Dress Watch for Everyday Wear
The Citizen Zenshin is a dress-style watch built for daily use. Its round green dial with index markers gives a clean analog display suited to professional and casual settings alike.
Automatic Movement Constraints
The 8213-A21 caliber runs on wrist motion and stores power in its mainspring. Without regular wear it will stop and require manual winding or a shake to restart. The date window advances once per cycle and cannot be quick-set independently.
100 Metre Water Resistance
Rated to 100 metres the case and sapphire crystal handle swimming and surface snorkelling. It is not rated for scuba diving or high-pressure water jets so keep the crown pushed in when wet.

Questions about this item
Should I choose the 40.50 mm case or a smaller diameter?
The 40.50 mm case sits flat on most wrists and the Super Titanium bracelet keeps it light; try it on if you prefer a more compact presence.
How accurate is the 8213-A21 automatic movement in daily wear?
The 21-jewel 8213-A21 calibre typically runs within a few seconds per day and winds from wrist motion, so it stays ready without a battery.
What does the 100 m water-resistance rating allow me to do?
100 m covers swimming and surface snorkelling; the screw-down crown and sapphire crystal maintain the seal, but it is not rated for scuba diving.
