Seiko Prospex Diver 42mm 1968 Re-interpretation Automatic GMT Watch

Since 1965 when Seiko launched its first nautical watch, it has been innovating with new technologies, features, and designs. The Seiko Prospex nautical watch collection is a top choice for professional and recreational sailors worldwide. Over half a century, Seiko has constantly expanded the limits of sports watches, especially nautical ones. This watch features a 42mm stainless - steel case and bracelet. It is powered by the 6R54 caliber. The buckle is a three - fold clasp with a secure lock and a push - button release with an extender. You can choose from green or black dial colors. It has an automatic movement with manual winding capacity and a power reserve of about 72 hours. The watch comes with a sapphire crystal and LumiBrite on hands, indexes, and bezel. It is water - resistant up to 200 m. Style numbers are SPB381 and SPB383.

Using your Seiko Prospex Diver watch is straightforward. The automatic movement will keep ticking as you move, but if it stops, you can manually wind it. To set the time and date, simply pull out the crown and turn it. For the GMT function, use the crown to adjust the additional hour hand. When it comes to water resistance, it can handle swimming and snorkeling up to 200 m, but avoid pressing buttons underwater. Keep the watch away from magnetic fields as they can affect its accuracy. Clean it regularly with a soft, dry cloth. If you notice any issues with the movement or water resistance, take it to a professional Seiko service center for maintenance.
