Are all Calibre 11 movements made equal?

    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).

    I'd expect the differences are due to improvements and/or cost reduction. In the case of the ETA base being switched for a Sellita, the Swatch Group parts restriction probably played a role in that too.

    I understand the ETA to Sellita switch. I was more interested in the variations/model line up of the Dubois-Depraz modules.

    Right, that's what I meant with my first sentence - DD probably found ways of either improving the performance or reducing the production cost of the modules, and so introduced new models.

    Yes OK. It's a shame there aren't any details available.

    But, Calibre 12 and Calibre 11 suppose to be the same, right ?

    The base calibre is the same.

    For the chronograph module, other than the position of the crown, that it is what I believed too.

    The original Calibre 11 was modified into the Calibre 12 as Heuer responded to feedback about weaknesses in the original. You can find more in-depth articles with a decent Google effort, and it's pretty interesting. But we're talking about the modern so-called Calibre 11 and 12, which are cheap base 3-hand calibers mated to Dubois-Depraz chronograph modules. I don't think the modern 11 is the same as the modern 12 - I'm sure it took more than just a simple rotation of the watch module to achieve the left-hand crown. I'd expect more modification of either module was necessary

    I forgot about the most important difference which is the crown position. Yap definitely there's the difference. :thumbsup:
