SORNA is a SWISS-based brand that dominated the 1970s with its motor sports-inspired watches.
After the quartz shock, the brand went on hiatus in the 1990s, but has now completed a reissue based on materials from that time.
The T21707 is a casual model with a sporty large case and colourful dial.
Based on the model that was a hit in the 1970s, it has been reissued as a modern model with a calendar mechanism and automatic movement, while retaining a vintage feel.
