Blancpain X Fathoms

Blancpain's Fifty Fathoms X Fathoms 5018 1230 64A is a titanium dive watch measuring 55.6 mm across and 24 mm thick. The black dial sits under a sapphire crystal and carries a central seconds display. Inside is the self-winding calibre 9918B, which stores 120 hours of power reserve, a figure well beyond most automatic movements in the collection. The case size makes clear this is built as an instrument rather than a dress piece. A rubber strap closes with a pin buckle. Titanium keeps the weight manageable given the case dimensions. Blancpain rates the case to 300 metres, in line with its dive-watch purpose.
