Seiko 5 Automatic 21 Jewels Gold Tone SNKA10K1 Watch

Automatic Gold-Tone Dress Watch

This Seiko 5 runs on a 21-jewel Japanese-automatic movement that winds itself from wrist motion. No battery is required. The 37.5 mm gold-tone stainless steel case pairs with a matching bracelet and a mineral Hardlex crystal. Day and date appear at three o'clock with the day shown in English or Spanish.

Suitable For Daily Wear

The 30 m water resistance handles splashes and brief immersion but not swimming or diving. Buyers who need a screw-down crown, higher water resistance or a sapphire crystal should look elsewhere. The fixed bezel and dress styling also make it a poor fit for rugged outdoor use or professional timing.

Check Wrist Size And Clasp

The bracelet uses a push-button deployment clasp; confirm it can be sized to your wrist or that a jeweller can adjust the links. The case thickness is 11.5 mm, so verify it will clear shirt cuffs if that matters to you. The exhibition case back means the movement is visible from the rear.
