If Corum manages to endow the Heritage collection with an image as strong as that now enjoyed by the Admiral’s Cup and Bridges lines, the feat will quite naturally be termed a tour de force. In 2010, the brand which has been on the rise again since the middle of last decade revived two of its emblematic historical models. This time, the Heritage collection is releasing two limited series highlighting the Grand Precis, presented in 1957 and exactly reproduced in every detail except size – since the new version has a diameter 2.5 mm smaller. Even its movement is composed of original parts and distinguished by an extremely large balance boasting a precision that inspired the name of this classic model with its delightful vintage look. The back of the case in rose or white gold reveals the magnificent finishing of the calibre through the sapphire case-back of this collector’s item.
