Job Number 260026

This one came back to me after a few years, suddenly not running at all. Oddly, it had no power on the escape wheel. Without complete disassembly, I found a tiny speck of something hard, possibly an almost invisible chip of glass or clear plastic, or maybe something else. The debris was jammed in the 3rd wheel pinion. It's ticking away fine now.

During 24 hour test runs I have been having a very hard time getting consistent results with this one. Back on the bench I figured out the the balance cock does not sit exactly flat and can rock front to back a little, almost imperceptibly, just from handling, causing irregularly excessive end-shake. 

It's not one of those where divots have been previously raised under the part either. It looks pristine. I flattened out what looked like irregularities, set it properly, and (carefully) tightened the screw a little extra. We'll see how it goes now.

Job Number 260024, The Geneva Stop Installed


Here's the Geneva Stop parts that install on the bottom of the barrel. The mechanism stops the spring just short of a full wind, and just short of being fully wound down so as to make the best use of the mid-section of the spring where the power is most consistent. 

As a practical matter this is really not something that would make a notable difference on a watch like this, especially today. Other factors will impact the rate over its runtime to a greater degree than the slight variations in the mainspring strength. 
As with everything in a watch, the key to installing the mechanism correctly is to understand how it works. The easiest way to do that is to carefully study it before it's disassembled.

For these, all of the leaves of the Geneva wheel are concave, except one. The cam can not pass the convex leaf. So with the mainspring at rest (unwound) the convex leaf goes just behind the cam that that the Geneva wheel will turn, as the watch winds, until the convex leaf comes around.

The install position also requires a small amount of tension on the spring to fit the cam. Thus fully run down, where the watch stops, is actually just short of the spring being fully relaxed.

Now here's something you don't see everyday... The barrel on this next watch has a fully intact Elgin Geneva Stop mechanism, with all the parts present. I've done hundreds of 18 size Elgins that had barrels with the cut-outs for these extra parts, but some or all of the parts missing. 

I suspect at some point Elgin stopped including this feature, even though they used barrels with the extra machining for awhile. But I also suspect in most cases watchmakers just didn't reinstall these parts when servicing the watch. Setting up the Geneva Stop correctly, so the watch winds to the desired point, is a little non-obvious. I'm sure many just didn't bother. Since it doesn't impact how the watch runs, not really anyway, their customer would never know the difference.

I drilled out the hole where the pin was sheared off, in the plate edge at 11:00, and fabricated a new post, friction fit.

This took a lot of by-hand cleaning, but it turned out well. Nothing broken, everything works.

Getting it properly in case will take some work yet.

Job Number 260022 - Before


The head of the case screw is broken. It was a pain to get out due in part to what looks like a bunch of glue having been applied in this area. It's not clear why. The plate screw near by also has glue on it, and in its slot. 

Plenty of dirt and old grease here...
The location pin in the edge of the movement is broken off. These older 18 size movement have just one case screw and this brass pin that goes into a hole in the edge of the case. This pin will need to be drilled out and replaced.

I did some straightening of the hands. You have to be extremely careful doing that with this type. Old steel is very brittle.

Tangential lever escapement...
This is one of those older 18 size Elgins with a very clever, but ultimately problematic, lever setting mechanism. There is often not enough strength is the spring to hold the ring against the cannon pinion in both directions.

It can be tricky to get one of these to work. 

Notice that his grade has both stem and key winding.

The yellowed plastic crystal on this on caused corrosion on the hands. I may be able to clean this up, we'll see. Other internal parts were OK.

Old formulations of plastics did this as they also turned themselves green, yellow or even sometimes blue. Modern watch crystal replacements, that aren't glass, are plexiglass and don't have this problem.

Job Number 260018, Spade and Whip

I am occasionally asked if hands like this are not original since they don't seem to match. There's no reason to think the watch was not purchased originally with an hour and minute set like this. They came from the factory with this style, called "spade and whip".

Wristwatch Conversions

Now and then I get an inquiry about a wristwatch conversion; a vintage pocketwatch movement in a modern wristwatch case. I used to occasionally service items like this, but I stopped long ago when I realized I'd just be replacing the balance staff every year. It's a poor use of new old stock parts the suppley of which won't last forever.

I don't want to sound harsh, I truly don't, people can do as they like with things they own. But I have to say I wish people wouldn't do this. Vintage pocketwatches and wristwatches are different. Pocketwatches were built to rest securely in a vest pocket and will not perform well swinging around on the end of an arm, to say nothing of getting broken by the first knock on the edge of a table. Vintage movements do not include features, invented later, that make practical daily use wristwatches as we think of them today.

The aside, I just don't get the appeal. Why? If you want a wristwatch, please just buy a wristwatch.

No problems.
So far, this is running better than these small one usually do.
