    My rose gold wedding band is in the photo, for matching purposes, it is more of a bronze which works really well with my pale red head skin tone. It is not so girly that a man couldn’t wear it. I think it’s stunning. As with all casios easy to set and use. The strap was easy to fit to my wrist size. Overall definitely give five stars

    It looks great, from a couple of reviews I thought it was going to be heavy. But it feels just right! I have used it for an entire week (by the time of writing the review), doesn’t pull on delicate clothes, no skin staining even if you wash your hands with it. Great quality (my last CASIO worked great for 5 years until I had an accident and killed it) hope this one lasts as long

    This was bought for me as a birthday present, although it says men’s I’d say it’s actually a women’s watch. I really like the colour and style of it and is a nice size. I have slim wrists, but the strap is easy enough to change but is a bit stiff. You have to make sure you get the piece that slides up and down in the right place so it can clip back in.

    I got this for my wife.
    She loved it. Time and date easy to set on it.
    It bleeps every hour. The alarm clock is easy to set and useful. Its comfortable to wear. The fact it lights up is helpful if you wake early hours of the morning and need to see what time it is without switching the bedroom light on. It’s not big or heavy. Not sure if it’s rose gold but still a nice colour. Well worth the price.

    I love this watch.
    I do have to be honest and say it does keep coming undone all the time by itself.
    But its so light and looks great on.

    I bought this for my daughter, this is her second one. she loves them. The only thing I would say about it was that the adjustment clasp was quite stiff.

    Golden Review Award: 3 From Our UsersI cant stand the tick of non digital watches, nor can I stand having a large item on my wrist. The colour, lack of tick and size of this made it perfect for me. However the screen lets it down. The plastic scratches very easily. I have only had mine for a few months and the face is rather damaged looking – and its not been subject to unusual usage.

    I would pay more if they had gorilla glass to avoid being so easily scratched.

    The watch is amazing. The colour is a bronzie pink very beautiful!
    I don’t know if this is a original one or not, but the quality seems good, and the characteristics are identical to the original model.
    The bad thing was that the package I received was completely ruined, like, opened, and with no protection around the product.
    I don’t know if they sent it this way, or if was a consequence of the transportation, but the fact is, I could receive it without the watch inside,
    or with it totally destroyed.
    Amazon, be carefull with this next time!!

    Golden Review Award: 2 From Our UsersI fell in love with this watch when i saw it on someone else, it is gorgeous. Classic with a vintage touch but modern and urban. Femenine but not too girly. Not overly shiny, more like a glittery underline matt color. Also, not heavy to wear at all! I am still in love with it as you can see.

    5.0 out of 5 stars In love with this vintage beauty

    I was a little bit disappointed that the watch is not in a proper box, it just comes in a small cloth bag that made me wonder if is a genuine Casio watch. I love it anyway 🙂

    Golden Review Award: 19 From Our UsersWho knew? Apparently the iconic Casio F-91W watch has a myriad of knock-offs, all over certain auction sites. Not sure about this specific model, but I’m sure there are clones out there in the wild…

    Luckily, this seems authentic. Although it was a Warehouse purchase (listed as “repackaged”) it actually came in a Casio box with Casio tag and documentation.

    Curiously this is listed as “Rose” colour but as it’s Unisex, and would probably be considered a bit of “girly” watch colour, I would say it’s more Bronze and could happily be worn by a man. The case itself isn’t too big or small and could be worn by either gender.

    This is a gift, so I had to reset the date and time after receiving it but it’s simple enough to do.

    Great bargain, looks good, works well as a daily beater (been checking it keeps good time – all fine). It’s 5 BAR water resistant so I’m sure it will cope in the rain, on day trips hiking and doing more arduous stuff (the recipient is an adventurer at heart and goes camping, hillwalking, etc). I assume the battery will last longer than typical analogue watches, as digitals tend to go on and on….

    Posted pictures so you can get a better look at the Rose (cough, Bronze) B640WC-5AEF. The instruction booklet was a bit battered (to be expected for a Amazon Warehouse purchase), that’s how it arrived, but everything else was in perfect condition.

    Re, Casio fakes, what to look out for: The metal bracelet is a dead giveaway, usually it’s not well-finished, has sharp edges and “rattles”. The movement won’t keep good time. Some even have “disco lights” (that cycle different colours) instead of one-colour illumination. Copies also don’t have serial numbers on the back of the bracelet – beside the pins that attach to the case.

    I can see an Amazon reviewer has problems with the clasp – others with the longevity of the finish – both signs of fakes but it’s hard for me to comment on a new item. I’ll update if I have issues with the Rose (or Bronze) coating. Others are complaining about the face being easily scratched, again, hard for me to say, so soon.

    (About the F-91W specifically – the “CA510” display, when you press the right button for 5 seconds, doesn’t work on most knock-offs. All digits display simultaneously when you press all buttons at once on a genuine F-91W – the B640WC-5AEF doesn’t have these little quirks.)

    5.0 out of 5 stars Lovely Watch, Looks Bronze Rather Than Rose, Great Choice As A Reliable, Tough, Daily Beate

    Golden Review Award: 5 From Our UsersBought this in may as a birthday present for myself. Love the colour… even though the bracelet part is copper more than it is rose gold (the actual watch part is rose gold) it looks absolutely fab!

    5.0 out of 5 stars Would definitely buy again!

    I really love the watch and although some of the rose gold sheen has started rubbing off already. It’s not majorly noticeable but a little annoying as I’ve only had it since February.

    Got this as a Christmas present for my sister in December 2015 and she still has it today (the end of 2016) and it has no scratched or any damage on it at all and we think it will last a very long time. I am very pleased with this product.

    My wife wanted one of these after seeing someone else with one on our honeymoon? To be honest I thought it’d just be a cheap and nasty watch but it’s very well constructed, feels solid and looks great. It has all the typical functions of a general CASIO digital watch, at a fantastically low price.

    It arrived within 2 days of ordering in protected packaging and everything was as advertised.v

    So far there have been no issues and I’d recommend it to anyone who is considering this watch.

    Love having the convinience of a digital watch to be able to easily check the time.

    The watch is simple to use and has 4 buttons. Among all features I like that is has a button to light the display and displays the day, date and time.

    Simplicity was key for me and keeping the display simpe is great for me.

    The watch is ajusted by a slider on one end of the watch fastening which means even with small wrists like mine you can find a perfect comfortable fit.

    Would definitely recommend

    Golden Review Award: 2 From Our UsersI love this watch! I have never really been a watch person and constantly forget to re-put it back on after a shower (or forget to take it off before I get in), but now I am lost if I dont have this on my wrist.

    I love that as well as an alarm to go off, on either a set day every week/month or every day (to get me out of bed for work), I can also set an hourly beep (reminds me to keep drinking water), a countdown timer (endless uses), and a stopwatch!

    When I first got this watch I was having to take antibiotics at set times and this watch proved very helpful in reminding me to take them (I am normally useless and setting a phone reminder is often a waste of time as I can leave my phone on a desk and be sat another room).

    Also if I forget to take the watch off when getting in the shower as I mentioned earlier, its not the end of the world as it has water resistant to 5 bar, which is enough protection in the shower.

    Love the retro style of this watch which is back in fashion with the teenagers. A must have for my soon to be 13 year old, who is hoping for this. Good quality and looks smart in the rose gold.

    Golden Review Award: 48 From Our UsersLovely looking watch. Looks a little more modern than the classic retro versions in yellow gold. Great value for money. Only negative (not really negative) thing I’d say is that I wouldn’t class the colour as “Rose Gold”. I have rose gold watches and rings and, in comparison, I would say they’re different colours completely. The watch is more of a dull bronze colour. Still lovely. Just not what I was expecting. It’s different. I like it, but some might not like the dullness. The strap is adjustable, and I’ve uploaded photographs to show this – you just snap open the clasp with a screwdriver and slide it up or down the bracelet, then close the clasp. Hope this helps. 🙂

    4.0 out of 5 stars Not sure I'd class it as rose gold...

    Love this watch so much, came early which is always a bonus! Was delivered on a Sunday – made my Sunday better! Love the colour and style! Great price, easy to adjust to fit my little wrist, catches my hair but oh well what watches don’t! Thank you!

    Bought as a gift for the wife… don’t actually know if she likes it yet as am waiting for christmas but she wanted a ‘retro style’ casio and I think this fits the bill. Good size for female wrist even though is listed as men’s. Would look a little miniature on my wrist I think. Very fast shipping by the seller and well packaged.

    Bought as a gift. Well received. Although the it says Men’s, it is not particularly big in comparison to many fashion watches. Was purchased for a female and looks good on a very small wrist.

    I bought this to replace my old plastic purple Casio when it broke as I wanted one that worked the same and it arrived in the proper packaging (contrasting to what some people have said in reviews) and looks lovely. I have had a lot of compliments on it and it is very feminine despite the larger size than some watches. However, despite it being advertised as Rose Gold it is definitely more of a bronze colour. Also it came much too big for my wrist and was very awkward to adjust even with instructions, but now adjusted it fits well and feels secure. Also, the buttons were slightly different to my old casio and aren’t as intuitive. Nevertheless the product was as advertised and looks good.

    his arrived very quickly. i knew it wouldn’t be an accurate rose gold colour as it states, because i had read previous reviews. this being said, i adore the copper/bronze colour. it is not too big for a woman, even though it is a mans watch, and i have quite dainty wrists.
    i’m really so happy with this watch as i feel it combines class with convenience.

    Came in the box, so you could tell it was brand new, no scratched or marks, still had the protective cover on. The colour of this watch is different from the rest, I love the frostiness on it and its better than the gold watch as the light is on for longer.

    I absolutely love this watch. Unlike other reviewers I think the size is perfect. The colour is really nice and the watch seems sturdy. However, after a week of use there is a small scratch on the glass. It’s not too bad and it’s only visible in certain lights, but I feel like I have been pretty careful with it, so I have knocked down one star.

    Overall I am very satisfied and would definitely purchase again.
