In my skemi 1155 watch show only 10s how to solve it please tell me

Go on Ebay and buy yourself a 'spring-bar tool'. It has a tiny forked tip (2-prongs) that fits around the end of the 'pin' that holds the spring-bar to the watch--push down and lever it out, and your watchband will come off. They're only a coupla bucks.

There are many models of Skemi watch.

there is also a Contact form.

go to this link and i think its the second one down for the manual if its not just scroll down the page and see if you find one... watch manual for Skmei 1268 Google Search

On a different Skmei model, you can toggle the 12/24 settings within alarm settings. This also changes the setting for displayed time.
As I suspect that a lot of their models use the same internal module, it's worth a try.

Click on my profile (escapement), then click on Tips and Tricks. There you will find link to all CASIO watch manuals. Rate me, please.

Your watch is fitted with chronograph movement 5040D made by Ronda (Switzerland). If you take a closer look, then you will realise that the subdial at 3 o'clock is counting seconds allready. This is your seconds dial, not the big one.
The big seconds hand actually is the chronograph hand (stopwatch) and, when activated, works together with 1/10th counter.
Follow this link and see for yourself:
