The watch case is made from stainless steel. Besides the multi-year calendar in the top and the bottom of the dial it has both a date and weekday indicator. It has a selfwinding movement and still a very low profile. It feels like quite a quality watch compared to other cheaper watches from the early seventies. In fact it was a product from japanese watch company Orient – more on this later. The Wittnauer was introduced in 1970/71 and lasted to 1975 when a new version was launched.

Variations
There was both a ”Wittnauer 2000” which had a steel case and a ”Wittnauer 2002” with a golden case. The number can be found on the back case of the watches. It seems that the Wittnauer 2000 with steel case and blue dial was the most common model.
In total these combinations can be found:
Steel case / dark blue dial (Wittnauer 2000)
Steel case / silver dial (Wittnauer 2000)
Steel case / golden dial (Wittnauer 2000)
Golden case / golden dial (Wittnauer 2002)
Golden case / green dial (Wittnauer 2002)

Note a small difference between the bezels on the two models. 2000 has black hour markings on the silver bezel while the 2002 hasn’t got these markings.
Also a womens version were made measuring 32 mm in diameter. The ladies version had only the date on the dial – and not the weekday – due to the smaller size. I have seen these two versions:
Steel case / dark blue dial (Wittnauer 3000)
Golden case / golden dial (Wittnauer 3002)
 |

Wittnauer 2000/2002 in ads
Luckily I have found some ads and materials that can be used to document the model. E.g. notice that the Wittnauer 2000 always was promoted with the metal bracelet as often can be found on the watches that has survived the past 45 years. Furthermore the materials tells the Wittnauer 2000 was also advertised in tv commercials.

The full package
The watch came in a plastic box labeled ”Wittnauer 2000” and inside ”A Longines-Wittnauer Product”. There seems to have been a silver version of the box for Wittnauer 2000 and a gold for the 2002 versions. It had a an outer box made of cardboard.

On the front the watch is called ”perpetual calendar” but in the booklet Wittnauer correctly states that ”thus you can see any day and its corresponding date for any month up to the year 2015.” They are clearly aware that the ”perpetual” part is not totally correct.
Also note that it says in the instructions ”if bracelet model”. This indicates that the Wittnauer 2000 also were sold in non bracelet versions. We have however no documentation of what kind of watch band it alternatively could have.

Small changes from first to later versions
The first generation had ”Patent Pending” on the back of the case and ”JAPAN Y6404-013” at the bottom of the dial. Probably after the patent was granted the back case was changed to ”U.S. Patent NO. 3621648” and on the dial it now only said ”JAPAN”.
I have only seen the ”Patent Pending” version on watches with the steel watch case (2000). Maybe the golden versions (2002) were introduced at a later point when the patent was granted.

The patented calendar
The patent can be seen here. The patent was granted 23 November 1970.
 |
| The drawing in the patent application from 1970. Click to enlarge. |
Note that in the drawing the first year on the calendar was 1960 and the last 1981. In reality it was produced in the Wittnauer-version covering the years from 1971 to 2015. In the description it says: ”the calendar device according to the present invention can be used for about 20 years or even longer as illustrated in the drawings.” How the marketing people were allowed to promote this as a ”perpetual calendar” must be due to the good old American tradition of advertising exaggeration.
From the materials it is clear that the inventor was named Tooru Takagi and was from Orient Watch Co in Japan.
So how does the calendar work?
It is very simple. Rotate the crown located at 4 o’clock and set the present year under the current month (shown in the bottom of the dial). In the top of dial you will then have a calendar showing the dates and the corresponding weekdays for the month. Is 12th October 1980 a Sunday? You will be able to answer that question in a matter of seconds by rotating the crown and changing the year and month (yes, it was a Sunday ;-)
 |
| Set the year under the month in the bottom - and you have a calendar with dates and weekdays for the current month in the top. |
The only problem is that the info on the dial is very small, so this was not a watch for people with reduced vision.
The Japanese connection
On the rotor in the movement it says ”Wittnauer Watch Co.” and ”W102”. In the movement it further says: ”Seventeen, 17 Jewels, Unadjusted, Japan”. On the metal bracelet it says: ”Stainless steel. Made in Japan.” Not hiding the japanese connection.
 |
| The movement in the Wittnauer 2000/2002. It says "W102" and is probably a rebranded Orient 42972. |
The Wittnauer 2000 and 2002 was a white label product from Orient. Orient had a similar model called the ”Y469672-4A”. The Orient normally had a 46941 movement with 21 jewels. I am not an expert on Orient movements but it seems that the Wittnauer W102 movements is in fact a rebranded Orient 42972.
 |
| Orient Multi-Year Y469672-4A the same as the Wittnauer 2000. |
 |
| The movement in the original Orient version had 27 jewels. This source claims that the jewel count were reduced on the Wittnauer version for import duties reasons. |
The first Orient Multi-Year Calendar watch
The Orient Y469672-4A from the 1970s can be traced back to an even older model from Orient called ”Multi-Year Calendar”. The dial had almost the same layout as the later Orient/Wittnauer model but the watchcase was only 39 mm in diameter. Note the years in the calendar – they start at 1960 – indicating that the calendar concept had existed for 10 years in Japan before being exported to America.

Successor from Wittnauer
A couple years later, around 1976, Wittnauer released a new version of the ”Time Machine” with a calendar on the dial. This time it was correctly advertised as having ”thirty years of calendar days and dates” and not as a perpetual calendar. I have only seen few examples of this watch (on eBay) and it can not have been nearly as popular as the predecessor. Size unknown.

An European version: Interpol
I have found this very interesting Interpol Multi-Year calendar watch. Interpol was a brand from swiss Oberon Watch SA (more on this in a future post ;-). The dial on the watch is exactly the same as the original 39 mm Orient and the watch case seems also to be identical. The hands are a little different and the movement in the Interpol is a Baumgartner 158. And on the dial it now says ”Swiss Made”. It can have been a copy - my best bet is that Oberon sourced some parts from Orient, fitted another movement and sold it as ”Swiss Made”.

Newer versions
The russians made ”shameless” copies of the Orient concept. See here for some Raketa’s and a Luch.
 |
| Luch produced from 2003 had a quartz movement. It was almost identical in design to the Wittnauer from the 1970s. |

Final words
If you ever get the opportunity to buy a Wittnauer 2000/2002 at a reasonable price – do it!
