I'm not sure there is any premium for the "Heuer" only version- yet. As well as being nice because it only has Heuer on the dial. I think this first version of the watch is the nicest looking- has the cleanest dial without the Monza name.

The watch has a high-shine finish on the sides and a brushed finish around the case. If you're fussy, you may find that most second hand versions with had marks on the high-shine finish- its quite easy to mark.

Whether this watch will ever turn out to be an investment, only time will tell. But I would bet that if it does, it will be the "Heuer" only model that will be worth more.
