That is a little unusual- do you have a shot showing the dial? 955.706 is the correct reference for a bi-metal 1500, but, as you'd know, most don't have a letter after the numbers. I'm also not too sure about that caseback.

Where did you buy the watch?

 

I think it's OK...but just not sure. The caseback should look like this- hard to tell if yours does, as your flash is bouncing off the metal on the caseback

Note this also has the "G" suffix

 

Thanks Mark- it's the only series I can recall with that reference format?

Plus, the pattern background on the engraving of the TAG Heuer logo is unusual for the 1500- quite different to the 2000/4000/6000

I doubt there's any real reason- could be as simple as they wanted to give the 1500 its own style caseback.

Yes, the possible year range on this is quite narrow. The 1500 was launched in 1990 and TAG Heuer began to change the format of their reference numbers in 1992/ 93, when 955.706 became WD1121- so yours is somewhere in between 1990-1993
