History and company information

Zenith Class calibre 680

click to enlarge

Zenith began production in Switzerland in 1865 and are one of the few companies that can call themselves a manufacturer, as they design, manufacture and assemble all components in their own factories. The Zenith Class uses the calibre 680 Elite movement. The creation of which was the result of more than 5 years of research, and is recognised in the horological world as being of unique and of exceptional quality and technical brilliance. It combines qualities of performance, reliability and precision in it’s elegant geometry. To go along with such qualities of the movement, the face of the watch has to really reflect what drives it, and this is precisely the case with the Elite. It is designed in a stylish, classical design, with pearl finish matt silver dial which has got a guilloche centre circle. It is plain and simple, yet unique, appealing and understated in its characteristics. The face is clean, and the design is perfect. The main time hands are gold, and the sub dial hands are black. The seconds is in the sub dial at the 9 position and the power reserve is at the 2 position, these sub dials are recessed to give the dial three dimensional look, which is extenuated by the guilloche centre. The case is likewise well designed and well balanced, with lovely curved angles on the lugs. The winding crown is discreet and small, the case is made of 18 karat solid gold with a solid gold back making the watch quite heavy in proportion to its size. It has nice touches such as the angled date window at the 5 position and the subsidiary seconds at the 9 position and stopping seconds for accurate time setting

Zenith is a company that you would have to invent if it didn't already exist.

Zenith has everything that you can wish for as a collector:

	A long history of high-quality precision watches
	Beautiful pocket watches since nearly 140 years and technological break-through wristwatches in modern times
	The Know-How of a true Manufactory
	An excellent price-performance ratio

Let us have a closer look at these issues:

A long history of high-quality precision watches

High Quality:
In Schmeltzer's "Taschen- und Armbanduhren richtig sammeln und bewerten," there is a table that lists numerous watch brands and indicates which degree of quality their products have. While there are many companies whose products cover the range from "good" to "excellent" or from "simple" to "very good," there is only one entry for Zenith: Very good. The company never cared for mediocrity or mass markets, from the very beginning, they made nothing but top quality.

Precision:
Zenith has a track record for observatory precision prizes that is unparalleled by any other company. The world precision record that the pocket watch caliber 5011 K set in 1969 is still valid!

Beautiful pocket watches since nearly 140 years and technological break-through wristwatches in modern times

When I became interested in (vintage) pocket watches, it was clear from the very beginning that I would look for Zenith watches - and I haven't been disappointed by any of them! 120 year old watches, never serviced, keep time with an accuracy of less than a minute per day without any cleaning or adjusting, but these values can still be improved with some TLC.

The technological break-through needs no further explanation - Zenith's "El Primero" caliber has no competition, the company, however, does not rest on its laurels: The Basel 2002 World Watch and Jewellery Show will see not less than four new versions of this world-famous 36000 a/h caliber.

El Primero

MOVEMENTS

Mechanisms with a soul of infinite scope

El Primero on the move. Here is a creation of quite extraordinary complexity: the first self-winding chronograph calibre with an oscillating weight rotating on a centrally positioned ball bearing, and with all the parts and complications perfectly integrated. It was in March 1969 that it made its première appearance, after more than five years of design and preliminary work. The handsomely scaled calibre has thirteen diameter lines, i.e. 30 mm for a slim 6.50 mm thickness, or 7.55 mm for the instantaneous changeover triple date version. The movement has a column wheel and classical reset hammers and to this day is still the finest on the market. It is also the most accurate of all movements. The glucydur balance wheel combined with a flat spiral spring made from top quality non-magnetic self-compensating Anachron oscillates at a rate of 36 000 vibrations per hour, to produce chronometer measurements accurate to one-tenth of a second.
The movement is not affected by any sudden changes or magnetic fields, and has the best long-term timing ratio in its category. The movement is comprised of 354 parts, and in the most complicated version 277 of these are different parts. There are 41 screws, plus 31 jewels; over fifty different points have to be oiled using ten different grades of lubricant (including four dry lubricants for the high-performance escapement) for the simple version, and another 38 points for the main plate of the triple date mechanism.
This truly wondrous movement requires a total of nine months work, involves between five and fifty separate operations per part, some fifty milling procedures at different points on the dial side and 77 milling procedures on the bridges side. More than eighteen different metals are used to make one movement, combined with the devotion of more than twenty specialist watchmakers dedicated to their daily work. Such complexity as found in El Primero, the movement created by ZENITH, must surely have a soul.
