The world is overflowing with products. Every year, countless new items are born and then disappear, shaped by the trends, lifestyles, and tastes of the moment. And yet, there are also products that people cherish and keep using with care for a long time. What sets apart things that soon vanish from those that become long-loved companions?

Precisely because we live in an age filled with distinctive products, this diver's watch was created with the aim of being a watch that people will value and keep using for a long time. In particular, we focused on expressing, through design, the “wearing comfort” that is crucial for a diver's watch and the “peace of mind” that makes you want to keep using it.

A softly contoured shape with minimal edges

The case and the register ring were given shapes with as few edges as possible to create a soft impression. This way, even if they bump into something, contact occurs over a surface rather than at a point or along a line, making the watch less prone to scratches and, above all, helping to avoid injuring whatever it comes into contact with—be it a person or an object. Since a diver's watch is often worn not only for diving but also for outdoor activities and sports, we believed such consideration would translate into a greater feeling of ease when wearing it. The result is a form that is comfortable to wear and minimizes stress.

One-piece construction

For the larger men's model, we have adopted a one-piece construction in which the case back is integrated with the case body to further enhance water resistance. Its ruggedness, evident at a glance, imparts a sense of assurance.

A watch that is gentle on the wearer and on the environment

For a diver's watch, water resistance is paramount. Because even a simple battery replacement calls for a water-resistance test, it's possible that when you're about to go diving, your watch has stopped and replacing the battery could take time. This model is equipped with CITIZEN’s light-powered Eco-Drive technology, so even if it has stopped, exposing the dial to sunlight for half a day is enough to recharge it. Eco-Drive is a feature that pairs exceptionally well with a diver's watch. As a diver's watch, it offers excellent usability, and because you never need to dispose of batteries that would become industrial waste, it’s gentle on both the wearer and the environment.

With everyday use in mind, its wrist-friendly, simple design—unaffected by passing trends—has earned lasting support, and since its release in 1998, it has been loved by users for many years. In 2012, it received the Good Design Long Life Design Award.

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.

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.

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.

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.
