Endowing their timepieces with technical elements that enhance chronometric precision, these watchmakers give added guarantee on accuracy by subjecting their timekeepers to additional performance tests
The quest for precision is a relentless one, chased by these watchmakers who are going the extra mile to put their watches through extra paces to further improve their performance. If you thought that the guidelines set by the Official Swiss Chronometer Testing Institute (COSC) were stellar, check out the ones set by Rolex, Omega and Glashütte Original. In end-2014, Omega announced that all of its watches would eventually be certified by an independent body called METAS (Swiss Federal Institute of Metrology), endowing its already impressive Master Chronometer movements with further guarantee, by testing their magnetic resistance. Rolex, too, has updated the terms of its in-house Superlative Chronometer Certification, by ensuring that both the uncased movement and the entire watch meet all its requirements. German watchmaker Glashütte Original has launched an inhouse certificate that comes with its latest Calibre 36-equipped Senator Excellence timepieces.
