Zenith El Primero Limited Edition No. 2 of 400 Ref 30.0220 400 18ct c1993

Zenith

Zenith is one of the oldest watch companies, est. 1865 and one of only a handful which still produces all its own mechanical movements today. The company has an almost unparalleled record of technical achievements. Notably, in 1929, Zenith won world renown at Kew Observatory (England), when a Zenith wristwatch won first prize for accuracy of better than 0.6 seconds per day.

During the late 1940s and throughout the 1950s, Zenith held the lead in producing many of the most commercially successful and most advanced chronograph wristwatches. The technical expertise and craftsmanship which went into these was immense. Just a brief look inside the case-back of any chronograph is enough to demonstrate how complicated these watches are – making these very expensive watches to design and produce.

Zenith has also been recognised with more than 1500 awards and has over 50 individual movement designs to its name, making it the Swiss brand with the most awards for precision.

Descripton

Put simply, in 1969 Zenith produced the world’s first automatic chronograph, the El Primero. This movement was a tour de force and so advanced that almost 20 years later in 1988, when Rolex required a more advanced movement to install in its Daytona Chronograph, it chose to fit the Zenith El Primero movement. It then continued to do this right up and until the year 2000 when Rolex finally began to make its own chronograph movements for the Daytona for the first time.

Many see this as one of the best chronograph movements ever produced, as it can accurately measure time to 1/10th of a second. Even today very few chronographs are capable of achieving this.

This incredible example of the Zenith El Primero is in absolutely immaculate condition. This limited edition model is very rare and is number 2 of only 400 ever made.

The Dial

The original, unrestored and untouched white dial is absolutely stunning and matches perfectly with the 18ct yellow gold case. The triple register dial carries original gilt ‘stick’ hands and ‘baton’ hour indices, along with a date window in the unique position between 4 and 5. It is beautifully symmetrical, well balanced and proportioned. It may initially look quite complicated, but this is because it conveys a lot of information. In actual fact, it successfully conveys all this information very simply, once you become familiar with the layout.

The dial we have here is of course, the more sought after triple register. These registers measure constant seconds at the 9 dial position, minute recording at the 3 position and hour recording at the 6 position. The constant seconds dial runs constantly and independently of the other functions while the large centre hand and the other two registers operate while the chronograph is operating.

The dial also carries an outer tachymeter scale. A tachymeter scale measures speed based on time travelled over a fixed distance, i.e. as a rangefinder – typically in a military application; especially naval gunnery and anti-aircraft artillery – or to measure how far away a storm is, by using the difference in time between the arrival of a flash of light and its associated sound.

As mentioned above, only 400 of this model were ever produced and this is just number 2 of 400, as indicated by the number 2 to the left of the lower subsidiary dial.

As the dial is original and unrestored, this has been left untouched by our restoration team due to its superb condition. Usually, we restore the dials of the watches we sell, however we decided in this case to leave it alone. It also helps to contrast with almost all of the other watch dials you see on our website, which have been restored. The hands, likewise, have also been left in their original condition.

The Movement

As mentioned above, the El Primero movement was a ground breaking achievement for Zenith. First launched in early 1969, it was not only the world’s first self winding chronograph, but it also accurately measured time to 1/10th of a second and also included a quickset date function.

It may perhaps help to fully appreciate the watch movement if we outline a few terms. First of all, simple hand-wound watches are known as a ‘time only’ watches, because they simply tell the time and have no ‘complications’.  A time only watch with a date function is said to have one ‘complication’. If this movement then indicates the day, date and month, then it is said to have three complications.  Moonphase and chronograph functions are obviously a further two complications, as are a self-winding function and a quickset date function.  So this watch, as you will see, has five complications in total, making it highly impressive, particularly as it is based on such an accomplished chronograph movement.

As mentioned elsewhere on our website, it is very important when considering a triple calendar chronograph to find one in tip-top condition which has been well cared for and properly serviced. This is just such an example with each of its functions working perfectly.

The chronograph function works in the usual way and is started and stopped using the top right hand button. It is then reset using the bottom right hand button.

Please note – it is important not to leave the chronograph timer function running in normal use as this will cause unnecessary wear on the chronograph parts of the movement.

The El Primero remains the only mechanical movement ever which is able to measure time intervals to within a tenth of a second. In fact this 31 Jewel movement was so advanced and such a technical tour de force, that when in 1988 Rolex decided to replace its ageing hand-wound Valjoux Cal.72 movement in its Rolex Daytona chronograph with an automatic movement, it chose to buy and fit the Zenith El Primero movement. Rolex then continued to use this movement until the year 2000 when it finally began to produce its own chronograph movements.

As expected, the movement of this watch is in first class condition and has been fully overhauled and serviced by our vintage chronograph specialist master watchmaker. This involves complete disassembly of the movement to each of its component parts. It has then been cleaned and closely examined under high magnification, then re-assembled using only the correct Zenith replacement parts where necessary, and specified oils and adjustments as required, before final testing and calibration.

Following careful timing and calibration, this watch is currently running within +5 seconds per day averaged over 6 positions. This is truly outstanding for any watch of this age and this movement also has a 50-hour power reserve when fully wound.  We are therefore more than pleased to offer 12 months’ warranty on this watch movement*.

The movement is correctly signed ‘Zenith’ and ‘Swiss Made’, ‘31 Jewels’ and ‘ Chronometer’ with the Calibre No 400 and the movement serial number 51137943.

*Please note – our 12 months’ warranty is only applicable if the full list price is paid.

The Watch Case

The substantial 18ct yellow gold watch case measures 40mm in diameter, excluding the original Zenith signed winding crown. The case is in almost perfect condition with no evidence of anything other than careful use and very gentle hand-polishing. It is completely scratch free and the lugs are sharp, with almost new edges. The chronograph pushers are also in immaculate condition, indicating the watch has seen very little use.

The case-back is of full thickness and shows no signs of wear visible to the naked eye. It is correctly signed ‘Zenith’ and ‘Swiss’ with the model number 30.0220 400 and an 18K hallmark. The outside of the case-back also carries a map of Switzerland and the inscription ‘700 ans Confédération Helvétique’ (700 years of the Swiss Confederation).

Please note – as ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.
