Open face watch case is made of white metal. Front and back are screwed. Back cover is marked SILVERODE with “crown” logo and a number. Movement is signed as “No. 102”
Watch is in very good condition. Chronograph and quarter repeater work properly. Movement works strong but goes too slow, it would benefit form cleaning. Dial has a hairline crack from 9 to 3 and a repaired chip, which is barely visible when front cover is on.
