Last year, DOXA hit a home run with their now sold out 50th Anniversary SUB 300 Professional “heritage” reissue, a watch that honored the original DOXA Sub to a tee (pun intended). Today, DOXA is following up with a grand slam of an announcement with the DOXA SUB 300 “Black Lung” limited edition, a watch that celebrates DOXA’s important relationship with Aqua-Lung–the renowned scuba gear company–as well as a historic and rare diver born of that partnership. Aqua-Lung pioneered the first self-contained underwater breathing apparatus (SCUBA), which of course led to expanded possibilities for underwater exploration and to a boom in recreational diving. In 1967, DOXA introduced the first SUB, a specially designed tool watch for divers, and it quickly gained the approval of those early diving pioneers. Later that same year, DOXA and Aqua-Lung would team up to create a prototype SUB with a yellow and black Aqua-Lung logo printed in the lower left quadrant of the iconic orange dial.
