Concept

“When you go to the limit of nothingness,
something beyond human knowledge is born”
MONOLITH is a wristwatch supervised by architect Katsufumi Kubota,
who is active in Japan and abroad as a pioneer of minimalism.
Every time you behold that refined presence,
your heart feels deeply fulfilled.

The minimalism I aimed for in <MONOLITH> is not merely about eliminating excess to achieve simplicity. The great architectural masterpieces I have visited evoke a sense of calm and vitality when I immerse myself in their minimal spaces. Particularly in traditional Japanese architecture, which can be described as simple, there is a beauty that harmonizes the human spirit with nature. I believe that is the true power of minimalism.
Through these experiences, what I have cultivated as an architect can also be applied to watch design. When one reaches a state of emptiness, something beyond human understanding is born. I aspire for <MONOLITH> to be an object that invigorates the spirit every time it catches the eye. I believe this can be a catalyst for a richer life.
The ancient Roman architect Vitruvius stated in his work "De Architectura" that making a clock is a task for architects. This was because sundials of that time could only be created by architects well-versed in mathematics, structure, and the natural sciences. This is where my desire to design watches originated.

Case

Created

Gunma Instrument Inc.

The beautiful titanium body of MONOLITH combines simplicity with strength. It is crafted through the technical prowess of Gunma Instrument Inc. a manufacturer of global brand watches. The creation of the initial high-quality mold for the case manufacturing process relies not only on cutting-edge machinery but also on the exceptional skill and uncompromising attitude of the people involved.
The basic shape formed by the mold undergoes multiple forging and pressing processes to create the final case shape. The surface finishing and painting processes are all carried out by skilled artisans by hand.

Watch Straps

Created

jean rousseau

The rubber-coated leather strap with a D buckle is crafted by Jean Rousseau, known for its meticulous finishing using carefully selected leather since its founding in 1954. With its own tanning facilities, Jean Rousseau operates flagship stores in Paris, London, Tokyo, and New York, producing a variety of leather goods, including watch straps. Their exceptional craftsmanship, elegance, high quality, and dedication to preserving and promoting traditional techniques have earned Jean Rousseau the designation of "Intangible Cultural Heritage Company" from the French government in 2007.

Movement

Automatic [self-winding] watch

Created

miyota

The movement that powers MONOLITH is made by MIYOTA, which has supplied watch movements to brands around the world for 40 years. MIYOTA's origins date back to 1959 when Citizen Watch Co., Ltd. established a movement manufacturing factory in Miyota Town, Nagano Prefecture. Since then, they have continuously supplied new products to the market through relentless development.
"To provide quality watches to as many people as possible," MIYOTA continues to offer enduring value that transcends generations.

Glass

Sapphire Glass

Materials

Sapphire Glass

The crystal protecting the dial of MONOLITH is made of sapphire glass. To enhance the matte black of the dial, the sapphire glass features an anti-reflective coating on both sides, with an additional fingerprint-resistant coating on the top surface. The case back is also treated with an anti-reflective coating and has a gray vapor deposition that blends the metal's sheen, giving an elegant expression to the movement.
Sapphire glass possesses excellent optical, thermal, mechanical, and electrical properties, and is well-known as the second hardest mineral after diamond. It is highly resistant to scratches, even in harsh environments where sand and other abrasive materials may be present.

Dial

Matte Black

Muonionalusta

Materials

Matte Black or Meteorite

To express the world of MONOLITH, we have applied a deep black matte finish that eliminates all gloss. To achieve this black, we meticulously focused on the depth, luster, and shading of the color through multiple iterations, balancing practicality while pushing the limits of how dark we could make it. Covered with a highly porous surface that has a high light absorption rate, we have achieved a pure black reminiscent of outer space. The special coating is so sensitive that even a brief touch can render it unusable.
Additionally, we are planning an IP Black plated model featuring meteorite (the Muonionalusta, discovered in 1906).

Hands

Luminescence

Materials

LumiNova

The hands of MONOLITH feature N Night Glow (Luminova)®, developed by Nemoto & Co., Ltd.
N Night Glow (Luminova)® is brighter than traditional luminescent paints and glows longer than fluorescent paints. This luminescent pigment exhibits high brightness and long afterglow when exposed to natural light or fluorescent light. It also boasts excellent light resistance, ensuring stable use over an extended period.
To emphasize the shape of the hands and ensure visibility, the luminescent paint is applied to the top surface using silk screen printing. The hands floating on the dial in the dark combine beauty with practicality.
