Although JLC 'might' have confirmed authenticity (how? by looking at the watch in person? and, more importantly, who, and did they provide a certificate?), I am totally certain this dial is a repaint.
While one can argue that the watch is indeed authentic (as its case / movement / hands, and base dials were indeed produced by the LeCoultre manufacture and as such this is not a counterfeit), the dial is very wrong and has obviously been repainted, in a scheme that doesn't work with what the watch should look like originally (and the repaint job is poorly done).
Stay away from this one (or buy it for parts only ! )
