Hi there,

I've discovered a passion for "clockwork" wind up clocks - I currently have a Minuette branded float balance type that is loosing time.

My other clocks I can adjust using a small screw or adjusting the pendulum.

On the body internally is marked "+" and "-", close to two screws (however these screws just loosen the balance wheel mechanism)

There are also two "butterfly" type things above the markings.

If anyone out there has any clues to how to do this, I can post some pics later tonight.

Help please :-)

No promises, but I know a guy with a large clock collection who might have a clue. If you want to post some pictures I will run it past him when the occasion allows.

Thanks for that offer.

Here's a quick look at the clock:

And I've got a few more photos here: www.online.geek.nz/clock/

Thanks again!

Doesn't that adjust the spring tension (drag) on the escape/balance wheel, which alters the speed of the movement and thus the time?

Unfortunately not - those screws are definitely holding the mechanism in physically :-(

Huzzah!

I believe I have found an answer - time will tell if I've got it right!

In case anyone else stumbles on this:

You need to "hold" the balance wheel still - on the top is a "spider" - you need to shift that in the direction of the + to speed up the clock, to the left to slow it down. This alters the length hairspring.

Onwards and upwards!
