A. Lange and Söhne 1815 233.026

The A. Lange & Söhne reference 233.026 represents the 1815 Manual Wind collection in a 40mm white gold case configuration. This reference features a black dial paired with a dark blue alligator strap, distinguishing it from other variants within the 1815 series through its color combination and precious metal construction. The 40mm case is crafted in white gold with a smooth bezel and protected by sapphire crystal. The watch houses a manual-winding movement, requiring regular winding to maintain operation. The black dial provides contrast against the white gold case, while the dark blue alligator strap offers a complementary accent to the overall design. This reference was produced from 2005 to 2017, representing over a decade of availability within the collection. The combination of white gold construction, black dial, and manual-wind movement positions this piece for collectors seeking a dress watch with traditional mechanical operation. The 40mm case size accommodates contemporary preferences while maintaining the classical proportions associated with the 1815 series.
