2018 marks the 50th anniversary of Jaeger-LeCoultre's 'Memovox Polaris' - one of the horologist's most iconic models. Set with the same black dial as the original, this 42mm chronograph is encased in stainless steel and fitted with a discreet tachymetre scale. Through the transparent case back you can glimpse the inner workings of the 262-part 751H automatic movement - the brand compares it to admiring a sportscar's motor. The brown leather strap is a classic choice for the office or business meetings.
