As we can see from the patent, the sliding leather case that transforms into a stand is a recurring theme that was widely used across retailers and watchmakers. This is most likely because of its ease of use and handling, in addition to the fact that the stand doubles up as a protective case for the glass and dial.
Additionally, according to the Jaeger-LeCoultre archives, the Ados clocks came in a variety of models, including the Ados Mignonnette, the Ados Baby, the Ados (Baby) Barometer, the Ados Chronograph, the Ados Standard and the Ados Standard Barometer, with the Standard models available with or without alarm function. Further to this, there were also the Indos clocks, which were “semi-open” clocks which made use of a completely different sliding mechanism. Rather intriguingly, when the Ados and Indos clocks were introduced to the US public, they were referred to as ‘Little Slam’ and ‘Grand Slam’ respectively.
