 " Junghans 027/4200.00 Automatic Watch"
"The Junghans Meister Calendar 027/4200.00  is a 40mm men's automatic watch with a stainless steel case and a white analog dial protected by mineral crystal. It uses a J800.3 caliber self-winding mechanical movement that can be manually wound and hacked (the second hand stops when the crown is pulled out). It ticks 8 times per second which gives the second hand a smoother movement than a quartz watch which ticks once per second.  The watch should run for up to 38 hours when fully wound and will self-wind when moved."

"Iconic design, true to the original penned by Max Bill in the 1960's, the Junghans Max Bill is elegant and refined, as well as perfectly simple. Inside the watch is a Junghans self winding automatic mechanical J800.1 movement, with the bare necessities of second, minute and hour, as well as date displayed at 3 o'clock. This is displayed on a matte black dial, beautifully curved, with hour and minutes marked clearly and simply with very slim batons, and luminous markers at the 4 quarters. The case is a stainless steel construction, with curved SICRALAN coated hard plexiglass, true to the original. The watch fastens on a soft black calfskin leather strap."@en
