Alsal are an approved Junghans service centre and use original parts. They've fully serviced a couple of my Junghans and conducted a few repairs and their work has been perfect every time.
As @umop3pisdn says, polywatch and other polishing compounds don't work on the Junghans acrylic as it has a really tough chemical hardening treatment.
