Zenith Electric Master Clock Service

Zenith Electric Master Clock Service

If you’re here you probably know that in the 20th century Zenith made some brilliant watches, but did you know they also made clocks? Recently I serviced this electromechanical clock which is part of the collection here at The Clockworks, where I am based. It is a weight-driven mechanical deadbeat regulator with a feraris motor to keep it wound.

James McCabe Bracket Clock Service

James McCabe Bracket Clock Service

I’ve recently been working on this lovely bracket clock by James McCabe. It was brought to me because of a problem with the striking mechanism - when wound the clock would strike continuously until it ran out of power. There are a number of things that could cause this but it was agreed that the clock would also be serviced while it was in the workshop, as it was evident that there was a lot of very dark oil and wear which could be seen simply by looking at the backplate.

Smiths Mystery Clock Repair: Hour Wheel Manufacture

Smiths Mystery Clock Repair: Hour Wheel Manufacture

Generally in clocks if you need a new part, it needs to be made. It’s much rarer in a clock, however, that those parts are barely larger than those in a watch. I was given a Smiths mystery clock which had a damaged hour wheel and had sat on the shelf in another workshop without any work being done for some time. Time to bring this interesting object back to life!

Recently a good friend, Neil, was visiting the workshop and wearing a very cool watch. A vintage electric Whittnaur with a very early movement. So early this uses mechanical contacts to control an electromagnet rather than the more common transistor. A great piece of history but also an amazing looking watch, check out the dial and hands at the bottom of this post.

Timing Washers - Large Adjustments to Watch Timekeeping

Timing Washers - Large Adjustments to Watch Timekeeping

Sometimes the timekeeping of a watch will be very wrong even after a service - several minutes a day. If a watch is gaining a large amount of time, there is a solution - ‘Timing Washers’. These are minuscule and precisely manufactured amounts of material, designed to be added in pairs to timing screws of particular sizes of balances to affect the rate a known amount (usually 1, 2 or 3 minutes per day).

Stowa Necklace Watch

Stowa Necklace Watch

This lovely watch was inherited by the owner from a grandparent and stopped working after it was dropped - unusual for a watch with incabloc shock settings but not impossible. Upon further inspection, it was found that a previous ‘repairer’ (or watchbreaker) had solved a problem of broken dial feet by simply gluing on the dial. The glue got into the incabloc and the watch stopped being shock resistant, leading to a broken balance pivot. New dial feet need to be properly fitted, as well as the watch being serviced and the balance staff replaced.

Wristwatch Movement Ring

Wristwatch Movement Ring

I recently had an enquiry from a customer who was worried a watch they had bought was waterlogged and rusty inside - not an uncommon problem, unfortunately! Fortunately this was not the case, and the movement and dial were both in good condition - the problem instead was the movement ring was incorrect and too small to support the movement, and so the last ‘repairer’ (or watchbreaker) had glued the movement into the case and this was visible through the glass. Digging this out to release the movement was a laborious task and new movement ring would need to be made to hold everything in place correctly. As you’ll see this is not just a simple ring shape!
