Blancpain 2850B Leman Aqua Lung Grande Date SS Black Dial

Offered under the Blancpain Leman umbrella, the 2850B-1130-64B Leman Aqua Lung Grande Date was introduced in 2005 as a limited edition of just 2005 pieces, giving this sleek diver-inspired big date an immediate collector storyline. The case is brushed steel with a screw-down crown and back, maintaining true everyday practicality with a 100 m water-resistance rating. On the black dial, luminous indices and Arabic numerals frame a distinctive double date window at 6 oclock, delivering quick, graphic readability that collectors love on wrist. Power comes from the in-house Blancpain Calibre 6950 automatic movement, known for its finishing, reliability, and sporty-slim execution. The 6950 runs at 3 Hz with a 72-hour power reserve, backed by a 35-jewel architecture and the hallmarks of Blancpain bridge and rotor finishing. From a movement perspective, buyers gravitate to this model because it balances modern performance with the subtle complexity of a large-date display. At 40 mm across and an ultra-thin 11.4 mm profile, it wears with surprising elegance for a watch that borrows from dive aesthetics. For collectors, the combination of a black dial, tight limited-edition production, and the caliber 6950 pedigree makes the 2850B-1130-64B a particularly attractive centerpiece in any Blancpain Leman run. Excellent Condition with Blancpain box and papers dated 2007. Includes Blancpain service papers dated 2021.
