Up for grabs is my 300 Black Lung. I am the original owner and it has been worn gently. Running as it should, being it’s only a year old.

Like the original SUB 300, the case of the modern special edition is machined from a solid block of stainless steel, measuring 42.5 mm in diameter, and 13.4 mm thick. It is powered by a chronometer-grade ETA 2824-2 automatic caliber, and finished with a generously domed bubble sapphire crystal and DOXA's signature stainless steel "beads of rice" bracelet which tapers to an integrated wetsuit extension.

Price is $2550 delivered CONUS (happy to ship worldwide but additional shipping costs to be added). Years of references worldwide on here and the other major forums. No regrets here!
