Square Skeleton Automatic Watch – Sapphire Crystal

Men’s Square Skeleton Automatic Watch – Sapphire Crystal & 5 ATM

Discover mechanical watchmaking through a bold contemporary design with the Men’s Square Skeleton Automatic Watch.

Featuring an exposed mechanical dial, distinctive square case, sapphire crystal and luminous details, this timepiece combines visible mechanics with a modern sport-inspired aesthetic. Available with different strap and color combinations, it offers a striking alternative to the traditional round mechanical watch.

⚙️ Openwork Skeleton Mechanical Dial

The centerpiece of the watch is its intricate skeleton dial, exposing the mechanical architecture beneath the hands.

Visible gears and layered components give the dial remarkable depth, allowing the movement itself to become an essential part of the watch's design.

🔄 Automatic & Manual-Winding Mechanical Movement

The watch features a mechanical movement with automatic self-winding and manual-winding capability.

Natural wrist movement helps power the mechanism during wear, while manual winding provides an additional way to keep the movement running.

No conventional battery is required.

💎 Sapphire Crystal

The dial is protected by sapphire crystal, offering excellent scratch resistance and clarity for an unobstructed view of the skeleton movement.

This is an important upgrade for a mechanical watch designed to showcase its internal architecture.

🔲 Distinctive Square Case

The bold square stainless steel case gives the watch a contemporary appearance that immediately distinguishes it from conventional round mechanical watches.

According to the detailed dimensions, the case measures approximately 42 mm (1.7 in) wide × 48 mm long, with a 38 mm (1.5 in) dial opening and a relatively slim 11.7 mm (0.5 in) thickness.

The combination creates substantial wrist presence without excessive thickness.

✨ Luminous Display

Luminous elements improve visibility in low-light environments while creating a striking effect across the skeleton dial after dark.

The luminous version emphasizes the hands and hour markers against the intricate mechanical background.

🛡️ Stainless Steel Construction

The stainless steel case provides a solid foundation for the mechanical movement and contemporary square design.

Depending on the selected variant, the watch can be paired with different strap styles for either a sportier or more traditional appearance.

🤎 Multiple Strap & Color Options

The available variants shown for this model include:

Black • Blue • Brown • Brown Black

The product images show both leather-style straps and darker sport-style straps, allowing customers to choose between a classic or more contemporary appearance.

💧 5 ATM Water Resistance

Rated to 5 ATM / 50M, the watch provides enhanced protection against everyday water exposure compared with basic 3 ATM models.

It is suitable for everyday splashes and rain. To protect the mechanical movement and strap over the long term, avoid operating the crown while wet and avoid unnecessary prolonged immersion.
