I had originally found a case for one of these rare 90s Tag Heuer prototypes about 5 years ago in Australia but could never find the rest of the parts (odd dial) to put it all together, so I sold the parts about 2 years ago. I have only seen 1 other completed running one on eBay in the past 8 years so when this one can up -I put it a real high snipe and got it. The stainless case is around 41mm side to side with a rotating bezel. Now I know that this could be a real love or hate design (Tag apparently couldn't sell them) but it is unique enough for me - its beyond funky! So if you don't like it, I will understand. Fear not, the rest of my Heuer collection are winders. Craig
