Ingenieur Chrono Alarm With the «Ingenieur Chrono Alarm» another variation of the Genta theme was launched in 1991, this time adding chronograph as well as alarm complications to the Ingenieur line. Thanks to its diameter of 34 mm and its military looking main dial, the «Chrono Alarm» gave a more adult impression than the prior «Chronograph» (ref. 3734). The model range seems to have been quite effective. Nevertheless it was already missing from the catalogue beginning with 1998, most probably making way for the «Automatic Alarm» within then launched GST line. The «Chrono Alarm» was however still on stock, with the last pieces being delivered as late as 2000. Like its sibling, «Ingenieur Chronograph», the «Chrono Alarm» was equipped with a meca-quartz movement belonging to the calibre 630. These hybrid calibres were produced by Jaeger-Le Coultre for IWC and combined quarz-controlled stepping motors with a mechanically driven chronograph. In the case of the Chrono Alarm's calibre 633, it was furthermore enhanced with an alarm function. These days, the «Ingenieur Chrono Alarm» belongs to the most popular quartz models of the Ingenieur line, here and there even being regarded as a collector's item. The main reason is of course its calibre 633 which belongs the technical marvels among the quartz movements used by IWC. Source: http://www.moeb.ch/Ingenieur/11e_ChronoAlarm.html, as of 09/25/2011.
