The Seiko Prospex SNJ033 is a solar-powered analog-digital diver's watch that commemorates the 40th anniversary of the 1982 H558-5000, the world's first analog-digital diver's watch with a chronograph and alarm. Powered by light energy, this watch requires no battery change and has a 5-month power reserve once fully charged.

The watch features a chronograph function, black uni-directional rotating elapsed timing bezel, and a black dial. It also has a diving log, depth meter, and sudden descent alarm, along with a water temperature measurement function. The power reserve indicator, local time indication mode, alarm, digital time, and date indicators are some of the other features that make this watch a practical choice for divers.

The watch's digital display is enlarged for improved visibility, and the LumiBrite hands and markers make it easy to read in low light conditions. The watch is water-resistant to 200 meters (660 feet) and follows ISO standards, making it suitable for scuba diving.

The Seiko Prospex SNJ033 has a 46.9mm stainless steel case and bracelet with a tri-fold push button release clasp with secure lock and extender. The screwdown crown, pushers, and caseback ensure the watch's water resistance.

The watch is powered by Caliber H855, a reliable and accurate movement that is known for its precision and durability. The Seiko Prospex SNJ033 is a stylish and functional timepiece that is perfect for those who demand the best in performance and design.
