The case's transparent bottom allows viewers to admire the NH38A automatic movement. Manufactured by Seiko, it has an oscillating weight with Côte de Genève decoration.
The dial, which comes in silvery white or semi-gloss black, offers easy reading thanks to polished rhodium-plated hands, a dauphine style, hours and minutes, as well as polished, arrow-shaped indexes. The central second hand is blue steel.
The dial also includes a double index at 12 o'clock and small lines indicating the minutes, which are white or black depending on the colorway. The opening on the balance at 9 o'clock contributes to the model's horological dimension while reinforcing the elegance of the lines. Finally, the watch is mounted on a two-strand, interchangeable strap in matte black, chocolate brown, or gray vintage leather, all neutral tones that match the watch's timeless aesthetic.
