One of the flagship products of Jaquet Droz, the Grande Seconde Quantième was launched in 2011. This year, at BaselWorld 2014, the watchmaker based in La Chaux-de-Fonds introduces major changes to this model whose complete name is now Grande Seconde Quantième Ivory Enamel.
The movement sees the addition of a silicon balance spring and inverted horns on the pallets fork. Silicon offers several advantages compared to other materials: it can withstand shock and variations in temperature and pressure, and it is resistant to magnetic fields, so delivering perfect stability over time.
The self-winding movement with its gold oscillating weight, visible through the transparent case-back, is meticulously finished with circular-grained plates, chamfered and circular-grained wheels, and Côtes de Genève decoration.
The Grande Seconde Quantième Ivory Enamel's dial is available in red or white gold and with a diameter of 39 mm or 43 mm. The precious double level dial has been double enamelled using the Grand Feu enamel technique. The two sub-dials - the upper indicating hours and minutes, the lower used for seconds and date - describe a figure eight, the brand's favourite number.
Gold hands are used in the red gold version while blued steel hands are the choice for the white gold model. The video below better shows the beauty of the enamelled dial.
