It's a good look.
Color: Black/Brown/White, Color: Black/Brown/White
Very nice watch. I was complemented twice in 3 days. It fits well, looks great. I'm trying to look at screens less and teach my kids how to tell time on an analog clock face. 4 stars because, while the strap on the outside looks like it's a nylon/fabric wrist band, the inside is leather. My wrist has gotten pretty sweaty as a result. And there is a VERY audible 'tick' involved with this watch. I'm a contractor and have moderate hearing loss, but I've noticed the tick when I'm sitting quietly in my living room. If a ticking clock drives you nuts, I would not recommend. Most of the time, I am in a locale so noisy, it doesn't matter. They want a jeweler to change the battery, which, as a guy who fixes stuff, I don't love, but I've got some time before I think about that. No pun intended. I'm happy with this purchase. Good for the jobsite or a hot date with my wife.

Most Dependable and Accurate Watch I Have Ever Owned
Color: Black/Brown/White
I bought this watch in August 2022. It is now January 2026. I have worn it almost every day and every night. I mow my yard with it on, wear it for funerals and weddings but always take it off when taking a shower. I have owned many watches in my 77 years including a Rolex but will say this is the finest and most accurate watch I have ever owned. It is not fancy nor flashy but dependable and keeps PERFECT time. It is a timex and I am proud to wear it. My only recommendation is they enlarge the window showing the calendar day and wish they would include the day of the year. Thank you. A+
