This vintage Sheffield alarm clock is a charming piece that will add character to any room. Made of clear lucite, it features a square shape and an analog display type. The clock is signed by the brand and is an original piece from the mid-20th century. The clock is mechanical and has a wind-up feature and is jeweled. It measures 1.5" in length, 2.75" in width, and 2.75" in height. The frame material is also lucite, and the finish is clear. The clock was made in Germany and is in good working order but it does have wear due to age and use. It would make a great addition to any collection of decorative collectibles. look carefully at the photos and message me with any questions prior to purchasing.
