====== JLC 470 ======
**Calibre 470** was a [[chronometer]]-grade [[hand winding]] movement from [[Jaeger-LeCoultre]].

Originally used in the military Mark 7 A, Calibre 470 was a hand-winding movement with great precision. It evolved into the **Calibre 488 SBr**, used in the Mark 11, which added [[hacking seconds]]. **Calibre 468** was similar. The next revision was **Calibre P 478 BWSBr**, the movement used in the legendary [[Jaeger-LeCoultre Geophysic]] chronometer of [[1958]]. The 478 added [[shock protection]] and a [[swan neck regulator]] but was otherwise similar to the 488.
