This unique silhouette comes from the "AB2" silhouette designed by Deterlums in 1984. Clean and simple dial, luminous hands with luminous glow in the dark for high visibility. As with all brown products, ease of use and functionality is first priority, and it also shows in the backlight. The backlight function improves your visibility so you dont have to worry about checking the time at night. The signature yellow second hand is synonymous with the brown design aesthetic.
