This watch, on the other hand, is the first Speedmaster Chronoscope as well as the first meaningful design upgrade of a Speedy in a long, long time. I like to think of link it as the Ring of Power for all other Speedmasters. One link watch to rule them all, one watch to bind them, one watch to bring them all, and in the darkness … um … time link them.

The design and technical principles of the original 1953 Fifty Fathoms laid the groundwork for the ISO 6425 standard which link now governs whether or not a watch is suitable for professional diving and yet the link Fifty Fathoms collection laid mostly dormant for decades. Since 2007 however Blancpain has made up for lost time. The current selection of Fifty Fathoms watches is more diverse and accessible than link at any other point in its history.
