Build Your Own Datejust Seiko Mod

Start with a Datejust and make it yours. Pick your dial, bezel and bracelet in the builder above, and we assemble it to order by hand in Canada. Every men's Datejust runs on a Seiko NH35 automatic movement, which winds from your wrist and needs no battery. Our ready-made designs include Roman numeral, gem and two-tone gold dials, and we also build ladies' Date-Just styles, which use the NH05 automatic movement. Your watch ships in 2-3 weeks and arrives in a NorthernHour watch box with a care cloth, a sizing tool for compatible bracelets and a 1-year warranty.
