certified outstanding Chronometer calibre 5011K, which has a diameter of 50mm. Third, it’s a collector’s item just because of point (2).




The Cal. 5011K  is a renowned Chronometer grade movement used as well in deck and dashboard Chronometer clocks. Here is the fully data set: 
  • Movement: 5011K, manual 
  • Caliber: 22``` (Diameter: 50 mm) 
  • Thickness: 10.00 mm 
  • Components: 134 
  • Jewels: 19 
  • Frequency: 18’000 VpH – (2.5 Hz) 
  • Power reserve: min. 48 hours 
  • Breguet spiral 
It was originally introduced around 1960. It's so well designed that it holds several chronometric records. In 1967 it was named the most accurate chronometer ever tested by the Neuchatel Observatory. It is considered the most precise movement in the world in its category. 

The calibre has been in continuous production since then and used in competition timepieces, marine chronometers, pocket watches, and watch making school watches. Only 50 or so can be made per year.

“Oscillating at 18,000 vibrations per hour, the 5011 calibre has a separate mechanism for stopping the seconds hand and synchronising the hour. It features shock-absorbers on the balance-wheel and escapement [-wheel] arbours [see arrows in image below!], fine adjustment, and a self-compensating anti-magnetic Breguet overcoil balance spring, as well as a mobile stud-holder, double-arrow index regulator, and the Zenith winding-crown stem attachment system. All these assets combine to ensure that the watch gives a first-rate performance without losing its vintage feel.” [Press Kit, corrected!]
 




“The notched crown is reminiscent of those on antique aviator watches, which allowed pilots to set the watch without taking off their gloves. The 27 mm space between the lugs accentuates the shape of the extremely refined lugs that attach an antiqued leather strap sewn and topstitched entirely by hand. Adding to the vintage feel is the black dial, which is easily readable thanks to luminous elements. Beneath the impressive sapphire crystal (glare proofed on both sides), the raised numerals of the chapter ring are made of entire blocks of Superluminova. The time is indicated by hands that are also enhanced with luminescent material.” [Press Kit]




It's an exceptional watch that really looks, feels and sounds like a true chronometer (listen carefully, we could not stop discussing the piece ;-():


Now to the question you all were waiting for: How does it wear? After all, the proof of the pudding as they say, is in the tasting.




Our answer is: it depends. On your wrist, your shirt, the light, the angle of view, your taste. Certainly (and surprisingly) its not too heavy (probably thanks to the shallow case). But the light can make the difference between wearable…




… just ok…




… and simply too big:




The Montre d’ Aéronef Type 20 comes in a limited edition of 250 pieces in titanium and 70 in red gold. A pity that we could only inspect the former one. The titanium version is closer to its original conception, likely lighter and may even sound better.


Big Date Special
In a comparatively ‘diminutive’ size of 42mm Zenith presented its Pilot Big Date Special watch with en El Primero calibre. The case is crafted with classically styled alternating polished and satin-brushed finishes that match well with the matte black dial (sandblasted five times!).




The chronograph comes on an ‘antiqued’ calf leather strap or on a Milanese-style steel bracelet, both of which are good choice for this type of watch.




An interesting detail (which is also present on the Aéronef) is the technique behind the luminous material. Instead of luminescent paint the raised numerals are made of entire blocks of Superluminova:




It's pleasant to wear on the wrist, even if the date window looks much like an (superfluous) afterthought:





Doublematic
Last of the three novelties in the Pilot collection is the new Doublematic, an automatic chronograph with a world time and a big date display as well as an alarm function.




The world time function is a classical two-disc implementation, whereby the one disc at the flange reveals the time in each iconic city, while a second disc indicates day or night.

The movement it built upon the El Primero chronograph with a seconds and a 30 minutes counter as well as 50h of autonomy. A second barrel drives the alarm function, whose status is indicated at 08:30 (on/off window) and 07:30 (alarm power reserve), respectively. A second hour hand (below the main hour hand, with a red tip) indicates the alarm time. The alarm acts – like the Blancpain Alarm GMT watch – on a gong encompassing the movement. It’s rather loud and with a pleasant sound.

The case is rather large with 45mm and comes in either red gold or steel. It’s a worthwhile travel watch and offers – like the mentioned Blancpain – enough versatility to accompany a seasoned traveler for both casual and more formal business use. Our only criticism is that a power reserve for the main train is missing: What is a power reserve for the alarm worth if you cannot gauge whether the autonomy of the main clockwork is sufficient to trigger the alarm the next morning? The same applied to the Blancpain, btw.
