Hi, There is a spring between the barrel and the gear that seats on the barrel. The spring shape is like a washer, but it is not flat – it is bent little as a cone. The junction is riveted, so no disassembling is intended… One possibility is that the junction is worn by too much turning, so the distance between barrel and gear has increased and the spring does not apply pressure any more. If so, press the gear towards barrel and try to rivet the junction by turning/rotating with some pressure a tool with ball shaped tip in the gap. Other possibility is the spring is broken and now it is too weak. In this case junction must be disassembled and a new spring must be cut and installed. But the parts may bend or get spoiled when breaking the riveting… This are cheap late Roskopf type watches, with no jewels or with only one… Many different manufacturers made them, after that Roskopf sold their patents…The parts are not interchangeable.

I needed 6 identical conical shape pocketwatch crowns. Decided to make them myself... That`s why I nnvented and built a copying device with fly cutter for my big lathe. Here is a video, that shows how it all works... https://youtu.be/1KQ8phy5vn8

Sorry, I wonder how is damaged the center wheel and is it really beyon repair... Can You show a picture? Omega.. They are good movements, but nothing special, just litle above midle class... Nothing to do with high quality class...

Probably this is FHF movement. But a look under the dial is what is needed for correct identification

To replace the whole lever - this is bad idea. As I said, the parts of this watches are not interchangeable. Esspecially the lever... Especially, when the original lever is here. Broken pivot is an easy to do repair. It usually takes no more than 30 minutes. Turning new axis - the same...

OK, the lathe is big. But, You can put in the jaws 3-4mm brass rod and make on the top of it conical hole, like a wax chuck. You can do it with hand-held graver. Then You can wax and center in it the broken ax and make the center for drilling with sharp graver... Then You need 0.3mm tungsten carbide drill bit, which can be hold by fingers while drilling the hole for repivoting. And then - to glue with threadlocker a piece of suitable guitar string in the hole...

There are no spare parts for this kind of watches, as parts from one will never fit to another, because they are made and finished individually. Your option is to repivot (drill a hole and fit another pivot) or make new axis. If You have a lathe, learn to use it. No matter how big it is, it is possible to do what is needed. All depends only on the skills of the latheman... And, it will be helpful to leatrn how to assemble this kond of watches... The pivots of the lever brreak when one doesn`t know the right way of assembling. The parts must be aranged on the upper plate, (the one without pillars), turned upside down, and then the plate with pillars is to cover all.

Yeah.. No need of thinking at all, an nothing to calculate... There is nothing to be done before You don`t have the right wheel. This is all You need, nothing more. No difference if the other parts or dial are original to the movement or not. The date wheel is good and You don`t need another. As it will be very hard or impossible to find suitable wheel, I can cut one for You and send it by post... But, please, show a picture of the front of the movement, without dial, so the gears are seen and the teeth can be counted, as we need to know the right number of teeth.

As I see, You made the wheel that is engaged with the hours wheel, and has a pin that turns days wheel… If the hours wheel has 32 teeth, then Your wheel should have 2x32= 64… 65 is no good number, as it is odd, not even… But, this is not the reason for which 2 days a switched ahead… The position of switching pin on Your wheel is wrong… You must move the pin a little away from the days wheel, and this will solve the switching problem. But still, the time of day changing will constantly move, because of the wrong teeth number…

If a mechanical watch is running without stopping, this still doesn`t mean that this watch is OK. Not even timekeeping shows the health of a watch… There is a parameter – Amplitude of the balance oscillations, that actually shows the condition of the watch. When the watch is OK, then amplitude should be 250-330 degrees, equal in both horizontal positions, and a little less, but again equal in all vertical positions. So, if somebody new to the world of watches, asks “Why my watch is stopping sometimes?” , the first thing that a watchmaker will ask, before give any answer, is “ And what is the amplitude???” If the amplitude id good, probably the watch will run with stability and no stops because of not enough energy coming to the balance will happen. If the amplitude is weak, then the watch may stop easily in many situations, and good timekeeping will be impossible to achieve… Weak amplitude means, that not enough energy comes to the balance from the mainspring thru transmition and escapement, or there are losses of energy in the balance itself… Not enough energy can be because of bad or dirty bearrings, worn pinions, weak mainspring, worn or badly adjusted escapement parts… Losses in the balance can be because of bed or dirty bearrings again, also bent hairspring, and improper collaboration with escapement… If and old watch, that have not been running from many years, will have to be brought to life again, the first thing to do is to disassemble it, clean all the parts from old hardened oil, and inspect all parts for signs of ware. If needed, some parts must be repaired, replaced, or made by the watchmaker if no replacement is possible… Then all must be assembled, oiled, regulated…

This is 'Le Phare', werry easy to recognise watches, by the speed regulator...

This movement is not german... and a litle bit older...

This is old "Tobias" type key wind movement. Thow it is quality made, it is probably old manufacture type, where on one street of the willage they cut the wheels, on another - pinions, ont third - they asssembled wheels and so... Almost hand made. Parts of one movement never fit to another... Probably will never understand who made it.

No, it doesn`t need any replacing. When the time is adjusted, one should feel some resonable resistence...The cannon pinion is like a clutch, when You adjust time it slips ower the center wheel axis. When it is loose, it needs to be tighten a litle. This is usually made by gentle pressing on the old mark with nail clipper. First You need to take off the cannon pinion. To avoid tightening it too much, they put inside some steel wire, or for example, a broach... Well, it is verry easy to break a cannon pinion, if there is no enough experience, so first You need to try on some movement that is only for training...Or You leave this to someone who has done it many times before...

Probably this happens because the cannon pinion is too loose. This way the watch may work all the time, but the hands may stay some time on place, especially when the date is to be changed. Usually this happens after long date adjustment, by turning hands by crown many days ahead to reach correct date…
