Timekeeping

The illustration on the left shows how the time is changed - the adjuster is pushed in to disengage the hands from the rest of the movement then rotated to set the time.

The timekeeping of these clocks can be altered by raising or lowering the pendulum bob (right illustration); they can keep time to within a few seconds per day . Timekeeping does drift with the seasons; central heating is an added factor. Clocks kept in stable climate-controlled environments keep excellent time over the long term.

These clocks have been designed with reliability in mind; they should run trouble-free for many years.

Mechanical clocks require maintenance. Yours should be returned to the workshop after about three years - I will dismantle and inspect it fully, clean all parts, replace any worn items, fit a new cord and re-oil the bearing surfaces. There is a charge for this service. I will repair (and possibly modify) any clock that just stops working for free.
