The “Ingenieur-Chrono-Alarm” : IWC’s latest design is making its debut
in Basle this year. It is built around “Calibre 630”, the most compact
chronograph movement made that combines quartz precision and traditional mechanisms, plus an alarm device with piezoelectric release. Seven hands or pointers, one fast-setting calendar, two stop crowns, two pushpieces...and a water-resistant, non magnetic case. (IWC - International Watch Co., Schaffhausen - “Ingenieur-Chrono-Alarm”)
