What a great surprise, this model is fully lumed! The finishing is impeccable and the rubbber strap just works and fits into the overall aesthetic. For a big watch, it's not heavy and fits more like a 43mm because of the lighter strap. The sapphire crystal may be the watches best feature as it distorts the dial in the deepest way possible. This watch feels and looks like a 500mm dive beast and at 18mm thick, this won't be fitting under any shirt cuffs. Nice job Phylida!
