RADO DIAMASTER PETITE SECONDE COSC
The ‘Master of Materials’ label is one of which Rado is incredibly proud, and the quest for innovative combinations of materials continues as it strives to constantly chart new territory. Only Rado has thought to combine scratch-resistant and durable plasma high-tech ceramic with a material known for its elasticity: silicon. It is this natural, light and hard-wearing material placed at the heart of the new DiaMaster Petite Seconde in the form of the hairspring that has helped this new model achieve its enviable COSC certification for precision. Obtaining COSC certification requires a movement to deviate less than -4/+6 seconds over a 24-hour period, a feat so rare it is only awarded to around 6% of Swiss-made timepieces. The silicon hairspring means the Petite Seconde automatic movement maintains the utmost precision. Not only is this watch in the top 6% of Swiss timepieces, it is also a watch that is guaranteed to stand out for its classic good looks. Featuring the typical clean, rounded 43 mm DiaMaster case and the open, clear and readable dial the line is known for, this is pure Rado. Topped off with metallic detailing and a soft leather crocodile print strap, in 2018 the DiaMaster Petite Seconde COSC is precisely what watch fans have been waiting for.
