Japanese Automatic Diamond Watch – Sapphire Crystal & Tungsten Steel Bracelet

Discover a distinctive automatic timepiece combining Japanese mechanical engineering, a deep celestial-style dial, sparkling stone-set detailing and a premium tungsten steel bracelet.

Its 40 mm case offers a classic, wearable profile, while the dark textured dial, Roman numeral accents and gold-tone hands create an elegant contrast. Protected by synthetic sapphire crystal and rated to 5 ATM / 50 m (164 ft), it combines refined styling with practical everyday durability.

💎 Sparkling Stone-Set Design

The perimeter of the dial is surrounded by brilliant decorative stones that give the watch a distinctive jewelry-inspired appearance without overwhelming its classic design.

Combined with the celestial-textured dial and polished metallic details, the result is particularly striking under changing light.

⚙️ Japanese Automatic Mechanical Movement

At its heart is a Japanese automatic self-winding mechanical movement.

The movement is powered by the motion of the wrist during wear, eliminating the need for a conventional quartz battery.

🌌 Celestial-Inspired Dial

The textured dark dial creates a starry, night-sky appearance, complemented by elegant hands, Roman numeral details and a discreet date window at 6 o'clock.

Luminous elements improve visibility in darker environments.

💎 Synthetic Sapphire Crystal

The dial is protected by synthetic sapphire crystal, offering excellent scratch resistance and long-lasting clarity compared with standard mineral glass.

🔗 Tungsten Steel Bracelet

A distinctive tungsten steel bracelet gives the watch a substantial, premium feel on the wrist.

The bracelet measures approximately 20 cm (7.87 in) in circumference and uses a secure butterfly-style clasp.

💧 5 ATM Water Resistance

With 5 ATM / 50 m / 164 ft water resistance, the watch is designed to handle normal daily exposure to water.

I would avoid marketing it specifically as a diving watch, despite the supplier's “DIVER” attribute. A 5 ATM rating is not appropriate for diving.
