Released in March 2025. 300 pieces made. Now discontinued.
Anoma creates wearable sculptures, inspired by the rich world beyond watchmaking. We draw inspiration from art, architecture, nature, and beyond, to craft designs that feel both strikingly new and deeply familiar.
We believe true beauty whispers, it doesn’t shout. With the A1 Slate, we set out to create the purest, most distilled expression of the A1 — an exercise in reductive design, where elements are stripped away to reveal the essence of an idea.
The dial begins with a vertically brushed base, followed by the engraving of contrasting triangles. Finally, three layers of black lacquer are applied on top. This creates a surface that shifts between smooth gloss and sharp two-tone contrast, inviting continual rediscovery.

Our Inspiration

The watch's rounded triangular shape was inspired by a 1950s free form table by Charlotte Perriand. We first came across one in a Parisian antique gallery a few years ago.

We were also inspired by the organic softness of river stones, valued for their tactile and inherently pleasing nature.

The modernist sculptures of Constantin Brancusi deeply influenced us, particularly in their ability to convey movement and create tension by contrasting thick and thin sections.

“It was love at first sight. On the wrist, it embodies a piece of art awaiting attraction and admiration.”
Roni Madhvani – Collector

Sculptural Form
The case combines two overlapping triangles, deliberately offset to create a sense of movement and tension between thick and thin sections.
To focus on the purity of the forms, we concealed any distractions by hiding the lugs, crown, and any other superfluous details.

Layered Dial
The dial invites continual rediscovery and subtle appreciation. Its vertical brushing, contrasting engraved triangles, and triple-layer black lacquer create a dynamic play of smooth gloss and sharp two-tone contrast.

Subtle Details
To preserve the sculptural feel of the watch, the strap integrates directly into the case, through two slender openings on either side.
The crown is also recessed into the case, helping to maintain a sleek and uninterrupted silhouette from most angles. An aperture at the back makes it easy to access and operate the crown.

“The A1 is a breakthrough and unconventional piece made by someone who not only knows watches, but also has a deep knowledge and love for them.”
Alex Ghotbi — Collector, Head of Europe and Middle East at Phillips Watches
How does it wear?
The A1 was carefully designed to be as comfortable as possible, on all kinds of wrists. The case measures 39mm by 39mm, but it wears closer to 37mm, thanks to its triangular shape, lack of lugs and hidden crown.
The case is 9.45mm thick, but the bottom 3mm curve inwards, allowing them to disappear into the wrist when the watch is worn. This makes the A1 wear even thinner than its dimensions would suggest.
Due to the soft, rounded profile of the case and the wrist bone holding the watch in place, the tip of the triangle at 3 o’clock does not cause any discomfort.
The circumference of the wrist in photography is 16.5cm (6.5 inches).
