I need some help. Saw a Concord Chronograph today, allegedly with a Zenith movement, round, white face. Chrono's were at 12, 6 and 9, with date around 3 and Concord logo as well. Does anyone know the model it could be or pricing? The numbers were silver, as was the hands. It was allegedly $4K asking, down to $2500 and probably about 3-5 years old. It is quite stunning. The white dial almost looks like it has a sheen to it, but is not MOP. Anyone?
