Minimal parts, maximum precision! This Swatch GJ900 Promo is a luminous watch with its yellow dial that can also be seen in the dark thanks to its built in little light. The top of the plastic strap is carried out in silver grey metallic and the bottom strap in turquoise. The fluorescent yellow transparent plastic case frames the citrine dial. The black hours and minute hands are filled with white and the second hand is completely white.
