We all know that the Calibre 11 movement is a base ETA 2892/2 or a Sellita SW300 with a Dubois-Depraz chronograph module bolted on to it. However, there seem to be various different DD modules in use that all fall under the banner of the Calibre 11. Examples that I have found include the DD 2002, DD 2006, DD 2018, DD 2021 & DD 2022. The Dubois-Depraz web site is typically (for the the non-consumer facing watch industry) brief and contains precisely zero details on their model line up. Can the Calibre11 collective shed more light on this? The Calibre 12 seems to be similar but with fewer variations (DD 2002, DD 2008 & DD 2019).
