SEIKO Prospex "Arnie" SNJ025P1 Black - Solar Diver Tuna Reissue Watch

The Seiko Prospex SNJ025P1 is a modern reissue of the legendary "Hybrid Diver," originally launched in 1982 as the world's first watch to combine analog and digital technology. Nicknamed the "Arnie" after Arnold Schwarzenegger, who wore the original in films like Commando and Predator, and affectionately called the "Tuna" by collectors for its bold, tin-like case shape, this model carries decades of cult status into a modern, solar-powered package. The striking all-black design pairs a stainless steel case with case guard, luminous hands and hour markers, and a comfortable black silicone dive strap.

Powering the watch is Seiko's Caliber H851, a solar movement that eliminates the need for battery changes and delivers roughly six months of power reserve on a full charge. Beyond standard timekeeping, the H851 equips the watch with a genuine chronograph (up to 100 hours in 1/100-second increments), daily alarm, full-auto calendar (accurate to December 31, 2100), dual time display, battery life warning, LED illumination function, and a power-save mode, all presented through a combined analog-digital display beneath a durable Hardlex crystal. The case measures 47.8mm in diameter and 13.8mm thick, with a 50.5mm length, giving it the substantial, unmistakable "Tuna" presence the design is known for, while weighing a manageable 114.0g.

True to its diver's watch heritage, the SNJ025P1 is ISO 6425 rated, with 200m (20 bar) water resistance, a screw-down crown and screw case back for secure sealing, and a 120-click unidirectional rotating bezel for dive timing. The 22mm silicone strap with buckle closure is built specifically for comfort in and out of the water. Accuracy is rated at approximately 15 seconds per month.
