Doxa Watch SUB 200T Professional Iconic Bracelet 804.10.351.10. The Doxa watches SUB 200T skillfully retains all of the original SUB’s DNA while embracing modern style and sophistication with its smaller diameter. In reworking the spatial volumes inside the case to bring it down to an elegant 39mm diameter and a more wearable thickness of 10.70 mm, DOXA has also tweaked the dial design to achieve a more contemporary visual presence on the wrist.
