This forum helped me get information about this piece. To give back I put it for sale for a relatively low price here. Heuer Carrera Twin-Time on a rubber strap. Condition is pretty good: Some swirls on the case but everything is easy to "clean". The diameter is approx. 39/40mm. The watch movement is a ESA Quartz which is signed. Priced a very low but firm €1000.- (as we sprak about 1115 USD) Located in EU but I will ship WW. Loads of references on the dutch watch forums.
