A. Lange & Söhne is announcing a new collection that updates their Lange 1, Lange 1 Daymatic, Saxonia, and the Saxonia Automatic with deep blue dials, white gold cases, and hand-stitched dark blue alligator leather straps with white gold prong buckles.
Alongside the Blue Series of watches is their new 1815 Rattrapante Perpetual Calendar Handwerkskunst. The watch is their sixth Handwerkskunst and features a 631-piece movement that features a split-seconds chronograph, perpetual calendar complication with day, date, month, moon-phase, and leap year.
Its most incredible detail is the blue enamelled white gold dial that's detailed with relief-engraved stars. It also features a hinged cuvette engraved with the mythical goddess Luna, which can be lifted to reveal the movement. This is all wrapped in a 41.9mm white gold case on a blue-gray alligator strap with a white gold deployant buckle.
