Cal. 6150 was a short-lived automatic calibre from Zenith and was used in the Elite line from 2014 through 2020. It was an oversized calibre, measuring 30.00 mm diameter and 3.92 mm thick. It had double-barrel winding for 100 hours power reserve. Zenith claimed that this in-house movement would become a standard for the company’s new 42 mm watch line but no other members of the family were produced and it was quietly replaced by an updated version of the original Cal. 670 in 2020.

Cal. 6150 was enlarged to contain two winding barrels and to match the style of the time. It is likely that this larger size was intended to support a larger-diameter date wheel, moving the date outward on the large 42 mm Elite watch, but this was never produced.

Development of Cal. 6150 began in 2012 as an enhancement to Cal. 670. Although designed under Zenith CEO Jean-Frédéric Dufour, it was not designed to replace the high-volume Cal. 670 especially at the entry level. The movement was much more complex and costly than its predecessor, and was intended for higher-priced pieces. In 2014, Zenith announced that they would use Sellita ebauches rather than an in-house movement for the entry-level Elite pieces. When Dufour left to head Rolex, his successor, Aldo Magada approved Cal. 6150 for volume production. The movement was officially launched in 2015 and the Sellita plan dramatically scaled back.
