I know the ones you mean. Steer well clear of those Chinese 'time only' Heuers. I believe they are redials with non-Heuer signed mvements.
I actually have an genuine model from the 50's and the movement is signed. Only some of the very early 30's models don't have signed movements (I have one of those too).
: I'm sorry i don't have a link. The period i'm interested in is the
: 50's and 60's. The one on ebay comes from a chinese seller and
: every time it sells another one appears for sale the movements
: are never signed and too me the heuer logo looks a touch
: lopsided so i'm a bit suspicious. Any info on time only model
: would be appriecated thanks.
