Our take on the Seiko Men's 5 Automatic SNK371K Blue Stainless-Steel Automatic Fashion Watch

The Seiko 5 SNK371 is a compact automatic field-style watch with a blue dial, luminous arrow hands and a stainless-steel bracelet. It runs on Seiko's in-house automatic movement with a day-date display and a see-through caseback, so it never needs a battery. At 37 mm it wears small, which suits slim wrists and anyone who wants a simple everyday watch. Against rivals it trades size and simplicity for a smaller dial and basic 30 m water resistance, and the Seiko 5 line is widely respected as an affordable first mechanical watch.

Questions and answers

Is the Seiko 5 SNK371 a good first automatic watch?
Yes. It uses Seiko's proven automatic movement, has a simple day-date layout and a compact case, which makes it an easy entry into mechanical watches.
Can I swim with it?
No. Its 30 m rating covers splashes and brief immersion, not swimming or showering.
Does it need a battery?
No. It winds itself from wrist movement, and the skeleton caseback lets you see the movement.
What is the case size?
The case is 37 mm across and 11 mm thick, with an 18 mm lug width, so it wears small.
Does it have a sapphire crystal?
No. It uses Seiko's Hardlex crystal, which is scratch-resistant but not as hard as sapphire.

This Seiko 5 movement does not hack or hand-wind; it starts from wrist motion.
