This is a VERY uncommon circa 1984 HEUER titanium quartz chronograph in 18k. gold measuring 37.75mm. and is extremely light-you barely notice this watch on your wrist! This watch was priced just under the solid gold HEUERS when it was new. These were produced for a VERY short run. The gold bands are solid 18k. inbetween the links. This watch came from a new old stock HEUER batch of watches that were obtained from an astute collector. The watch looks essentially new with handling marks only. We even had the high quality HEUER quartz movement cleaned and is accurate with the chronograph functions working perfectly. The bezel turns. This watch will fit up to a 6.75 inch wrist. This is a fantastic and uncommon HEUER you will love wearing daily. This watch is priced VERY well. I would act fast.
