Jaeger LeCoultre Alarm Timepiece

Hello Everyone:) I'm reposting this, as i'm new to this site and not sure how to edit articles. This is a Jaeger LeCoultre Alarm type of Timepiece. I am looking for any information about this item, that someone with knowledge in this area may have. I would like a value on it, if at all possible. I feel it's in fair to good condition...although the black leather case is not in good condition, at this point. This belonged to my late Father-in-Law, who was an NYPD Captain. He's not around to give me any information on the item. I can't part with this item but would like to know about it. I do believe it is from the 1980's but could go back to the 1970's. Any information would be greatly appreciated!!! Thanks so much for your time, in advance!
