The links on the left will transport you to pages that detail the typical work performed in restoring various timepieces.

All work performed by Historic Timekeepers is warranted for a period of one year.  In order to provide such a warranty, we only do "complete" work,  taking no short cuts.  You can see examples not only of our finished products, but also of the methods we use to produce individual parts.

Currently, pages are online for: making a balance staffmaking a spring detent for a chronometer, making a replacement gear for a clock and making a bimetallic balance for a pocket chronometer.

We will not accept requests to "just change the mainspring" or such.  If a timepiece needs to be serviced, it needs complete servicing (see our Pricing Policy)  It needs to be completely torn down and each component inspected and renewed.  The only exception to this is our custom parts service, used primarily by other professionals.

For those who are interested, you can take a tour of my shop.  That page is provided for those who would like to assess my capabilities or are just curious about horological equipment and techniques.

If the work you require does not "fit" in one of these categories, use the information below to contact me.

ATTENTION!  This year I several received requests to make corrections to several aircraft clocks under warranty.  I would have done, except the work was not mine.  Apparently there is someone very active on eBay using a similar sounding business name and a website that is similar in layout to mine.  While I am flattered, this causes problems for those who use and or collect aircraft clocks.  Every piece I service is recorded in my invoicing system and is tagged with my service label, as well as the mainspring barrel is marked in pen with the date and location of where the mainspring was last serviced.  Also, you the customer will have an invoice/receipt from Historic Timekeepers, Inc.

I cannot be responsible for someone else's work.
