Moon Phase Automatic Watch – Power Reserve, Sapphire Crystal & Date

Experience traditional mechanical watchmaking with a sophisticated multi-function dial. The Moon Phase Automatic Watch combines an automatic mechanical movement with a moon phase display, power reserve indicator and date display, all protected beneath a sapphire crystal.

Its 41 mm stainless steel case and genuine leather strap create an elegant profile suitable for business wear, formal occasions and everyday use.

🌙 Moon Phase Display

One of the most distinctive elements of the dial is the moon phase display positioned around 2–3 o'clock.

This mechanical complication visually tracks the progression of the lunar cycle while adding depth and character to the dial. The contrasting moon and night-sky design creates an elegant focal point without overwhelming the overall appearance of the watch.

⚡ Power Reserve Indicator

The fan-shaped indicator around 9–10 o'clock displays the remaining mechanical energy available to the movement.

Instead of guessing when the watch may need additional winding, the power reserve indicator provides a convenient visual reference directly on the dial.

A fully wound movement provides approximately 35–40 hours of power reserve, depending on use and winding conditions.

📅 Analog Date Display

A dedicated subdial at 6 o'clock provides an elegant analog date display.

The circular scale complements the mechanical character of the watch while allowing the date to be integrated directly into the dial rather than using a conventional rectangular date window.

⚙️ ST2153 Automatic Mechanical Movement

At the heart of the watch is the ST2153 automatic mechanical movement, operating without a disposable battery.

The movement is powered naturally by wrist motion during wear and can also be manually wound through the crown when additional power is required.

Movement specifications include:

• Automatic self-winding mechanical movement
• Manual winding capability
• Approximately 35–40 hours power reserve
• 28,800 vibrations per hour
• 32 jewels
• Manufacturer-stated accuracy of approximately ±20 seconds per day

For the first use, manually winding the watch is recommended before relying on automatic wrist movement.

🔍 Exhibition Case Back

The transparent case back reveals the mechanical movement inside the watch.

The oscillating rotor, bridges and internal components remain visible while the watch is operating, providing a direct view of the mechanical engineering powering the timepiece.

💎 Sapphire Crystal

The dial is protected by sapphire crystal, valued in watchmaking for its excellent resistance to everyday scratches.

It provides a clear view of the detailed multi-layer dial while offering greater scratch resistance than conventional mineral glass.

✨ Stainless Steel Case

The watch features a polished stainless steel case designed to complement its sophisticated mechanical dial.

With a diameter of approximately 41 mm (1.61 in), it provides substantial wrist presence while remaining suitable for business and dress wear.

The case measures approximately 11.5 mm (0.45 in) thick.

🐄 Genuine Leather Strap

A genuine leather strap complements the traditional mechanical design.

Its textured finish gives the watch a refined appearance while remaining versatile enough for professional, formal and smart-casual outfits.

The strap measures approximately 21–23 cm (8.27–9.06 in) depending on the configuration and adjustment.

💧 5 ATM Water Resistance

The watch offers water resistance rated to 5 ATM / 50 m (164 ft).

It is designed to withstand normal everyday exposure such as rain and accidental splashes.

To preserve the watch and leather strap, swimming, showering, bathing and diving are not recommended.
