Seiko Collaborated with a Famed Japanese Streetwear Brand on These New Dive Watches

Three new digital Prospex “Tuna” models combine dive watch toughness with digital practicality and a wide-ranging feature set.


Seiko teamed up with Japanese streetwear label Lowercase on three new digital “Tuna” dive watches within the Prospex line. Each of the new SKUs features a 49.5mm case with 200m of water resistance and a Hardlex crystal, as well as a quartz-powered, solar-charging movement with EL light, alarm, stopwatch, timer, dual-time display, power save function, full auto calendar, and more.

A world timer allows the user to keep track of the time in 44 different cities, and a handy power and battery level display indicator lets you know when the watch needs some sun. An included silicon strap is perfect for diving and comfortable in and out of the water.
