The Conger Nero Chronograph Automatic Wristwatch was named after the fearsome eel-like predator of the sea – up to 10 feet long and with a set of razor-sharp the conger – when cornered – has been known to attack divers, too. Our CONGER NERO AUTO was manufactured in a Limited Edition of 100 pieces only; it is water resistant to 2000 meters and as fearsome in its appearance as its namesake: the black DLC (diamond-like-coating) is highly scratch resistant and ensures your watch will keep its pristine appearance for many years. The Conger Nero Chronograph Automatic Wristwatch is a professional grade diving instrument of formidable dimensions.  It may be the largest diving watch I have seen to date!  Please understand the size of this watch before you purchase it 🙂
