hands
The SB05’s hands are a testament to meticulous design, blending functionality with artistic precision. Crafted with a fixed spear shape, they feature ultra-thin bead-blasted bases that provide a refined matte texture, contrasting beautifully with their polished tips.
The central spine incorporates a subtle fluted design, with gracefully concave sides that create a multi-dimensional aesthetic.
dial ring & logo plate
The dial ring frames the display with understated sophistication, featuring a nuanced mix of brushed and polished finishes. The Studio Underd0g logo plate, with its beveled edges and satin finish, sits elegantly on the dial—a subtle yet significant detail that embodies the brand’s refined aesthetic and commitment to craftsmanship.
