This week I have decided to feature another vintage Longines as they are such a pleasure to work on. This particular watch has a 9ct solid cold case and caseback, and it is powered by a Longines Calibre 284 movement. Very much like the Calibre 12.68Z I featured on the blog recently, this movement is from an era when Longines were very much at the high end of the market. The level of finish is very high.
