Sky Watcher Tourbillon Table Clock Wooden Craft Kit

With a nod to Isaac Newton, we present the Sky Watcher Tourbillon Table Clock, a fascinating combination of the imaginative celestial observatory and functional table clock! The standout feature of this functional and beautiful wooden model table clock is the rotating tourbillon that sits on top. In wrist and pocket watches a tourbillon mechanism helps increase accuracy by counteracting the effects of gravity when the watch is stationary. By seating the escape and balance wheel within a rotating cage, slight errors in timekeeping introduced by the force of gravity are averaged out. In table clocks and wall-mounted clocks, a tourbillon often serves a more decorative purpose. This is true of the Sky Watcher Tourbillon Table Clock from UGears, where the sphere of the tourbillon has been styled to resemble a large telescope observatory scanning the celestial sphere, like those at Mauna Kea in Hawaii. The Sky Watcher tourbillon mechanism has three axes of rotation: around the vertical axis of the clock, the horizontal axis of the clock, and relative to the central axis of the inner sphere. The wind-up clock operates based on the accumulation of potential energy in a flat spring and the metered release of this energy. When the model is fully wound it can power the timepiece for approximately 2-3 hours, sufficient for long observation of the mesmerizing mechanism, or to provide a pleasant background ticking clock sound and visual diversion for a period of work or rest. Rather than an all-too-common clock face with hands, we have created additional interest by having the time display placed on reels. The minute reel rotates smoothly with the progress of the tourbillon, while the hour reel marks the passage of time with a percussive mechanism Features: Wooden Model Kit Self-Assembly No Glue Required Specifications: Model size: 12 x 7.1 x 6.5 in Package size: 14.9 x 6.7 x 1.8 in Number of parts: 338 Level: Hard Assembly Time: 15 hours Recommended Age: 14+ Kit weight: 2.71 lbs What’s Included: Laser Cut Plywood Boards Manual Wax Sandpaper Spring Shipping / Billing Information This product ships direct from the manufacturer: Your order will ship in approximately 5 business days.
