Antique Seth Thomas Adamantime No 102A Green Mareblite Wood & Brass Mantel Clock W/ Key. Very nice solid antique shape. Shows normal wear and age. Has some light scuffing. Marbelite does have some minor loss in one spot, and has some cracking as shown; but overall looks very good for its age. It appears to be in good working order, but it should probably be serviced soon if it’s going to run continuously. There will be a key included. It displays very well. Measures roughly 12.75×11.75×5.5. See pictures to make your own determination on physical condition.

However we can’t guarantee functionality.

There’s a good label on the rear and the clock seems to retain most of its original parts. Mechanically, the clock ticks and I got it to chime, but it’s probably going to require an adjustment or cleaning. The function seems slow. This is a great lookin clock and priced […]
