Rolex 3235 Movement

Rolex's Datejust 41 and Pearlmaster 39 models come equipped with their new generation movement, Calibre 3235. This movement is protected by 14 patents and features many of the watchmaker's latest tech innovations, including their blue Parachrom hairspring and Chronergy escapement.

This movement improves upon the precision, reliability and power reserve of its predecessors. With a 70 hour power reserve, it truly does represent the future of Rolex's integrated watch production. All Rolex watches are subject to extensive in-house testing to ensure that they will meet the requirements of a superlative chronometer.

In order for their timepieces to receive the Rolex Superlative Chronometer Certification, they must function at a precision of -2/+2 seconds per day after casing. Rolex has updated their certification requirements as recently as 2015 to ensure that all of their timepieces are worthy of their green seal.

The video clip below provides some insight into the process of putting together a Rolex movement at their production site in Bienne, Switzerland.
