Jaeger-LeCoultre caliber 896 is an ultra-thin automatic watch movement with 32 jewels and a beat rate of 28,800 vph. The notable features of this calibre are that it is a true no-date with a small seconds subdial at 6:00. This style is reminiscent of classic pocket watches.
At 3.98mm, the cal. 896 is categorized as an ultra-thin movement. JLC refers to it as “ultra-flat”.
According to JLC, each caliber 896 is tested rigorously for 1,000 before leaving the factory.
In Jaeger-LeCoultre’s own words:
“In its pink gold version, the Master Ultra Thin Small Seconds watch is housed in a fine-gauge (8.1 mm) 39-mm case, designed to accommodate its ultra-flat movement, the Jaeger-LeCoultre Caliber 896. This mechanical self-winding movement marks the hours, minutes and seconds with exemplary precision.” -JLC Master Ultra Thin Small Seconds official product page
