1st Logo (September 13, 2019)
Logo: In a dark-tinted cloudy area, a cheap-looking 3D submarine jumps into the water made of polygons, as the camera shakes a bit. The text "submarine", wipes in from the bottom in a stylised font as "AMSTERDAM" fades in below. The background turns black, and then the logo is wiped away.
Technique: CGI animation.
Music/Sounds: A splashing sound.
Availability: Only seen on season 1 of Undone.
2nd Logo (April 29, 2022)
Logo: On an ultra dark cyan background, there is a minimalist moving submarine with its spotlight on, lighting a small portion of the screen in gold. It finds a portion of the company name before revealing the whole text on a gold background with it moving closer to the screen and eventually next to the stacked text.
Technique: 2D animation.
Availability: Seen on season 2 of Undone.
