Product description
The Swatch × Omega Bioceramic MoonSwatch “Mission to Neptune” (ref. SO33N100) is a striking addition to the MoonSwatch collection, combining bold nautical aesthetics with the legacy design of the Speedmaster Moonwatch.

• Design & Aesthetic:
  The case and dial come in deep navy-blue tones that evoke the mysterious, dark depths of Neptune. Complemented by a black Velcro® strap, the contrast here is strong and stylish. All hands and hour markers are rendered in crisp white, ensuring excellent contrast and legibility. The bezel carries a white tachymeter scale set against blue, reinforcing the sporty chronograph character. 

• Key Features & Heritage Cues:
  As with the rest of the MoonSwatch line, it includes recessed subdials, a fine circular texture on the dial’s outer ring, the Speedmaster logo alongside the MoonSwatch and Omega × Swatch branding, and the signature “dot over 90” on the tachymeter bezel. The glass is biosourced, and it includes the etched “S” in the center. Hands and hour markers are treated with Super-LumiNova® for glow in low light.

• Case, Movement & Build:
  The case is made of Bioceramic, combining ceramic with bio-sourced material, giving a lightweight yet durable feel. Diameter is 42.00 mm, thickness about 13.25 mm, lug-to-lug approximately 47.30 mm. The movement is quartz, chronograph style. Water resistance is 3 Bar (≈ 30 meters). 

• Wear & Vibe:
  Mission to Neptune stands out for its deep blue styling—more dramatic and moody than some of the pastel or lighter MoonSwatches. It appeals to those wanting a strong, bold look with a connection to space/astronomy themes. While sporty, it remains wearable daily thanks to the strap, comfort, and recognizable design. Some prior models had concerns with dye staining, but Swatch appears to have addressed these in newer batches.
