Jewelry, Eyewear and Watch Design L1 All Blue Watch by Lars Hofmann The design of the L1 All Blue reflects the architecture, landmarks and style of the German capital in a captivating blue color. A sun-cut dial for even more colourful depth. And the seconds hand in Serenity Blue adds an additional touch of blue to the watch. A Stainless steel case made of especially pure 316L surgical steel and the matte blue finish perfectly accentuates the closed composition of the casing. Superluminova on the hands and hours highlights the look at night. The L1 All Blue reflects all the variety of the color blue.
