The initial model was introduced in 1982 as the FD-210, which had a grayscale five centimeter display. The device weighed around 650 grams, with a measurement of 87 x 198 x 33 millimeters. The device was sold in Japan with a price of 54,800 yen. Roughly two years later, in 1984, the device was introduced to Europe and North America.
Sony manufactured more than 65 models of the Watchman before its discontinuation in 2000. Upon the release of further models after the FD-210, the display size increased, and new features were introduced. The FD-3, introduced in 1987, had a built-in digital clock. The FD-30, introduced in 1984 had a built-in AM/FM Stereo radio. The FD-40/42/44/45 were among the largest Watchmen, utilizing a 4" CRT display. The FD-40 introduced a single composite A/V input. The FD-45, introduced in 1986, was water-resistant. In 1988/1989, the FDL 330S color Watchman TV/Monitor with LCD display was introduced. In 1990, the FDL-310, a Watchman with a color LCD display was introduced. The FD-280/285, made from 1990 to 1994, was the last Watchman to use a black and white CRT display. One of the last Watchmen was the FDL-22 introduced in 1998, which featured an ergonomic body which made it easier to hold, and introduced Sony's Straptenna, where the wrist strap served as the antenna.
