Automatic Mechanical Movement

Mechanical Performance Without a Conventional Quartz Battery

At the heart of the watch is an automatic mechanical movement. Normal wrist motion helps wind the movement and store mechanical energy, eliminating the conventional battery used by standard quartz watches.

If the watch is left unused long enough for its stored energy to run down, it may stop. Simply restart the movement and reset the time before wearing.

Open Heart Mechanical Display

Watch the Movement Come to Life

The open-heart section positioned at 6 o'clock reveals part of the moving mechanical assembly beneath the dial. Rather than hiding the movement completely inside the case, this design turns the mechanics of the watch into one of its main visual features.

The exposed balance mechanism adds continuous motion to the dial and makes the watch particularly attractive for mechanical-watch enthusiasts.

Elegant White Dial

Classic Design with Modern Detail

The bright white dial provides a clean foundation for the warm metallic hands, applied markers and Roman numeral accents. Fine dial detailing adds texture without making the face appear overly busy.

A large Roman numeral XII anchors the top of the dial, while Roman numerals at the lower positions create a distinctive dress-watch character.

Moonphase-Style Upper Display

A blue moon-and-stars detail positioned beneath the 12 o'clock marker creates a striking contrast against the white dial and warm metallic elements.

This feature should be marketed as a moonphase-style or day/night display unless the exact mechanical movement has been verified as containing a true astronomical moonphase complication.

Symmetrical Dual Subdial Design

Two circular subdials positioned on either side of the central hands give the watch a balanced and sophisticated appearance. Their fine concentric detailing complements the mechanical styling of the open-heart section.

Brown Crocodile-Pattern Strap

Classic Dress-Watch Styling

The brown leather-style strap features a crocodile-inspired embossed pattern and tonal stitching. It provides a traditional finish that pairs naturally with the warm metallic case and white dial.

The colour combination works particularly well with brown shoes and belts, formal suits, business attire and traditional outfits.

Designed for Special Occasions & Everyday Elegance

Business & Office

Pair the watch with a formal shirt, blazer or suit for a refined professional appearance.

Wedding & Formal Events

The open-heart mechanism, moon-and-stars detail and polished case give the watch enough presence for weddings, receptions, dinners and celebrations.

Traditional Wear

Its warm case and brown strap also complement panjabis, sherwanis and other traditional formal clothing.

Smart-Casual Wear

The watch can also be styled with shirts, polos and blazers when you want an everyday outfit to feel more sophisticated.

Frequently Asked Questions

Is this an automatic watch?

Yes. It features an automatic mechanical movement with a visible open-heart section on the dial.

Does this watch need a battery?

It does not use a conventional quartz battery. Its automatic mechanical movement is powered through stored mechanical energy.

What is the dial size?

Based on the supplied photograph, the case appears to be approximately 41–42 mm in diameter. Please verify the physical measurement before publishing an exact specification.

What is the case thickness?

The estimated case thickness is approximately 12–13 mm. Exact thickness should be confirmed using the physical product.

What is the open section at 6 o'clock?

It exposes part of the automatic mechanical movement, allowing the wearer to see the moving mechanism while the watch is operating.

Is the upper display a real moonphase?

The dial clearly features a moon-and-stars design. A true astronomical moonphase function should only be claimed if confirmed by the movement specification. Otherwise, it is best described as a moonphase-style or day/night display.

What type of strap does it have?

The photographed version features a brown crocodile-pattern leather or leather-style strap with a traditional pin buckle.

Can an automatic watch stop if I don't wear it?

Yes. Once its stored mechanical energy is depleted, an automatic watch may stop and need to be restarted and reset.

Is this watch waterproof?

The exact water-resistance rating cannot be verified from the photograph. Confirm the manufacturer's rating before making a specific waterproof or water-resistance claim.
