You must be confused. Very confused.
FYI there is NO such thing as 唔駛換電嘅 G-Shock/Baby-G. Such models use solar power and store power to the rechargable battery inside. The rechargable battery concerned does have a life span which, after very long use, will lose the ability to store power fully. When that happens the rechargable battery has to be replaced by the official distributor.
I suggest you first visit Javys' showroom in central and/or TST to get more understanding on the Tough Solar model range. After you clear up things a bit, you can go back to 信和 to buy what you want.
