Does anyone remember this Marantz?

I'm hoping someone out there has information on a Marantz receiver I bought new in the mid 80's. I no longer have the receiver and am hoping to learn it's model number and any other possible details. What made it unusual was the presence of a large blue digital clock display (doubled as an alarm) in the middle of the receiver's otherwise traditional face. The few other facts I can recall are: It was black. I think it had 100 watts per channel. It had a remote. I really liked it. I've done some online searches and can't come up with anything. Any ideas? Thanks!
