A friend is trying to find some information on these his and hers Praesent's. Knowing nothing about vintages at all I thought I'd post it here. She's trying to have the watches restored as much as possible as a gift to her parent's 50th wedding anniversary. They bought it when they were still young but left it lying around neglected for some reason.

Original bracelets are long gone but she'd like to have the watches restored to the best degree possible...
Any info, help, advice, suggestions would be much appreciated.
