The Vintage Wrist Watch Company has dated this piece to the 1920s.
The movement is protected by an inner hinged cover which is engraved with the name Adolf Kirstein, Gluckstadt, 17.11.28.

The watch measures 47mm diameter excluding the winding crown and the loop. The watch has a galonne case which is 800 silver with rose gold wash highlights. There is some rubbing to the rose gold wash, and the odd mark. The remainder of the case is in reasonable condition for its age; there is an indentation to the back, together with some marks where the back has been opened at some stage. The case back hinges open to reveal the 800 silver mark (which is a lower purity than the standard 925 sterling silver), together with the Junghans star logo.

The plastic lens is in good condition.
The white enamel dial is signed Astra. Unfortunately it has sustained some damage in between numbers 1 and 2 and there is a hairline crack running between the centre and number 11. Charming stylised numbers, an outer minute track and very ornate hands (one is a different shade of gold so is probably a later replacement). The hands are initially set by way of the pin-set mechanism.
