39.7mm Japanese Automatic Dive Watch – Sapphire Crystal, AR Coating & 200M

🌊 A professional-inspired automatic sports watch combining Japanese mechanical engineering, sapphire crystal and serious 200 m water resistance.

Designed for everyday wear as well as aquatic activities, this Japanese Automatic Dive Watch features a Japanese mechanical movement, robust 316L stainless steel construction, a screw-down crown and 20 BAR / 200 m (656 ft) water resistance.

Its clean black dial, bold Arabic numerals and highly legible minute markings give it a distinctive pilot-meets-diver aesthetic, while sapphire crystal with anti-reflective coating provides premium protection and excellent visibility.

🇯🇵 Japanese Automatic Mechanical Movement

At the heart of the watch is a Japanese mechanical movement combining automatic self-winding and manual winding.

Movement of your wrist helps keep the mainspring wound during normal wear, while the crown can also be used for manual winding when necessary.

No battery is required to power the mechanical movement.

🌊 20 BAR / 200M Water Resistance

With a rated water resistance of 20 BAR / 200 m (656 ft), this watch is built for significantly more demanding water exposure than a typical everyday watch.

Its construction includes a screw-down crown, an essential feature for maintaining the case's water-resistant seal.

Suitable for everyday water exposure, swimming and snorkeling. For diving use, the seals and water resistance should be periodically pressure-tested.

👑 Screw-Down Crown

The screw-down crown helps reinforce the watch's water resistance by creating a tighter seal against the case.

Always make sure the crown is completely screwed down before contact with water.

💎 Sapphire Crystal

The dial is protected by sapphire crystal, valued for its exceptional resistance to scratches during normal wear.

This provides significantly better long-term scratch resistance than conventional mineral or acrylic watch crystals.

☀️ Anti-Reflective Coating

An AR (anti-reflective) coating helps reduce distracting reflections from the crystal and improves dial readability under bright lighting.

Combined with sapphire crystal, it gives the watch a premium specification particularly suited to outdoor and professional-style use.

🛡️ 316L Stainless Steel Construction

The case and bracelet use durable 316L stainless steel, providing excellent resistance to everyday wear and corrosion.

The solid steel construction also gives the watch a substantial presence, with an approximate weight of 144 g (5.08 oz).

🔢 High-Legibility Arabic Numeral Dial

The black dial uses oversized Arabic numerals at 3, 6 and 9 o'clock, combined with prominent minute markings around the dial.

The result is a clean, instrument-inspired layout designed to make the time easy to read at a glance.

✨ Luminous Hands & Markers

Luminous elements improve readability when moving from bright environments into lower-light conditions.

After sufficient exposure to light, the luminous material provides temporary visibility in darkness.

🔗 Stainless Steel Bracelet

The 20 mm (0.79 in) stainless steel bracelet complements the robust case while maintaining a versatile appearance suitable for business, casual and sportswear.

A folding clasp with safety helps keep the watch securely positioned on the wrist.

📐 Balanced 39.7mm Case

At approximately 39.7 mm (1.56 in) in diameter, the watch avoids the oversized dimensions of many modern dive watches.

Its 12 mm (0.47 in) case thickness maintains a substantial mechanical presence without becoming excessively bulky.
