The Zuccolo Rochet Company was founded in 1904 in Annecy. Their location near Lake Annecy led to the creation of robust, accurate, and reliable diving watches for professional divers. In 1963, the French Navy ordered the design of diving wristwatches that could meet their rigorous specifications, which led to the creation of the Grands Fonds 300.

The ZRC Grands Fonds 38 Heritage 300 Ref GF38263-S3 features a 39mm stainless steel, a domed sapphire crystal, and an aluminum bezel insert with a 60-minute track.  The black dial features lumed hour plots, pencil-shaped hour and minute hands, and a lollipop-shaped seconds hand, with a date window at the 3 o’clock position.  The crown is at the 6 o’clock position and features a safety mechanism that will not allow the
user to close the bracelet unless the crown is fully screwed into place.  Powered by a Sellita SW200-1 automatic movement, the GF38263 has a 38-hour power reserve and a water resistance rating of 300 meters.

This ZRC Grands Fonds 38 Heritage 300 Ref GF38263 includes the outer box, the red ZRC watch case, the warranty certificate, the user manual, the serial number hang tag, and the original stainless steel bracelet.
