I just bought this without a case-back so I took the back off another TAG Heuer 1000 and this one runs!

I’d like to identify it so I can hunt for a correct case-back. Barring that I’ll hunt for a case-back only from any 1000 just to keep it utile.

Thank you.

 

Ref 980.021
Since it's TAG Heuer branded, rather than the older Heuer branded model, it probably should have letter suffix at the end. Most likely 980.021N.

 

With its 955.122 movement it should be a 980.021L rather than a 980.021n. If it had the 955.114 movement it would be an N.

The L models used the 955.122 movement when serviced by Tag which replaced the ESA 963 series movements. Tag usually installed the smaller screw down crowns at the same time which this appears to have already.

The L models had a slightly more domed caseback to clear the taller movements. An N caseback would not leave enough room.

Thanks,

Thanks Justin, you're the expert. Curious how you could tell which movement from the pic that was shown.

EDIT: I guess the small crown was the main clue that it's the L?

 

That was a clue but the owner told me in an email that it had the 955.122 but then came here for a second opinion.
