Jaeger 5002 21 - more info required

Hi all,

Just chasing a bit more info on a Jaeger 5002 21 that I have inherited.

I know the band is non original (and it's terrible!), but there is very limited info on the watch online.

I know it has a caliber 900 movement (and this one isn't working unfortunately, I will have to get it repaired / serviced) and that's about it.

Any ideas about when it came out, how many were made, and the name of the model? Also what colour the original band might have been so I can source a new one that closely matches the original?

Thanks in advance.
