The Naviquartz is accompanied by an Extract from the Archives confirming production in 1976 and sale on August 27th of that year. The Pendule Carré is accompanied by an Extract from the Archives confirming production in 1959 and sale on February 11th, 1960. The Naviquartz Certificate of Origin confirms that it originated with black Roman numerals. The Naviquartz is currently running as it has new D size batteries. It might need service soon, however. The dial is very nice and clean. The case is generally nice with some minor scratches to the gilt metal bezel. The wooden outer box has some scratches and wear, however it is generally very nice. The solar clock is not running, as it is lacking a battery. The mechanical part of the movement appears to be in good order, however we cannot be certain of that without a battery to transfer power to the winding mechanism. The dial has some discoloration on it, particularly to 1, 3 and 11 o'clock. The case is in nice condition with some light tarnish and spots to the gilt brass. Please note that the reference number for the pendule carré is 902.
