Junghans Max Bill Automatic Black No-Date 027/3400.00

The design goes back to Max Bill, the Swiss architect and designer who studied at the Bauhaus in Dessau. He created a series of watches for Junghans, the first launched in 1961. The current black no-date Automatic, 27/3400.02, has a matt black dial with luminous hands and printing, the self-winding J800.1 movement with up to 38 hours of power reserve, and a domed sapphire crystal in place of the acrylic one on this reference.

The 027/3401.00 is the same watch with a grey dial and the 027/3500.00 with a silver one, while the 027/4701.00 Black Stick shares the 38 mm case and black dial. The Max Bill Quartz Black (041/4462.00) keeps the 38 mm diameter in a 7.9 mm case against this watch's 10 mm, and the Hand-Winding models drop to 34 mm. It takes a 20 mm strap.
