Simple yet Distinctive

PROMASTER is a brand for professionals on land, at sea, and in the air. In particular, diver's watches, which are designed for sea professionals, must meet strict standards set by ISO 6425, including high water resistance, a unidirectional bezel, visibility in the dark, and shock resistance. The product introduced here was born from the family model project of the 'PROMASTER AQUALAND 200m,' which was released last year to great acclaim. While inheriting the case lines and rotating bezel design, this ISO-compliant 200m water-resistant diver's watch adds new value with a GMT function and titanium material. In addition to the PROMASTER mission of functionality, durability, and safety, the watch was developed with a focus on the visibility and operability most needed in a diver's watch, and it won the Good Design Award in 2019.

Simplicity in Many Functions

The PROMASTER AQUALAND is a diver's watch series equipped with a depth gauge. Under the concept of creating a diver's watch that embodies both the 'inheritance' and 'evolution' of AQUALAND, we revisited the fundamental concept of PROMASTER and developed a genuine diver's watch that expresses many functions in a simple way. In a broad market where minimal designer watches and impact-focused designs coexist, this model can be called a new standard, thoroughly pursuing functionality, durability, and safety to withstand harsh environments. Its high functionality and design have been recognized, earning it the Good Design Award in 2018.

The Essential Role of a Watch

A watch, as its name suggests, is an instrument that marks the passage of time. This model focuses on how to make that time as easy to read and as beautiful as possible. Not only are the shapes and finishes of the hands and indexes, and the large, highly legible date display carefully considered, but the case and bezel are also composed of multiple surfaces that are skillfully combined. This results in a beautiful finish from any angle, thanks to the way they reflect light. In the case of a three-hand layout, which can often appear monotonous, the power reserve indicator positioned at 10 o'clock adds a distinctive touch and expresses individuality. The symbolic emblem on the case back provides a sense of satisfaction to the wearer, while the case size and the way the lugs are shaped ensure a comfortable fit on the wrist. The design fulfills the essential role of a watch worthy of the name The CITIZEN. Elegant and refined, this is a timepiece exuding luxury.

Rhythm in Flow or Streamlined

The design offers a high level of comfort both visually and physically when worn on the wrist. The lines flow seamlessly from the band to the case. However, this does not end in a monotonous rhythm. When the flow reaches the case, the tempo suddenly changes. This ensures that the design does not simply end as a full-flow form, but also firmly expresses the presence of the case. Looking at the overall finish, only the sides are given a polished finish, while the center section, which occupies a large area, features a hairline finish running from 12 to 6 o'clock. This brings out the full appeal of the stainless steel material. Turning to the dial, its silver tone closely matches that of the case and band, which is a major characteristic of this model. By unifying the dial, case, and band in color, the flowing design is further emphasized. The markings on the dial are also printed in white, reflecting a commitment to a consistent tone. Not only the form, but also the color scheme, designed with a sense of flow in mind, is a major attraction.

The Richness

This watch boasts a wide array of functions, resulting in a high-density dial. The well-balanced arrangement of each element allows a wealth of information to be conveyed to the user in a clear and parallel manner. Additionally, the shapes and color schemes of the sub-dials are carefully considered for visibility, and together with the sense of compactness unique to multifunctional models, they visually delight the user. The case is composed mainly of taut curves with few flat surfaces, evoking the maternal fullness of earth goddesses found in many ancient civilizations, symbolizing abundance. The unexpected individuality of this model lies in its evocation of maternal qualities within the highly masculine genre of pilot watches. Rather than simply designing for functionality, the overall presence—from the dial layout to the case shape—aims to evoke a universal image of fundamental richness that resonates with everyone.

Uncompromising Craftsmanship

Every single part, from its shape to its finish, is crafted with meticulous attention, making this a masterpiece where you can sense the artisan’s dedication in every detail. The shape and cut of the indexes, the unique design of the day window frame, the magnifying lens over the date display, the font and layout of the logo and mark, the width and length of the minute track printing, the parting line between the case and bezel, the way the surfaces are finished, the box-shaped glass—there is not a single aspect where any compromise can be found. When all these elements come together to form a complete watch, each part harmonizes without overpowering the others. The result is a piece that is both striking and individual, yet exudes an indescribable elegance. This is truly the work of a master craftsman.

Inspire

The striking impact of the asymmetrical silhouette stirs an irresistible urge to pick it up. The prominently placed depth gauge on the dial and the sensor at the 9 o’clock position spark the imagination—what if you actually dove into the sea?—and ultimately ignite a genuine desire to own it. This model not only stimulates such subconscious feelings in users, but also possesses the functionality to fully satisfy those emotions. As with any product, not just watches, if you pursue functionality alone, you risk ending up with something bland and lacking in character. This model, however, brilliantly balances functionality with an iconic appearance, even within the constraints of ISO/JIS standards and underwater visibility requirements. As its nickname "Mola Mola Diver" suggests, the model features a silhouette so distinctive that it can be recognized at a glance, yet it never compromises on the functions required of a diver's watch. It truly embodies the designer’s essential role: achieving both practicality and a uniquely attractive appearance.

Visibility

For diver's watches used in life-critical diving situations, not only water resistance but also 'visibility' is considered essential. This model is equipped with the world's first electronic depth meter function. In addition to measuring the current and maximum depth, it also features an alarm function that is easy to hear underwater. However, the most important information is still the dive time. The deeper you go, the more your judgment declines, so this model pursues instant readability of the hands, carefully considering the size, shape, and luminescence area of the indexes and hands. It is truly a pioneering model that could be called the "bible of diver's watches."
