Introducing: Studio Underd0g Launches the 04SERIES Calendar with a Clever Weekend Indicator

Studio Underd0g has introduced its fourth collection, the 04Series Calendar, marking the independent brand’s first calendar watch and its first movement developed with a partner. Time+Tide Watches reported that the project took more than two years and required 34 new components, created with Seagull. The resulting automatic caliber, the Seagull ST-2115B, runs at 28,800vph (4Hz), offers 42 hours of power reserve, hacking seconds, and an accuracy of +15/-10 seconds per day. The rotor reflects the exclusive partnership and is visible through the screw-in case back’s sapphire display.

The watch is available in two stainless steel case diameters, 37mm and 38.5mm, both 13.5mm thick including crystals or 10.5mm without, with a 44.5mm lug-to-lug and 20mm strap lugs. Water resistance is rated at 5atm. Four colorways are offered: Cloud10, Shepherd’s Delight, 0vercast, and Arabian Sky. Leather straps come from The Strap Tailor in Buckinghamshire in Nail Virginia, Chestnut Hidro Pull-Up, Emerald Virginia, and Cameo Cutter, each 20/16mm with quick-release spring bars and a stainless steel pin buckle. A stainless steel mesh bracelet with a slide-adjustable folding clasp is also available.

The calendar complication uses a pointer-date-style display with a twist. Individual windows align to a date and show predominantly light-colored portions of the disc underneath, with two darker colors emerging every five days to mark the weekends. The underlying wheel is adjustable via the crown, while the retrograde pointer date never blocks the moonphase and is adjustable via a small pusher at two o’clock.

Every watch is assembled in the UK at The D0ghouse in Maidenhead, England, where the team regulates and inspects each example before delivery. The 04Series Calendar will be available starting November 17th through Studio Underd0g’s website and by appointment at The D0ghouse. Retail prices start at €800 / US$1,100 / £750 / CHF 800 / C$1,300 / A$1,400 / AED 3,500, with free worldwide shipping and a limited two-year warranty.
