I have thought of nothing else but Heuer Divers for the past two days so you will forgive me for taking a short break last night to watch England finally play some real football after a summer of discontent, which provided some light relief but delayed the completion of my report. Jeff has proposed two fundamental questions which I aim to answer and nail down this subject once and for all. They are:

1. Defining a model name/names and
2. The number of entries on the main index page.

The Family tree is as follows:

Heuer Diving Watches

- 1000 Series (automatic & Quartz) + (28, 32, 38 & 42mm case size)
- Super Professional (844.006 + 840.006)
- 980.003 + 980.004 (Day date with crown at 4)
- 980.023 (1000m Quartz crown at 4)
- Ladies (981.058 + 982.058 + 983.058 + 983.048)
- 2000 Series ????????????

These six branches cover all the Heuer diving watches made between the launch in 1979 and the take over by TAG. I have not included the 11063P and 11630P (both of which are Autavias) and I have not elaborated on the 2000 series for reasons detailed below.

By far the majority of Heuer dive watches fall into the first branch, which I am sure, we can all agree on the model name as the 1000 Series. Further confirmation of this is that later watches had 1000 printed on the dial. The defining feature is the case shape. This did not change throughout the years of production and is a common feature in all four case sizes. There were of course subtle changes to the case including thickness and case back but the general appearance is consistent and recognisable as a 1000 Series model.

Next up is the Super Professional with only two variations and with model name printed on the dial. The remaining “three” branches with a total of 7 variations make up the rest of the Heuer diving watches. There is no obvious model name for any of these so I shall refer to them by their reference numbers.

I would like to think that therein lie the answers to the two fundamental questions. The model names are defined (where possible) and Heuer Diving Watches as the single entry in the main index page.

There remains one annoying problem and that is the 2000 series. These first appeared in the 1983 Time for Action catalogue as quartz based chronographs. They featured a new case design with slimmer lugs to the 1000 series. The 1985 Time for Action catalogue featured in the OTD Catalogue section starts at page 51. I have the full scan of this catalogue and it is interesting to note that the cover has the familiar Heuer logo but on the first page we see the new TAG Heuer logo. It also has the full and much enlarged 2000 series range which have the Heuer logo and 2000 printed on the dial. This range is vast and includes the original chronographs plus a full line of sport AND diving watches. This raises some questions namely where these actually made with Heuer dials, do we consider them to be Heuer or TAG Heuer and most importantly do we include these 2000 Divers in the family tree above? I suspect many of you vintage HEUER enthusiasts just don’t care however it is another fundamental questions in order to produce a complete and accurate section on Heuer Divers. So your opinions would be much appreciated. I have included a picture of these just to remind or enlighten you to what I am on about. (Dial says Heuer).

I look forward to your comments on all the above and I will now proceed to complete the master reference table excluding the 2000 series until we agree otherwise.
