Doxa Watch SUB 600T Sea Emerald Nato 862.10.131.26-N. DOXA is doing more than just revisiting a chapter written long ago. They are paying tribute to the iconic SUB 600T with a new history that begins now. After the massive success of the limited titanium edition SUB 600T Pacific Blue this summer, DOXA is bringing out the SUB 600T in a non limited edition to complete the DOXA SUB line up. The reborn SUB 600T comes in stainless steel with the choice of a steel or black ceramic bezel insert, vibrant colors and either a stainless steel bracelet or a NATO strap to match the dial color.
