Attractive
Style: Dress, Color: Silver/Green Dial
I bought this on sale for $69. I find this watch attractive. However In 2 months it lost 3 minutes, not a killer but in 2023 there is no need. My last watch cost $39 and had near perfect time over a year. Then died lol. The band is heavy and impressive but. It was larger than my wrist and needed a jeweler to remove a link. That can be typical for a metal band, I’m hairy and the hair gets caught and pinches. I’m thinking of a leather band. Ok all and all, looks like a more expensive watch. I’m not happy but I’ll keep it.
