Although the style has been around since the 40’s the past few years have seen a growth in the popularity in the Beobachtungs-Uhren (Nav. B-Uhr or Nav. B) watches. These were worn during WWII by pilots and had some specific guidelines for their design. They had to be large (normally 55mm) as as to be easy to read, and contain luminous paint so as to be legible at night. A large crown was required so as to be operated with gloves and a movement with a hacking seconds hand.
The watches from the 1940’s will run you well into the thousands of dollars, well above the budget of many a watchnerd. And the 55mm size makes them prohibitive for most wrist sizes. Fortunately a number of brands have come to our aide and provided a range of options for the watch enthusiast to consider when shopping for a watch in this iconic design.
