Handsome watch!
Color: Retro Brown band & Black bezel & Blue dial
My 13 year old grandson wanted an “old fashioned” watch so I gave this one to him. He is obsessed with it and wears it every day.

Don't Waste Your Money
Color: Retro Brown band & Gold bezel & White dial
This watch is a complete disappointment. Right out from the box, I adjusted the time per the instruction manual. After finshing adjusting the watch, I pushed the crown in (two clicks). The second hand started movement after almost 10 seconds. From then on, the second hand was stopping and going by itself. Within less than anhour, the watch was behind almost 25 seconds. It is a piece of junk. I would not advise anyone to buy this watch.
