LUXE BLACK reinterprets the standard 2100 series through a lens of modern refinement. By eliminating excessive ornamentation and focusing on a disciplined sense of minimalism, this series pursues a timeless quality that does not fade with age. Set against deep black tones, subtle contrasts emerge, using G-SHOCK toughness as a foundation for a product defined by quiet presence and controlled shine. The dial features a matte black finish with a fine textured surface that suppresses reflections and absorbs light. Newly developed, slim hour and minute hands with extended proportions are paired with redesigned vapor-deposited hour markers, balancing legibility with refined surface quality. Each dial element has been individually reconsidered to express the essential qualities of a product designed for long-term appreciation.
The GM-2100LXB combines a black ion-plated metal bezel with a black resin band. Silver accents applied to the inset dials, along with vapor deposition around the perimeter of the glass, enhance depth and material presence.
