Waterford Crystal Large Dome Clock Missing Timepiece Stunning. For sale is this very large and significant dome mantle clock from Waterford Crystal. It is missing the timepiece but the size for the clock is a little over 2 5/8”. It stands a little over 6 1/4”. It’s a huge chunk of crystal and weights about 4.5lbs!! Other than the missing clock it’s in perfect condition. Very sparkly with lots of cuts. It catches a lot of light. It has the old Waterford mark and is even stamped “Ireland” on the bottom which is rare.
