Citizen - Automatic NH9130-17A Mens Watch Calf Leather Strap Open Heart 50M - Ivory Dial

The Citizen NH9130-17A is a sophisticated "Open Heart" mechanical watch. It belongs to Citizen’s collection of accessible automatic timepieces, offering a classic dress watch aesthetic with a mechanical twist.

• Movement: Automatic Caliber 8229 (Self-winding + Hand-winding)
• The "Open Heart": The defining feature is a circular cutout at the 7 o'clock position, allowing you to see the balance wheel—the beating heart of the mechanical movement—in motion.
• Exhibition Case Back: The back of the watch is transparent (mineral glass), letting you view the rotor and gears from the underside.
• Premium Materials: For its price point, the inclusion of a Sapphire crystal is a major advantage, as it is much harder to scratch than the mineral glass found on many other entry-level automatics.
• Modern Classic Size: At 40mm, it hits the "sweet spot" for modern dress watches—large enough to have presence but slim enough to slide under a shirt cuff.
