Product Specifications

Stealth All-Black Design

Strong, Modern Wrist Presence

The black dial, bezel, case and bracelet create a unified stealth appearance that immediately separates this model from conventional silver stainless steel diver watches.

Despite its monochrome colour scheme, the contrasting luminous-style markers, hands and bezel markings help keep the watch visually clear and easy to read.

Professional Diver-Style Dial

High-Visibility Markers

Large circular and rectangular hour markers are arranged around the dial with substantial luminous-style inserts. The broad hour and minute hands follow the same high-visibility design language.

A distinctive 12 o'clock marker creates an immediate reference point, while the clean minute track around the edge gives the dial a functional tool-watch appearance.

Automatic Mechanical Movement

Traditional Mechanical Operation

The dial identifies this model as an automatic mechanical watch. Automatic movements use mechanical energy and the motion of the wearer rather than the conventional battery system found in standard quartz watches.

The dial also carries an “Automatic 3 Days” marking. The exact movement caliber and tested power-reserve duration should be confirmed against the specification of the supplied watch.

Black Diver-Style Bezel

Functional Tool-Watch Character

A black rotating diver-style bezel surrounds the dial and features large contrasting numerals and minute markers.

The white bezel markings provide strong contrast against the black background while reinforcing the professional diving-watch aesthetic.

Practical Date Display

A date window is positioned near the 3 o'clock area. The white date background contrasts sharply against the black dial, making the calendar display easy to identify at a glance.

4 O'Clock Crown Position

The crown is positioned around the 4 o'clock area rather than directly at 3 o'clock. This placement gives the case its distinctive diver-style silhouette and helps integrate the crown more naturally into the overall design.

Black Metal Bracelet

Integrated Sport-Watch Appearance

The matching black link bracelet continues the stealth finish from the case and bezel through to the wrist. Its broad links complement the substantial case and help create a solid, premium appearance.

Adjustable Fit

Link-style bracelets can generally be resized by removing links, allowing the watch to be adjusted according to wrist size. Professional adjustment is recommended.
