The 5514 is one of the most important Comex watches since it's the only that received it's own reference number for Comex alone. All other Comex wathces utilize normal Comex reference numbers i.e. 5513, 1665, 1680, etc. I was very lucky with this watch and was able to purchase it directly from the wife of the original owner. She included a nice letter with the watch and tons of dive logs, photos and other information. Serial 3,8xx,xxx.
