Mile Hi Clock Supplies

Mile Hi Clock Supplies have been servicing clockmakers needs since 1986.

Established by Emery Brittenham as Keystone LTD, founder of the Keystone product line. Since then we have added the Clockmaker's Keystone Depthing Tool and refined the Keystone Bushing and Mainspring Winder. Our product line has also been expanded to include more materials and hand tools for the serious clockmaker. Our catalogue is now more complete and easy to use.

We are located in the heart of the Rocky Mountain region, just north of Denver, Colorado U.S.A.

If you need information about any clock related item, or tool, please feel free to call, fax, or e-mail us.
