Open Heart Automatic Movement

This Citizen men's watch runs on an automatic mechanical movement visible through the open heart dial. The 40 mm stainless steel case houses a blue dial with Roman numeral markers. A genuine leather strap secures with a traditional buckle. The watch is supplied new and ready to wear.

Sapphire Crystal and 50 m Water Resistance

Sapphire crystal protects the analog display from scratches during daily use. The fixed bezel and pull-push crown maintain the 50 m water resistance rating suitable for splashes and brief immersion. Stainless steel construction handles casual wear without adding bulk to the wrist.

Slim 10.70 mm Profile for Comfort

At 10.70 mm thick the case slides easily under shirt cuffs. The automatic movement requires no battery changes, drawing energy from natural wrist motion. Leather band material breathes in warm conditions while the sapphire crystal resists heat buildup. Water resistance remains effective through normal temperature shifts.

Questions about this item

How long will the automatic movement run once I stop wearing it?

The automatic movement keeps running while worn; if left off the wrist it will stop after its power reserve is depleted, so occasional wrist time keeps it ticking.

Does the sapphire crystal and 10.70 mm case thickness make the watch feel hot or heavy during all-day wear?

The 40.00 mm stainless-steel case and 10.70 mm profile sit close to the wrist, and sapphire crystal does not generate heat, so the watch stays comfortable for extended daily use.

What strap width does the 40 mm case accept if I want to swap the leather band?

The 40 mm case uses a standard lug width that matches the supplied leather strap, so any compatible strap with the same lug spacing can be fitted.
