Groovy Vintage Lumitime Model LT-11 Orange Display Mechanical Digital Clock. This clock looks to be early 1970's and is very retro vintage cool. The outer case is tan but appears to have darkened a little with age. Made in Japan by Tamura Time Corp.The clock always shows display motion with a groovy spinning wheel effect on the right side. The digits are mechanical (not electronic), and appear to be lighted with neon back lighting? I have not disassembled this c...lock to know for sure. Could also be regular lighting filtered orange to imitate a neon digital clock. The clock has been tested, and everything functions, and is in very nice condition. Overall clock dimensions are approx. 7.5" X 5" X 3". The idea of a mechanical clock from Japan suggests that this clock is probably from the very early 70's if not the late 60's. A cool time piece for the retro hipster.
