Classic Sun & Moon Automatic Watch

The Orient Classic Sun & Moon is a dress watch for men who want a traditional mechanical timepiece with a day-night indicator. It runs on the automatic F6B24 calibre with 22 jewels, so it winds itself through wrist motion. The 42.00 mm stainless-steel case and white dial with index markers suit formal and business settings.

Build Integration

A leather strap with a buckle clasp secures the watch to the wrist without tools. Sapphire crystal protects the dial from scratches during daily wear. Water resistance to 50 m handles splashes and brief immersion but is not intended for swimming or diving. The fixed bezel and analog display keep the profile slim under a shirt cuff.

Sustained Behaviour

Automatic movement delivers continuous operation as long as the watch is worn regularly; it stores enough energy to run through a night off the wrist. The day and date complication advances at midnight without manual adjustment for months of 31 days. Sapphire crystal maintains clarity over years of contact with clothing and surfaces.
