Sessions Tambour Mantel Clock Value Guide

The Sessions Tambour Mantel Clock, often called the 'Napoleon hat' due to its distinctive curved silhouette, represents a pinnacle of early 20th-century American horology.

What affects the value of Sessions Tambour Mantel Clock?

• Condition of the hardwood veneer, as cracks, peeling, or water damage significantly reduce the $150-$300 market value.
• The presence of the original winding key and the functional status of the half-hour or Westminster chimes.
• The material of the dial, with original brass or high-quality enamel faces commanding higher prices than paper replacements.
• Mechanical integrity, specifically whether the 8-day movement has been recently cleaned and oiled by a professional.

How to Identify Sessions Tambour Mantel Clock?

• Look for the 'Sessions' name printed on the enamel or brass dial, typically located near the center or bottom edge.
• Examine the rear access door to find the 8-day key-wind metal movement, often stamped with the Sessions Clock Co. logo and 'Forestville, Conn.'
• Identify the 'Napoleon hat' shape, characterized by a central hump that tapers down into a wide, flat wooden base.
• Check for two winding arbors on the dial face, which indicate the dual-function time and strike mechanism.
