Today, in anothe place I found this 7 jewels clock in much better condition for slightly more(RMB 40 only). This is the collector's mentality that I want that item still missing from my collection.:-D It has the same case as that of the 15 jewels clock, but it has a nicer dial with big luminous hands. This should be an earlier product of Diamond travel clock.
The movement appears to be bigger than the 15 jewels. The cases have many colours and designs, perhaps another reason to collect some more? These travel clocks are just a bit bigger than some big pocket watches.
