37 mm Automatic Dress Watch

The Seiko SNK355K1 is a 37 mm stainless-steel dress watch powered by the automatic calibre 7S26 with 21 jewels and a 40-hour power reserve. Its silver dial carries index markers and a day-date window at three o'clock under a mineral crystal. The integrated bracelet secures with a deployment clasp for a clean wrist presence.

Suits daily wearers wanting mechanical simplicity

This piece fits professionals or collectors who prefer a compact, self-winding watch with day and date readout and 30 m water resistance for hand-washing splashes. Buyers who need higher water protection for swimming, a sapphire crystal, a hacking seconds hand or a larger case diameter should look elsewhere.

30 m water resistance sets the usage limit

Rated at 30 metres or 99 feet, the case withstands only incidental moisture such as rain or hand-washing and is not suitable for swimming, showering or diving. This single specification decides whether the watch matches the buyer's daily environment.

この商品に関する質問

What wrist size does the 37 mm case with 11 mm thickness suit?

The 37 mm diameter and 11 mm profile fit small to medium wrists comfortably; the stainless steel bracelet adjusts by removing links.

How do I start the 21 jewel Cal. 7S26 automatic movement after it stops?

Turn the crown clockwise about 30 turns to wind the mainspring, then pull the crown to set the day and date at the 3 o'clock window.

When should the mineral crystal or gaskets be replaced to keep 30 m water resistance?

Have a watchmaker pressure-test the seals every two to three years and replace the crystal if scratches affect legibility.
