Corum Watch Admiral 42 Automatic A395/04043. One of the most identifiable characteristics of an Admiral timepiece is the use of 12 nautical pennants as hour markers. These flags in fact conform to the International Code of Signals for indicating numbers using colored flags, so each hour is represented by its corresponding pennant. The Admiral 42 collection proposed a family of elegant timepieces with a more modern and refined silhouette. The resulting 42 mm diameter variations, with a slimmer case diameter, has become one of CORUMs bestselling models over the recent years.
