A. Lange & Söhne’s 1815 Chronograph Makes A Black & White Appearance

The 1815 watch family just welcomed its latest member, an 1815 Chronograph featuring a black dial with a pulsimeter scale in a white-gold case. The new timepiece has a strong, well defined personality, characterized by a striking contrasts between light and dark, black and white. The black alligator leather strap, while the complete opposite of the case’s color, completes the elegant white-gold case and is safely fastened with a solid white-gold Lange prong buckle.

The calibre L951.5 movement powers this 1815 Chronograph in its 39.5mm case. Fear not the effect of a full black dial though; the rhodiumed hands and markers ensure flawless legibility, and won’t cause any time loss. A special function of the piece is provided by the pulsimeter scale -on the outer ring of the dial- which determines heart rates. Graduated from 40 to 200 beats, the peripheral scale indicates the heart rate per minute when the time for 30 beats is measured.

The sapphire-crystal caseback reveals the captivating architecture and finishing of the chronograph movement, providing a glimpse of the complex switching sequences, the column wheel that controls the chronograph, the levers of the flyback mechanism, the snail of the jumping minute counter, and the escapement. The staple Lange whiplash spring of the precision beat-adjustment system remains true to the brand’s style and design.
