The outer rim features precise minute tracking for accurate time recording at a single glance.

Case Features

Crafted from solid stainless steel, the compact case offers impressive structural integrity while maintaining balanced wrist proportions. The dial is protected by Seiko's signature Hardlex crystal, which provides superior resistance against scratches and accidental impacts.

Movement

At the core of the SNK51J1 is the legendary Seiko Caliber 7S26 automatic movement.

With an approximate 40-hour power reserve, it delivers reliable timekeeping accuracy without ever requiring a battery replacement.
