Design and Build
The Bosch 909 Dual S is lightweight and compact, measuring 122 x 50 x 17 mm and weighing 109 grams. This makes it quite portable, fitting easily into a pocket or small handbag. Its construction is typical of late 1990s technology, with a durable plastic finish. The phone uses a Mini-SIM, a standard for that era, maintaining a straightforward and robust design that was practical for its time. The monochrome graphic display with a 96 x 32 pixel resolution is modest, accommodating just 4x16 characters on the screen, which was sufficient for basic messaging and navigation.
