SANDAHL AEREUS
BUILT TO EVOLVE
A bronze watch with a character that develops through wear.
AEREUS is a collection of 40 mm automatic dive watches designed in Sweden and crafted in CuSn8 bronze. Inspired by the Nordic archipelago, it pairs rich dial colours with a metal that develops its own patina over time. The construction includes sapphire crystal and 200 m water resistance.

CHARACTER, SHAPED BY TIME
Bronze responds to its surroundings. As the surface gradually develops a patina, AEREUS acquires a character shaped by the way it is worn.
- 40 mm CuSn8 bronze case

SANDAHL WATCHES
crafted in detail
AEREUS brings together the warmth of bronze, the depth of colour and the clarity of a dive-watch dial — details designed to gain character over time.

case
The 40 mm CuSn8 bronze case gives AEREUS its warmth and distinctive presence. Brushed surfaces and a bronze dive bezel emphasise the material, which gradually develops a patina through wear and exposure. The underlying geometry stays consistent as each watch takes on a surface character of its own.

dial
Manufactured in-house in Sweden, each AEREUS dial contrasts with the surrounding bronze. Rich colour adds depth, while luminous hands and hour markers keep the layout clear. Restrained typography and the SANDAHL trident complete a composition inspired by the collection's coastal setting.

crown
The screw-down bronze crown carries the engraved SANDAHL trident and provides a defined grip for setting and winding. Its proportions complement the case, making it an integral part of the design. As the bronze develops its patina, this functional detail evolves with the watch around it.

colour
AEREUS pairs cool, water-inspired dial colours with the warm tones of CuSn8 bronze. Four expressions share the same proportions and materials, each offering a different balance of contrast and depth. As the case develops a patina, the relationship between dial and metal continues to change.
LUMISAND — MADE IN NYNÄSHAMN
WHEN THE LIGHT FADES
As daylight fades, another side of SANDAHL comes to light. LumiSand is our own luminescent compound, made in-house in our workshop in Nynäshamn, Sweden. It brings our approach to craftsmanship into the details you see after dark.

CHARGED BY LIGHT
LumiSand absorbs light and releases it as a glow in darker surroundings. Its brightness gradually fades, with the intensity and duration influenced by the light exposure before use.

CRAFTED TO GLOW
From the colour of a dial to its expression after dark, every detail contributes to the character of a SANDAHL watch. Making LumiSand in our own workshop brings a personal part of our craft to that transformation.

MECHANICAL AT HEART
THE MECHANICS OF AEREUS
SANDAHL Calibre SC200 gives AEREUS its automatic mechanical heart. Wound by the motion of your wrist, the movement brings a continuous mechanical rhythm to a watch whose bronze exterior evolves with wear.
Each movement is modified and finished in-house in our workshop in Nynäshamn, Sweden, with SANDAHL rotor detailing and engraving. The watches are also assembled here, bringing the movement, locally made dial and bronze case together.
Established engineering and individual finishing give the collection a mechanical identity to match the character of its materials.
