The Spinnaker Dumas GMT SP-5119-55 is a great, GMT diving watch with an impressive 300 meter water resistance and a sapphire crystal. Under the hood is an automatic Seiko NH34 GMT movement (which is visible through the display caseback). The watch has a bi-color glass bezel, steel bracelet and a lovely dial that gives the watch a spectacular and legible look. An additional rubbers trap matches the colors of the watch nicely. An incredible watch suitable for all your adventures!
