The Jacob & Co. caliber JCAA11 is an automatic dual time zone movement two independently set time indicators. This calibre is found in J&Co’s ‘The World Is Yours’ timepiece, introduced on August 23, 2023 (retail price $59,000.00 USD).

Base Caliber:

This caliber uses a module produced by Concepto to achieve the dual time zone complication. The module is attached to the top of a reworked ETA caliber 2892A2 base framework.

In Jacob & Co.’s own words:

“The world Is Yours Dual Time Zone indicated two time zones, complete with hours and minutes. Each zone can be set down to the minute. It is the only way countries with unusual UTC time offsets, like India, can display both local time and home time accurately. The crown, located on the right side of the case, has three positions. Winding, time setting for the lower time zone, time setting for the upper time zone. It’s up to the wearer to choose which one is local time.” –Source

Unfortunately, despite numerous videos of this model, including computer generated animations and videos filmed by popular YouTube channels, Caliber Corner could not find even one video of the time-setting process in action.
