Old Jaeger LeCoutre - Can Anyone Tell Me About It?

[BigGingerBob]

Hi, below are pictures of my Grandfather's JLC. I have no idea on age, model or value but I was hoping those with knowledge of these things can tell me a bit about it.
I know JLC are a top end manufacturer but my knowledge of old.models is non-existent.
Neither me or my dad are sure whether we like it or not but I suplose it will look good with shirt and jacket.
