Studio Underd0g 04SERIES: three automatic watches with calendar complications reimagined

Studio Underd0g’s new 04SERIES collection solves a familiar watchmaking problem: fit multiple calendar functions on a dial without sacrificing legibility or proportion. The studio’s answer was to move the weekend indicator to a dedicated track around the dial’s perimeter, freeing the centre for a moonphase display and retrograde date pointer. The result is three new watches built around a customised Seagull automatic movement, the studio’s first in-house automatic calibre and two years’ work in the making.

The mechanical core matters here. Studio Underd0g specified thirty-four components of the Seagull calibre for this collection, redesigning the movement to power the new complication layout. A sapphire caseback reveals the finished mechanism, with applied jewels, on the reverse. This is the studio’s move into automatic horology, and the decision to customise rather than buy off the shelf tells you something about how the brand thinks: the movement is made visible and made personal.

Three dial colours, each with its own character. Cloud10 presents a soft sky blue with pink accents, the tonal family echoing across the retrograde date pointer and weekend track. Arabian Sky uses burnished gold with emerald green touches at the moonphase and weekend indicator. Shepherd’s Delight is a rich red dial with purple accents—unconventional territory in watchmaking, rooted in the old red-sky-at-night weather adage. Each pairing creates visual continuity without clutter; the complications read as part of the design rather than additions to it. Leather straps in matching tones anchor each variant.

Cloud10: Soft sky and rational precision

The Cloud10 shows a sky blue dial with soft pink accents, the colour chosen to capture that brief window before dusk deepens. The retrograde date pointer and weekend indicator are rendered in the same warm tone, creating a visual continuity that prevents the complications from reading as separate systems. The moonphase sits at six o’clock in conventional placement, but here it operates without the clutter that usually surrounds it. A brown leather strap anchors the palette. The name itself is a mild joke: the movement and dial construction pushed the team, by their own account, from cloud nine to cloud ten.

Arabian Sky: Burnished gold and emerald accents

Arabian Sky borrows its dial colour from the golden hour that crosses Arabian skies. The burnished gold surface is punctuated with emerald accents at the moonphase and along the weekend indicator track, a deliberate reference to precious metals and stones without the material weight. The watch carries the same Seagull calibre, visible through a sapphire caseback. A dark green leather strap completes the design.

Shepherd’s Delight takes its name and colour language from the old weather adage: red sky at night. The dial is a rich red, with purple accents marking the moonphase and weekend indicator. The palette is unconventional in horology, yet it carries historical weight. The shepherd’s warning becomes, here, a reason to leave the week behind and paint the town red. A dark brown leather strap provides ballast.

All three new watches share the same automatic movement and the same complication architecture, but each occupies a distinct emotional space. The collection reveals that calendar complications need not read as complexity for its own sake. Constraint, when treated as design material, becomes clarity. These watches prove the point with colour, proportion and the careful placement of information across the dial. They are available now through the Studio Underd0g website.
