Authentic vintage BIRKS brooch watch collectors

Gorgeous vintage BIRKS ~1930 Extremely rare piece. Swiss movement Gold watch brooch Glass face with diamond cut surround (I attempt to show this in pictures). With birks box Enamel accents floral and bow This is a rare piece. Fantastic vintage condition. This is a mechanical / wind up style time piece. It was working a few months ago and today is not - which usually means it needs to be demagnetized. That’s the great thing about wind up pieces, typically an easy fix. We do not live anywhere near a jeweller … I am told however that If they sit without use and stop working, the culprit is typically magnetic home items.
