[When you're excited. wicca] A limited edition model with a replacement band with a retro classic fashion taste. This is a solar tech radio clock with a small size (case diameter 25.5mm). Comes with a basic ivory band and a mature khaki band that you can change out yourself. Since it's a radio clock, the time is always accurate. There is no need to set the time because it catches standard radio waves and automatically adjusts the time to the correct time. [Retro Classical] The Arabic numeral font has a retro feel and is finished in dark colors to improve visibility and emphasize the classical look. Teardrop-shaped parts that look like swinging accessories are set at the 1, 5, 7, and 11 o'clock positions. The center of the dial features a pattern inspired by a classic chain bag. The limited edition model, which comes with the basic ivory ``ECOPET(R)'' band, comes with a mature-looking khaki replacement band.
