Review: Great daily use watch - I bought this in 2022, it's now 2026 and it's still my daily watch. It's lost plating (see photo) but it works great and I really love it. I have tiny wrists so I had a couple links removed at a jeweler, but that was fast and cheap. I take it off to shower, and sometimes for swimming, but I've probably forgotten and left it on more then I've remembered to take it off. Keeps time, little timer is great and I use that function daily to time my tea steeping. Small and pretty, classy enough to wear with dresses. Easy to change the time.
Review: Great watch!! - I wear this watch all the time, it’s great. Good price and not too clunky or too dainty, and looks nice for a digital watch. I like the way the strap adjusts, but there has been a few times where the latch has come undone so it’s important that you secure it well. Haven’t noticed anything with the battery life but it seems good in that regard, and the time reads accurately (once you set it up). It’s comfortable for a metal watch, unless you tighten it too much. Seems durable but I haven’t tested it in water — I always take it off before showering, just to be safe, but I’m sure it’s fairly water resistant.

**Q: Is anyone concerned about or know anything about the birth defect warning on this watch?**
A: You may be seeing a warning required by Proposition 65 in California that applies to numerous chemicals and substances.  I generally don't pay much attention to it because it occurs so widely that I don't see how to avoid it.  From wikipedia: "Proposition 65 is administered by Cal/EPA's California Office of Environmental Health Hazard Assessment (OEHHA).[2] Proposition 65 regulates substances officially listed by California as causing cancer or birth defects or other reproductive harm, in two ways. The first statutory requirement of Proposition 65 prohibits businesses from knowingly discharging listed substances into drinking water sources, or onto land where the substances can pass into drinking water sources. The second prohibits businesses from knowingly exposing individuals to listed substances without providing a clear and reasonable warning. "

**Q: Do you have a same one with the same features (e.g. timer) for man? Thanks!**
A: I believe there is a men's watch that is very similar

### ⭐⭐⭐⭐⭐ Great watch!!
*by L***K on October 29, 2025*

I wear this watch all the time, it’s great. Good price and not too clunky or too dainty, and looks nice for a digital watch.

### ⭐⭐⭐⭐⭐ Fashionable and Functional!
*by S***S on January 15, 2026*

I am in love with this new watch! It is light and pairs well with dainty jewelry, but with all the function I need. The metal looks shiny and not cheap, but the watch is not too heavy. As other reviewers mentioned, there is no back light button for reading the time in the dark, but I am okay sacrificing that bit of function for the look. I've been wanting a metal watch that has a digital clock face but is still dainty and goes with everything, and this is perfect. I have pretty small wrists too, so I was worried it might even look to big/chunky on me, but it's perfect! I was also worried this watch would catch my arm hairs and be painful –– but I'm shocked at how comfortable it is. It doesn't catch my arm hairs, and I have a lot of them haha. I would not be able to wear a watch that caught my hairs. To resize the band, you move the latch, rather than removing links. My local watch repair shop did it for me for free, but I'm sure you could do it at home too if you look up a tutorial. Overall I'm super happy with it!
