The current Studio Underd0g Steffany Blue is the 02SERIES Generation 2 field watch, reference 02SBMI. Its official listing specifies a 37.5 mm stainless-steel case, a manually wound Sellita movement with a 63-hour power reserve, and a layered luminous dial. It is a different watch from the 2024 limited-edition Steffany Blue, which used another movement and had a shorter stated reserve.
Which Studio Underd0g Steffany Blue is this?
The current model is Steffany Blue (Gen2), one of four colorways in Studio Underd0g’s 02SERIES Generation 2 collection. The brand presents the series as a playful take on a field watch. The current product reference is 02SBMI. Studio Underd0g’s product page provides the model-specific specifications; its 02SERIES collection page shows the wider color range.
Do not use the original Steffany Blue’s specifications for Gen2. The earlier 2024 limited edition had a 37 mm case and a Sellita SW210-1 movement with a 42-hour reserve, according to Perpétuel’s coverage. Gen2 instead uses the SW200-2 M Power+ and the brand states a 63-hour reserve. Fratello reported that the Gen2 watches became available on July 7, 2026. Fratello’s launch report also describes the updated generation.
Case size, water resistance and wearing dimensions
Studio Underd0g lists the Gen2 case at 37.5 mm in diameter, 11.5 mm wide and 46 mm from lug to lug. It is made from 316L stainless steel and rated to 10 ATM water resistance. Those are the current model’s published figures, not measurements for the original limited edition. The 18 mm strap width at the lugs tapers to 16 mm at the buckle.

What is distinctive about the dial?
The dial is built in layers rather than being a single flat plate. Studio Underd0g says a 1 mm sapphire top disc sits above a brass base dial carrying seven layers of X1 Super-LumiNova. That construction is the defining visual and luminous feature identified in the brand’s listing; no independent brightness or legibility test is established here.
Movement, winding and power reserve
Gen2 uses the Swiss Sellita SW200-2 M Power+. It is manual-wind, includes hacking seconds, runs at 28,800 beats per hour (4 Hz), and displays hours, minutes and seconds without a date. Studio Underd0g specifies accuracy of -7/+7 seconds per day and a 63-hour power reserve.
