LUMICHRON SKELETAL & MARKER CLOCKS

VIEW OUR SKELETAL CLOCK DATA SHEET

A LUMICHRON Basic Skeletal clock features hands and hour markers (or numbers) only, mounted directly to a building fascia or wall and without a surrounding case. The exposed clock face requires the clock movement to be mounted on the inside of the wall. If that is not accessible, then the movement can be mounted in an opening on the front of the wall, with an escutcheon plate to cover the opening. We call this a Rosette Skeletal Clock. Skeletal with Background Dial features the markers and hands on an added dial element (or choose a case clock).

Your dial and hand selection for a wall clock such as this will partly be determined by the size of the clock and whether or not you would like these elements illuminated. Size is always the outside diameter, measuring from the top of the 12 (or the top of the index at the 12:00 position) to the bottom of the 6 (or the bottom of the index at the 6:00 position). Don’t confuse with radius measurement which is only half the clock face!

The different types of skeletal clocks are on the illustration (right). Illumination for skeletal clocks is achieved with LED halo or front lighting on each hand and dial element (numbers or markers). At Lumichron we build these illuminated elements with polycarbonate covers, for durability and long life.

Skeletal called are sometimes called silhouette, or marker clocks)

All tower, building, architectural, and outdoor clocks manufactured by LUMICHRON are completely automatic for hands-free operation. The clock’s time is managed by a clock controller. The controller (basically a small computer) keeps track of time with a quartz-crystal and lithium battery and is often synchronized with a GPS antenna for absolute time accuracy with NIST.

For a fully illuminated background, please refer to our “fully-enclosed” canister and case clocks.

Benefits of Skeletal Clocks

Because of the relatively simple construction of a skeletal clock,
there are very few size limitations – they can be as large as you like, but generally no smaller than 24” with some limitation. Skeletal clocks provide a modern and practical aesthetic to your existing or new structure.

Features of Skeletal Clocks

Hands and Hour Indexes only
Optional background dial
Standard installation of the motor/movement is on the inside of the wall
Alternative installation of the motor/movement placement is front-access with escutcheon plate (depends on access at your site)
Custom built to your size specifications, with a range from 36” – 240”, outside diameter
All elements can be halo-illuminated (back-lit) which requires complete rear service or background dial to accommodate wiring
Time required for installation varies depending on your site and the type of skeletal clock you choose.
