This Seiko automatic watch has been dubbed "The Stealth" by fans: its monochromatic colors are inspired by the classic original 1960s designs of Seiko 5 Sports.
The modern materials and finishes used accentuate the depth of the black dial and its rich texture.
The watch is powered by a 4R36 automatic caliber which offers a 41-hour power reserve and a water resistance of 10 bar.
The "hacking" second hand stops when the crown is pulled out, which means it's easy to synchronize with a time reference: hacking is the ability to set a second hand and hour and minute hands.
This model was created with a military design inspired by a trench clock created to be robust and reliable in difficult conditions.
From our Seiko 5 Sports "Field" collection, this watch was created with a military "in the field" design - taking inspiration from a style originally called a "watch."
