In 2011 Panerai introduced the PAM00968 Luminor Submersible encased in a 47mm diameter bronze case exemplified by the present example part of a limited edition of 1000 pieces. Its apt nickname “Bronzo” comes from the Italian word for bronze and from a technical standpoint the watch features an in-house cal. 9010 with up to 3 days of power reserve via two barrels.
