Kalbe is home to D. Dornblüth & Sohn, a small but highly respected German watch company. Most of their watches are what are referred to as "deck watches" or marine watches. They are considered by most to be high quality with large amounts of hand-finishing. Dornblüth could be called a connoisseurs brand. Although small, they do not fall among the ranks of many other small micro-brand watch companies, which oftentimes house inexpensive utilitarian movements.
