Prisma

WE ONLY HAVE A FEW PRISMA GEAR TRAINS LEFT. WHICH MEANS FEW PRISMA’S LEFT. PRICES WILL CONTINUE TO INCREASE! NO EXCEPTIONS. PRICES ARE FIRM. $759 + SH & H

The Prisma TL has been designed to come close to the original Prisma from the 1970’s, but with the improvement of the large dual disk second hand and LED’s for the internal light source (no fluorescent lamps to replace) giving you more and better colors.  Most customers just order this standard version.   

Prisma Clock

Attention:  We have changed what is Standard (8/8/2019) The larger second hand disk is now Standard, and the smaller eccentric disk is Optional.  The reason for this change is customers irritation at the hour and/or minute hands becoming very hard to see for several minutes twice every hour.  It has been a problem even in the originals from the 1970’s.  The larger second hand disk’s rotation over the hour and minute hands means they are easier to see more of the time.  This also has the advantage of more color activity.  Enjoy!     

Special additions: If you would like to make any changes to the Prisma, you may do so. There is a flat $25 dollars for these conversions.
