For $100 is it a very nice watch, and I like it. (as long as the gold plating does not fade too quickly.)
I have TagHeuer, and Omega, but I also have several watches I wear as daily watches that are Seiko Kinetic, Fossil, Guess, and other ones I cannot remember.
Tags and Rolex kind of watches are too expensive to wear all the time. If it looks good, and you brother will like it, then is good watch.
