PROMASTER PROFESSIONAL DIVER 1000m

This diver's watch is a model that took on the challenge of how to give an attractive design to a core that is engineered to withstand depths of 1,000 meters and reliably function in such harsh environments. In other words, the major challenge was how to use design to bring together the 'stacked box structure and form'—resulting from the addition of a bezel misoperation prevention mechanism to a case that must already be thick to withstand high depths.

When viewed from the side, the use of polished and matte finishes ensures that the eye does not focus on any one area, and the insertion of black components prevents the watch from appearing as a thick mass. Additionally, by making the outer circumference of the bezel a slope that spreads downward and the underside a reverse slope, the watch avoids looking like a rugged metal block and instead gives an organic, almost sea creature-like impression, reminiscent of a turban shell or sea anemone. This is a good example of design and function fusing together, giving a diver's watch a marine organism-inspired appearance.

By rotating the ring outside the bezel, the locking mechanism is engaged to prevent accidental rotation of the bezel. When the lock is released, orange can be seen from beneath the component, allowing users to visually confirm whether the mechanism is engaged.

undefined

Each component is layered according to its function, resulting in a shape and structure that is easy to handle even when wearing gloves.

undefined

Although the overlapping components make the watch thick, each part is given a slope to prevent unnecessary snagging or damage. The hard shapes are complemented by slopes and curved surfaces, giving it a marine organism-like feel.

undefined

A subtle, large curve is applied to the entire surface, and a mark created by coining is placed at the center of the luxurious case back, giving it a professional-use feel.

undefined

The dial uses molded recesses, protrusions, and patterns to create details that rival those of the case.

undefined

Black resin is placed around the mark and polished to be flush with the mark.

undefined

Resin is inserted at the base of the crown, and if the crown is not properly screwed into the case, the resin color becomes visible. Like the bezel lock, this specification ensures that the status of life-critical components is always managed.

A hard, voluminous titanium buckle that matches the robust case.

The charge level is indicated by a gradient created with dot printing.

Retro Future

In the 1970s, a new method of time display—digital display—was developed. At the time, this display function evoked expectations for watches of the near future. This watch was designed based on the idea of utilizing the effectiveness of digital display and, for the first time, adding a calculator function to a wristwatch. The first domestically produced wristwatch to combine watch and calculator functions is expressed with a unique design style: a central display monitor and 23 push buttons arranged radially around the perimeter. Achieving this in the classic round shape of a wristwatch is a testament to the creativity of watch designers. The artificial brilliance of the push buttons, arranged every 15 degrees. The simple lines of the case and band, free from any recesses or protrusions. These are the result of traditional machining, and the combination of a thick case and cool digital display creates a retro-futuristic feel through the imbalance of old and new technologies. Additionally, this early model is unified in gold, skillfully using gold with different textures for each exterior part, creating an elegant atmosphere despite the flashy color scheme. Although the distinctive button layout did not become standard, it exudes the coolness and pride of being a pioneer.

Feeling Light

Urushi beads, diamonds, and smoked glass—each reflects light differently, revealing a model with depth and ever-changing expressions depending on the light source and time of day. The simplicity of the case shape and dial design highlights the beauty of the details, allowing you to sense not mechanical time, but the gentle passage of time illuminated by light. Although there are no indexes on the dial, the hour and minute hands are easy to read, giving the impression of a bracelet that also functions as a watch. Furthermore, urushi lacquer is not presented in the traditional way, but is fused with the watch in a modern design, letting you enjoy a contemporary expression of traditional craftsmanship. Despite its asymmetrical shape, it is comfortable to wear and offers a special feeling, as if wearing modern jewelry.

Vitality of Nature

Many CITIZEN L models are inspired by shapes and light found in nature, and this model is themed around 'morning dew.' The three diamonds on the case move smoothly along the curve of the case, and the indexes are scattered across the dial, creating a story that evokes scenes from nature even for those who know nothing about the watch. Looking at the parts, despite the many asymmetrical elements—such as the dial pattern, index arrangement, crown position, and case shape—each is balanced in its placement, so there is no sense of discomfort or difficulty in wearing it. The asymmetrical design brings a rhythm and movement reminiscent of the vitality of nature, making you feel a relaxed, natural flow of time rather than a uniform one. Although the watch uses many diamonds and has a jewelry-like feel, the arrangement of the indexes and the spacing between the case and band give it an airy look, making it suitable for everyday wear as well.

From Small Cues to Decoration

"Band, hands, circle"—these are the minimal components by which people recognize a watch. ◆ A watch is a "wrist" watch because it has a band. ◆ A watch is a watch because it has hands. ◆ Time was created from the recurring cycles (circles) of celestial bodies. This model seems to be a textbook example of a "watch" that focuses on these three elements. By lavishly decorating these three elements, it clearly establishes the hierarchy among the other components. Isn’t this the ideal model for all watches, combining the "watch-like" qualities users seek with the beauty of an ornament that satisfies them?
