European Excelsa pocket watch

Here is a pocket watch I would like to show to you all. It's a Swiss Excelsa watch with a cilinder escapement.
A college from my work owns it and asked me if I could restore it. It was all brown an dirty and the hands & glass were missing. The watch worked but only when I held it in a certain position.

I cleaned it, oiled it properly and now she's running like new. I bought a new pair of hands and made them on to the watch.
On the back is an agricultural engraving. My college is 69 years old and this watch belonged to his grandfather. Tomorrow I'm gonna take it with me to work and hand it over to him. Hope he's gonna like it.
