that's a great looking chrono, combining some elements of the older Heuers with some more modern elements.

here is what I have learned:

• Calibre 283 [combination of ETA 2892 and D-D 2000 (designed by D-D and built by Lemania)]
  
• 40 jewels
  
• introduced in 1984 made through approx. 1990
  
• sold for $695 (new)
  
• uncertain of current prices

: Hi

: I have had a Heuer 2000 Automatic Chronograph
: model number 173.006 for the past ten years
: and am thinking of trading it for a Kirium
: F1.

: Unfortunately I know very little about the
: Heuer. Believe the watch is 100% original
: with Heuer parts, the word TAG is nowhere to
: be seen. Still keeps perfect time although
: if not worn tends to stop after nearly 2
: days. Can anyone tell me anything about this
: watch, age ? movement ? aproximate value (as
: new or now).

: Many Thanks.
