While diving, precision is essential. The introduction of two versions equipped with a COSC-certified caliber is a further step towards perfection.
The “Contrôle Officiel Suisse des Chronomètre” is an independent Swiss chronometer certification body that issues a COSC certificate after careful verification of the performance of each movement. Founded in 1973 and located in La Chaux-de-Fonds, it is a well-known non-profit organization dedicated to the testing and certification of Swiss watches.
The term “chronometer” is assigned to a precision timepiece only after passing specific tests to determine that the average error variation falls between -4 and +6 seconds every 24 hours. The COSC definition of chronometer is thus synonymous with quality
and reliability. A certified watch has a unique number engraved on the movement and reported on a printed certificate issued by the COSC.
The COSC Certified 1521 models are the cornerstone of the 1521 Collection. Not only is their mechanical performance outstanding, but their look is equally extraordinary. They are in fact the first steel models to feature a case with a bi-lux finish, i.e. satin-finished with polished bevels for maximum elegance.
To make the 1521 COSC watches truly reliable instruments in all underwater adventures, the technical characteristics are designed to ensure maximum reliability in all situations. The bezel, equipped with indicators made in SuperLuminova, and the dial with applied indexes, guarantee high legibility even in the most extreme diving conditions where it becomes important to keep track of every single minute.
The 1521 Classic COSC comes in a box set that includes a waterproof case, a COCS certificate detailing the results of the tests carried out by the organization, a unique Squale identification certificate issued for each individual watch, and an additional vegetable-tanned leather strap. This particular method of tanning increases the water resistance of the strap and makes it more comfortable to wear.
