I no longer own this Skmei watch, but I had it for 5 years (or two battery changes). I even wore it occasionally.
I didn't wear this one a lot for reasons that I will now discuss.
I only bought it because I was on GearBest looking at computer games and this popped up in the top bar of other things I might be interested in. At only £5 at the time, I thought I'd give it a try. I also bought a red Casio 6900 Rescue clone with no branding for another £2, and I don't have that one either now.
The trouble was that this was in the early days of watch reviewers on YouTube (although some claim to have been at it a lot longer), and a bunch of American YouTubers all appeared to get wise to the joys of GearBest and these cheap G-Shock lookalikes at the same time. Some of them like "nutnfancy" loved them for the aesthetic and value, while others dismissed them as toys. The latter absolutely trashed them and anyone who would buy such a thing. I don't need to name names, but the "snobs" are some of the most hated YouTube watch reviewers to this day, if they even still have channels left.
Unfortunately, I started to notice quite a few problems with my "homage". Because of the glowing praise it was getting from the good reviewers, it made them even more disappointing, and I later discovered that I was not alone.
My problems with the Skmei 1029 began when I went to the corner shop and the manager asked me where I got my G-Shock as he'd just paid £145 for one. I explained that mine wasn't a G-Shock, it was a £5 Skmei from some internet site, and we both felt bad for each other. I couldn't believe that he paid £140 more for a watch which looked the same, and he couldn't believe that such things as my Skmei were even legal.
My second problem was that one morning just after the watch arrived, I went out into the cold from a warm house, and the screen immediately filled with condensation which then froze inside. I think from that you can tell that these watches aren't waterproof at all, or at the very least, it already had moist air trapped inside it.
Then the real trouble began when although the analogue portion of the watch kept perfect time, the digital LCD module was running 5 minutes or more fast every month. I kept resetting it, but it was a massive annoyance, and by then I'd already upgraded to another Skmei which I preferred anyway.
The size of this Skmei 1029 is, of course, almost identical to the Casio Rangemaster. The Skmei 1019 without the second analogue movement looks even more like the Rangemaster, but both are lighter. The plastic used is actually very much like that which the real Casios use (other brands such as Smael and Sanda use something different), but it's not quite the same. Seals and seams are pretty good considering that you can't trust the 50m water resistance because of the lack of quality control, and the strap is the same as any real Casio or third-party Casio replacement strap.
The display on the Skmei 1029 is very clear with good viewing angles through the plastic crystal (which I never even took the screen protector off because I didn't realise it had one on it), and the backlight is the same as Skmei use on everything, so it's better than any Casio at this price.
The straw which broke the camel's back for me was when I had to change the batteries. Taking the back off with the 4 little screws in each corner isn't difficult on this model compared to the later ones where you have to take the strap off first, but it was still fiddly. Inside, working out that there were 2 batteries to replace and you can't get to the smaller 377 without removing the 2025 and several stickers, was a nuisance. The 377s ran out of juice several times compared to the bigger battery, and are very difficult to remove.
The basic functions of the Skmei 1029 are the same as any cheap Casio, and it even sets the same way as a Casio F-91W. There are no advanced "Rangemaster" features, and to be fair, the details on the watch don't suggest any either.
The alarm isn't too bad on these, and the hourly chime is as annoyingly shrill as it should be. I didn't test the stopwatch function more than "start, stop, and reset" because why would I? If it had a countdown timer, I would have used it more.
At the time of purchase, I honestly didn't even know what a Rangemaster or a Mudman was because I had no interest in G-Shocks. I still find them very confusing and the number of different models overwhelming. I only bought this Skmei because it was cheap, I liked the colours, and I hadn't owned an "ana-digi" for decades.
In conclusion, the Skmei 1029 looks like a Rangemaster but has none of the good stuff which Casio offers, and the one I got had too many faults for me to ever recommend it even as a basic watch.
