UK POSTAGE ONLY FOR THIS ITEM
The watch has a 17-jewel calibre 345 automatic movement which is working nicely. The movement is fully signed, and it has the serial number 13,401,308 which dates it back to 1966.
The watch measures 35mm diameter excluding the original Longines winding crown and the lugs.
The case back has the Flagship logo, just traces of the original blue enamel left. There is also a 1966 long service inscription.

The lens is in good condition.
The signed dial is in its original finish with original hands, centre seconds and a date display (initially set by turning the hands just past midnight so the date clicks over, then go backwards to 9pm, and forwards again to click over. Keep going until you reach the desired date).
A new leather strap has been fitted.
The watch comes in a new presentation box.
