It requires nothing. Just wear it. Look at it when you need the time. I have many watches. This is beautiful. From Duncan.
I bought this watch for an anniversary gift (5/11/2018). Within a month or two, the black on the band started wearing off badly. I baby the watch, and work a desk job, and don't even wear the watch every day. Not impressed. I've seen sub $100.00 watches hold up better. It's too bad too, because i LOVE the style.
Hard to tell the time sometimes but it’s a very nice watch get compliments all the time
