Beautiful and very rare Omega Sensor Quartz calibre 1640 from the late 1970s. This digital Sensor watch by the Swiss top brand Omega has extensive chronograph and alarm functions. Apart from the time, it has 9 different functions in total. - Chronograph - Countdown - Appointment alarm - Wake up alarm - Hourly signal - Agenda 1 - Agenda 2 - T2 (GMT) - Calendar The full stainless steel case measures 35 x 39 mm, a sizeable watch. This Omega watch is rarely offered and will only increase in value. The Omega is equipped with a full stainless steel case and is in very neat, unpolished condition. The watch comes with the original steel strap, full length (20 cm max.) The 1640 movement was fitted with a new battery and so is ready to be enjoyed for years to come. All functions work excellently. So also the Sensor bar, the sound and the lighting. The screen has a dark spot on the left but all the information is clearly legible. Please see the photos. In short: a hip retro LCD watch from Swiss leading brand Omega. Besides being a wonderful watch, it is an investment that will retain its value. Will be packaged with care and shipped by insured post.
