A quartz Chronometer

I have a quartz chronometer that my brother in law left behind when he died last February. It has no numbers, just a double ll for 12 and a l for the rest, and four lines between. There are little light thing around all of the hours and one light thing for each l . When I take the clock out, there is a place to put 6 AA batteries. There is a thing that connect to it on the bottom . That is all I have. However on the bottom of the clock there is something you can connect ( I think ) to set the time, something that I do not have. If that is what I need to set the time, I need to know where I can find it. Please let me know if that is possible.
