Cover brand Switzerland watch. Model Co51. Links included. There is olive green hue on watch that’s hard to see with pictures. Purchased over 5 years ago so international warranty has lapsed. Will need new battery. Still a great watch that my parents bought for me as a grad gift. Comparable to this on Irismo watches. https://www.irisimo.com/files/product/48461/COVER-CO52.06.jpg
