I have for sale a brand new Tissot T12 Stainless Steel Case which is still sealed in its original factory packaging. The model number of the watch it fits is the T082210A and the Tissot part no. is T300032999. It comes with the sapphire crystal already installed as well as the back gasket. It even has the pins and tubes needed to fit it to the bracelet.

Please feel free to ask any questions.
