What size dome to order? Begin by measuring the dimensions of the items you intend to display. Note the width, height, and depth of each piece. This will give you a clear idea of the minimum interior dimensions required for your dome. Keep the scale and proportion in mind. Your glass dome should neither overpower your items nor appear too small for them. Ideally, there should be some visual balance between the dome and the displayed items. Style: Handcrafted glass domes can vary slightly in thickness and/or clarity which adds character to your display. Creative uses: Exhibit your pocket watches in glass domes to add style to your retail store display, home, or office. Our domes double as a personalized gift, interactive timepiece installation, or a decorative centerpiece, adding elegance and historical significance to any space.
