One of the rare models (06.0250.400) of the so called Italian El Primeros and with the rarest blue dial of that model. These were not mentioned in any standard Zenith catalogues or promotional material. They all have 06 in the beginning of the reference and are made of 18K gold. Also indices and hands are made of solid gold.Comes on a non-original vintage leather band with original gold plated Zenith buckle. The watch weighs approximately 60g without strap and there is no inner case in other metals than 18k gold. That means that you will be wearing roughly 45g of 18k carat on your arm! To the best of my knowledge the watch is completely original including the 18K gold crown. Very good condition overall with good time keeping and chronograph working perfectly. Some were slight hazing on the inside of the sapphire glass. Service history is not known and a checkup/service at a watchmaker is recommended. Please, do not hesitate to contact me if you have any questions! The item "Rare very heavy blue dial Zenith El Primero in solid 18K gold (06.0250.400)" is in sale since Thursday, September 9, 2021.
