Expression of Elements

PROMASTER CHRONOGRAPH

https://ms.citizen.jp/assets/051_06-09_E210_01

At the heart of this model lies the distinctive 'multi-function' as its core 'element.' How these 'elements' have been expressed from a design perspective is reflected in the high level of completion of this watch. The unique configuration, such as displaying the charge level in a fan shape and using its center as the 12 o'clock index, is one of this model's attractions. At the same time, many elements are arranged on the dial and ring in layers and surfaces so that they do not interfere with each other. Rather than superficially expressing the word 'sports' in form, the design is carefully crafted, such as not adding unnecessary recessed or protruding structures, anticipating actual usage situations. The metal band features alternating polished finishes on the connecting links, creating a dynamic sense of individuality. Additionally, by finishing the crown and push button guards separately, the model is characterized, and together with the shape of the push buttons, it invites the user to utilize the chronograph functions. By structuring and expressing the 'elements' of 'function' and 'sports' with a focus on their essence, this model embodies the true spirit of PROMASTER.

Although the case is large at 44.0 mm, the full-flow integration with the band gives it a clean impression despite the abundance of information.

undefined

The total case thickness is 14.5 mm, but with the bezel, case body, and case back in a 3:5:2 ratio, it avoids feeling unnecessarily bulky.

undefined

The upper part of the case lugs is aligned with the upper surface of the band, further emphasizing the sense of unity between the case and the band.

By giving the 3 o'clock separate guard a different finish from the main body, the watch's functionality is expressed. The guards are designed to adjust the protrusion of the crown and push buttons so they do not cause stress on the wrist.

undefined

The 8 o'clock alarm crown, which is not used regularly, is covered by an integrated guard with a flowing line, reducing stress on the wrist.

undefined

The mirror-finished parts of the connecting links are arranged alternately inside and outside, providing an accent within the otherwise monotonous structure. The adoption of the H-link structure improves the fit on the wrist.

undefined

The center of the 12 o'clock charge level indicator hand also serves as a round luminescent index, making the charge display and the unique window shape the model's most distinctive features.

By making the bezel thin and less assertive, the functional information of the dial and ring is conveyed to the fullest extent.

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?
