IWC has been transitioning to in-house movements since 2000, enhancing the reputation and technical features of their watches. Part of this development includes the production of specialty high-end movements. The Cal. 94000 family is the basis for many of these since its launch in 2011. It uses two mainspring barrels, providing power for complications including a tourbillon and specialty digital time display. This was a departure for the company, which had previously relied on a single barrel design for long power reserve movements but suffered poor isochronism as a result.
Cal. 94200 debuted in 2018 powering the IWC Tribute to Pallweber wristwatch and pocketwatch. In this application, the two mainspring barrels are de-coupled, powering the display and timekeeping separately. This is reminiscent of sister company Jaeger-LeCoultre's Duomètre movement family. The hand wound movement oscillates at 28,800 A/h, unlike most of the Cal. 94000 family, and has a 60 hour power reserve. It has 54 jewels and is made up of 290 components.
This movement gives the Pallweber series its unique time display. Rising hours are shown digitally above a double-wheel rising minutes display at the center. Small seconds are below in the traditional place. It is a large movement, measuring 37.8 mm in diameter though it is just 7.3 mm thick.
