Hi Warren,
For ease of identification by other OTDer, as your pics are on separate threads, I've grouped them together here:

OTDers.. please chip in with your thoughts!! Can anyone ID the movement? Valjoux? It is marked "seventeen 17. jewels Swiss"

From what I've seen so far, it I would be fairly certain that unfortunately this isn't an original Heuer pocket watch from the 80's, but would like others to chip in - happy to be proven wrong.

So.. to re-cap..
- Bought in early 80's by your Father.
- Booklet is marked 721.208, which is for the Golden Hours wristwatch from c84-6, so doesn't belong with this pocket watch. Here is the 721.208 in the catalogue: http://onthedash.com/Guide/_Catalogs/1984_Chronograph_Catalog/69.jpg

- The box, as mentioned before, is unlike any Golden Hours box, or any box from Heuer in the 80s (or ever? Seems that the box is trying to mimic being 'very old' but the logo is the type Heuer used much later on??)

- The logo on the inside of the box - ditto as above, and is poorly executed, spacing of wording under shield is off, highly unusual.
- Round date window - Heuer never, as far as I know, never used a round window.
- The Heuer shield on the dial is worryingly misaligned, it's quite a fair bit off going by the closer up photo.
- Movement is not signed, case is not signed.
- Moonphase has strange 24 hrs markings, Hands not 'en vogue' with other Golden Hours.
- Moonphase disc artwork very unusual, not in-line with other Golden Hours.
- Tachy scale around edge of dial, very strange choice for a pocket watch.
- No lid that closes over the crystal.

Generally speaking, the special edition pocket watches that Heuer released were of a very high quality, they really are stunning, the attention to detail is astonishing. They were like a showcase and some solid gold variants were very expensive, fully signed, cases delicately marked etc etc.
Yours, no offense, is lacking some of these merits. The numerals on the sub dials are of a modern typeface, whereas the outer hour Arabic numerals are period vintage style, it doesn't quite add up.

Here are Warrens Pics.. and I've added a closer up pic of the dial detail.. (hope these work!)
