Men’s Automatic Open-Heart Watch – Multi-Calendar & Stainless Steel

Discover a mechanical watch that combines classic styling, visible mechanics and an unusually detailed calendar display.

This automatic timepiece features an elegant multi-layer dial with Roman numeral hour markers, day and date subdials, year/month display, and an open-heart window revealing the mechanical movement in action.

Finished with a polished stainless steel case and bracelet, it creates a sophisticated statement piece for business, formal occasions and everyday wear.

⚙️ Open-Heart Mechanical Display

The highlight of the dial is the exposed mechanical section at 6 o’clock.

Rather than hiding the movement completely behind the dial, the open-heart design reveals the oscillating mechanical components, bringing motion and depth to the watch face.

It gives the watch the visual appeal of skeleton watchmaking while retaining a refined, structured dial.

📅 Multi-Calendar Dial

The dial combines several calendar indications into one distinctive layout:

• Day-of-the-week subdial
• Date subdial
• Year display
• Month display
• Analog hour, minute and second hands

The combination creates a highly detailed mechanical aesthetic while making the calendar one of the defining visual elements of the watch.

✨ Detailed Multi-Layer Dial

Roman numerals, textured subdials, polished hands and crystal-style hour accents create a sophisticated appearance from every angle.

The concentric dial textures add depth, while the exposed mechanical section contrasts beautifully with the more traditional calendar displays.

🌙 Luminous Hands

Luminous material on the hands helps improve visibility in darker environments after exposure to light.

This subtle nighttime glow complements the watch's elegant mechanical design without overwhelming the dial.

🔄 Automatic & Hand-Winding Mechanical Movement

The mechanical movement can be powered through the natural motion of your wrist during regular wear.

Manual winding is also supported, allowing the movement to be restarted or powered when the watch has not been worn for a period of time.

No battery is required.

🔩 Stainless Steel Construction

Both the case and bracelet are made from stainless steel, giving the watch a substantial appearance while providing durability for everyday wear.

The polished multi-link bracelet complements the detailed dial and reinforces its classic business-watch character.

💎 Hardlex Crystal

The dial is protected by Hardlex mineral glass, providing good clarity and resistance against normal everyday wear.

💧 3 ATM Water Resistance

Rated to 3 ATM, the watch is suitable for everyday exposure such as light rain and occasional splashes.

Avoid swimming, showering, diving, hot water and steam.
