Blancpain Fifty Fathoms 500 Fathoms GMT 50021-12B30-52B

The Blancpain 500 Fathoms GMT is the serious, big-brother deep diver in the Fifty Fathoms family — a limited edition that takes Blancpain's iconic dive watch DNA and pushes it into true professional-tool territory with a 1,000 m–rated case and dual-time GMT functionality.
As a limited release, it's the kind of piece that quietly trades hands among serious Fifty Fathoms collectors who want the bigger, more capable expression of the line.


The titanium 500 Fathoms case carries the unmistakable Fifty Fathoms design language scaled up for deep-dive performance, paired with a sapphire-topped unidirectional dive bezel for legibility and durability under any conditions. The dial is set up for true travel-watch use with a clear GMT hand for second time-zone tracking alongside the standard dive-watch hour markers and luminous treatment, keeping the layout highly legible whether you're underwater or in transit. Powering the watch is Blancpain's automatic GMT movement, delivering the everyday reliability and finishing collectors expect from the Fifty Fathoms platform.


This example is in very good condition and comes with the original box and papers.
