I have a Levin lathe that was missing a handle - that was today's little project and I thought I'd post some photos. The blank is small, .220" dia and less than an inch long. I turned the press fit section in big lathe then switch to a Pultra and did the balance by hand with a graver. Fun work, sort of like wood turning. The one I made is on the right, obviously not identical, but good enough for an eyeball job

Many oils have suggested shelf life of 6 years when they are bought new. Then again it is suggested that watches should be serviced every 6 years so. My question is: If a watch is serviced with a brand new oils... OR ...With oils that are near their recommended shelf life Could one expect there to be a significant difference in the performance of the watch? I mean, in theory, the oils are either 6 or 12 years old at the time of the next service. Let’s assume that the oils have been properly stored

Looks to be external thread on both diameters of the tube, with an internal gasket. The crown contains a face seal gasket. I've attached some more photos. Needs a good scrub. Sent from my SM-G920V using Tapatalk

Thanks guys. I haven't decided if I'll "take a punt".... The price isn't as high as a functional one but not as low as 50$...

Yes calibre 290 no date calibre 291 addition of date at either 12 o'clock or at 3 o'clock

What I’ve found out on the net is most parts will fit each other. I think you are in luck.

Is the 290 post the same as the 291. I now where you can find one. Send me a PM and i can give you the contact.

When the alarm goes off, it only goes off the once. Then fit all the hands to 12, doing it this way you will know the hands are aligned correctly to the numbers on the dial. Re set the alarm hand to 3, wind the alarm spring up, set the hands to 3 and the alarm should go off. Repeat this until you are satisfied the alarm is correctly working. If the alarm goes off before the hour then you need to adjust the spring that stops the hammer a little more.

You need to find out if the parts are Interchangeable.

no that part is a calibre 505, 1496 and will not fit you need the one specific to the calibre 291

The part it needs is a cal 291 1496 rotor post it is a separate part to the plate it is listed on the cousins web site as obsolete

As I explained you need the whole plate.

The axel has broken. The oscillating weight is held onto the axel by a clip, when pushed the weight is free to remove from the axel. The axel is fixed on a plate by two tiny screws underneath. You will need the whole plate.

This looks like someone filled some plastic containers with Mobile oil and printed some labels. No way any company label a product like this ebay stuff. Sent from my iPhone using Tapatalk Pro

Geo you could be correct, however the original post is not specific as to where it is worn to be 100% sure it is possible. Personally I think it is just not worth the risk & time required so I would just change it (if I could find a replacement that is)

I do agree that the cap jewel should be replaced, but if the jewel is set in an incabloc type of fitting, you could get away with lapping out the blemish and polishing the jewel. I say this because the the jewel will be held down by the incabloc spring ensuring that the jewel is seated correctly in the setting. This in turn will ensure that the original end end float is maintained.

If it is just the post it should be possible to make one, if you have a lathe that is !!!

No the post sits directly in the middle of the movement and is not part or the rotor itself. If the watch is very cheap I would take a punt and factor in the cost of a donor movement if its only slightly cheaper than a runner walk away.

It's a real pity because looking the movement it is in really good condition apart from the screw or post has been broken. The 291 is obsolete so its up for sale.

The jewel should be changed. After grinding the pivot fitting will be incorrect. If you require diamond powder (mix with oil) I use Bergeon with 3 different grades & I purchased from Cousins.

Yes the post is a separate part that is secured with two screws from the under side of the bridge, why not ask for clarification from the seller as to what part is missing or broken if its just one of the screws that holds the rotor post in place it should be easy enough to find a suitable one to use but if it is the post that broken then you will have trouble finding one as you say the way to go would be a donor movement but that may start to make the good price look a little less appealing

It is a calibre 291 the rotor sits on a post at the centre of the movement and the screw on the rotor is used to secure it to the post. It is probably the rotor post that has broken, these are listed as obsolete on the cousins web site, it is a common problem with this movement I dont know if any other supplier would hold this particular part. The ring looks like a tension ring from a watch crystal and is not a part of the movement such as a movement spacer ring as this one is held in place with clamps

Do not use naphta at all, it may explode (if it is what we in Germany call 'Benzin')! I use Elma 9:1 myself and I am satisfied with the results. 2nd jar destillated water, 3rd jar Isopropanol. Frank
