Extraordinary Tissot watch named Tissot Ceraten. It has this name because the case is made of ceramic and the battery is a 10-year lithium battery. Must say that it was quite something to replace the battery, because the case is a sealed case. Crown off the watch and pumping it; this went perfectly. Watch is now as good as new, with a new gasket. It is simply a gorgeous Swiss-made watch that runs perfectly. As such, it naturally has a gorgeously shiny ceramic case with a beautifully coloured dial. The watch is still in original condition and in very beautiful condition. It can now be used for at least another 10 years. Personally, I think this is 1 of the most beautiful - and at least the most extraordinary - Tissot watch made in years. But there's no accounting for taste, and perhaps you think this one is very beautiful as well. Anyway, it does run fantastically. Diameter is 26 mm. Length is 23 cm. Comes in the original Tissot box. Will be shipped registered and insured.
