Launched in 2013, Calibre 898 is a derivative of the ultra-thin Calibre 899 and closely related to Calibre 896. Unlike Cal. 896, however, Cal. 898 has no seconds subdial (or indeed any seconds display) and adds an optional day/night indicator. All three versions measure just 3.3 mm thick like Cal. 899.
There are three JLC 898 variants
The 898 is an automatic movement 3.30 mm thick. It runs at 28800 vph and has a power reserve of 43 hours.
Jaeger-LeCoultre currently uses this calibre in thin round watches
