A restrained sport watch in Blancpain's Leman line, this Aqua Lung Grande Date balances the collection's polished sensibility with a more purposeful black-dial configuration. The stainless steel 40mm case and clean dial keep the look crisp and understated, with the large date adding useful visual weight without clutter. Its automatic movement suits the watch's everyday character. At 11.4mm thick, it wears with compact, easy proportion on the wrist.
