Welcome to my website whose purpose
is to share my enthusiasm for preservation, restoration and collecting of specialized
timepieces as well as dissemination of information about them.

to get the drop down menus to go to each horological sub-category or
click on the pictures. Movie studios, TV film
crews - we rent props!
This website is divided into the three areas of horology that interest me. They are
tower clocks (also known as

bank vault time
locks. The common theme is the fact that one can see the mechanism. When
these clocks are running, they become beautiful kinetic pieces of art. This is especially
true at the scale demonstrated by the tower clocks.

beautiful kinetic sculpture. The
button goes through a typical restoration process for tower, skeleton and
time locks. One will get a sense of how labor intensive (labor of love?) this process can
I've written papers on tower clocks and the Westminster clock. A discussion on
remontoire along with visual aids can all be accessed through the Other Items button.
Below is a commission, to my design, to have a large,
complex astronomical clock built over the next several years; it was begun
in January 2006 and can be seen under the
