2017 Doxa SUB 300 Professional 50th Anniversary Limited 820.10.351.10

Here we have a 2017 Doxa SUB 300 Professional 50th Anniversary Limited 820.10.351.10, limited to just 300 pieces worldwide. This special edition celebrates the 50th anniversary of the legendary 1967 DOXA SUB 300, a watch that completely revolutionised commercial diving history and became the trusted instrument of Jacques Cousteau and the Calypso crew. The 42.5mm C-shaped stainless steel case sits on the wrist like a classic cushion, closely matching the original dimensions Urs Eschle developed. Polished sides and brushed top surfaces transition with razor-sharp edges towards the stubby integrated lugs, while a compact lug-to-lug length of 46mm and a case thickness of 13mm deliver a remarkably comfortable, historically accurate vintage profile. At 3 o’clock, a screw-down crown fits recessed into the case side for maximum protection and is signed with the iconic orange DOXA fish. The saw-tooth, unidirectional rotating bezel features a dual U.S. Navy No-Decompression chart, with an orange outer depth scale and a black inner minute scale. A highly domed, historically faithful box sapphire crystal mimics the original plexiglass and sits above the iconic vibrant orange Professional dial. Painted black block indices with Super-LumiNova centres mark the hours. A date window sits at 3 o'clock, while the highly functional asymmetric handset includes a small black hour hand, a prominent oversized minute hand for deep-sea legibility, and a black seconds hand with a square luminous counterweight. The vintage-correct dial crosshair features the classic layout: "DOXA" and "automatic" printed in the upper left, with "SUB 300" and "Professional" on the lower right. On the reverse, a screw-down case back proudly displays the historic sailing ship emblem in bas-relief alongside its individual limited edition number out of 300. Inside beats a reliable, COSC-certified Swiss automatic ETA Calibre 2824-2 movement with 25 jewels, running at 28,800 beats per hour. The watch comes fitted with its premium 20mm stainless steel "beads of rice" bracelet with brushed and polished finishing, secured by a signed folding clasp with a dive extension. This watch comes complete with its original Doxa presentation tube and full paperwork.
