Waterbury Onyx Mantel Clock (possible No. 107) with Open Escapement "Star" Movement circa 1890
This clock is made by Waterbury and is part of the "Onyx" series and closely resembles the Onyx No. 107. The clock features an open Brocot escapement and the Waterbury "Star" movement. The Star movements were made with open escapements and also with escapements enclosed within the movement. The Star movements are well made but somewhat unusual in that the time section of the movement is on the left and the strike section is on the right (as viewed from the front of the clock). The strike controlling snail is between the movement plates and cannot be adjusted after the movement is assembled. The strike hammer is activated by the rack gathering pallet pins; this ensures that the strike hammer is always in correct sync and never requires adjustment during setup, but the design puts extra load on the gathering pallet assembly which must be securely set in place. Striking is on a coiled gong supported by a long steel rod attached to the wooden sounding board at the bottom of the clock. The movement is secured in place by two straps between the front and rear bezels as is found in many French clocks. The movement is removed through the bottom of the case. This is a well made clock but can be a little inconvenient to service and adjust, it is also very heavy..
