Hi there and welcome to the forum. I don't know anything about Maratac watches but thought I'd say Hi anyway.
You might have more luck posting this in the main Watch Talk Forum as this BMW forum is not generally very busy - it's mostly talk about watches actually used by the military so quite a minority interest compared to the mainstream.
Two other tips from a relatively recent newbie myself :) :
First, if you haven't already done so, try out the Forum search function as well; something as specific as Maratac should show up really easily.
Second, show us some pictures of literally any watch or watches you might already own, in Watch Talk - guaranteed to give you a good introduction :)
Have fun.
