This is a new 6497 movement watch I purchased ,it's running at +10 spd.. But I can only extract 2 of the case screws and the others are too stripped to move I'm using a Bergeon 1.6mm screwdriver..I don't know what else to do short of going for a refund ... Does anyone have any ideas ?  Thanks Lenny........

Is this a Chinese watch? Just curious why you wanted to remove the movement?
Sometime it's not the brand of tool that matters but how its shape bites on the cut of the screw, and how it's used.

Yea , I'm requesting one ... The dealer knows that the watch came with some bad screw's and had offered to order more screws from parnis. I thought with a new screwdriver I would be able to get them out.. It's a shame because it seems to be running +10spd in any position so it would of been a good watch ....

Oh right, you meant case back screws. Try this, with a different screwdriver, hold the watch from below on some wood and plastic, tap the screwdriver while rotating. Also for screws that are real tight like bracelet ones, use a screwdriver with a barrell handle.

BTW, movements in Parnis watches come with no oil, so whatever effort you make to regulate now, heaven knows how it will run after a while.

Doesn't  look like an easy refund .. I could use a dentist to see about the screwsssss.........I wonder if super glue on an old screwdriver would work ?

Have you given a try to the method explained above? All it takes is to find the right angle for the drive blade to bite. Keep the movement in the holder in a vice wile doing that.

Which type of screwdriver is the best ontop ...?  Don't know , these screws are like butter...

Any that you don't mind hitting onto and has as blade that bites into the screw. Otherwise bring it to a watchmaker to have screws removed.

I spoke to one yesterday , a real prick . He started out by saying I can't regulate it any more because  the needle was at the very end of the writing of  + &- on the balance cock .. then he said it will go out of beat if I regulate it and that the Chinese hammer in the screws...

He may have had a poor attitude, but he may have been right on all points, sorry to say. Before I didn't even noticed where the regulator was.

Yea , I was alarmed where it is also , but have seen pictures of the same movement with it in the same place .. I also showed the picture to the German guy who does the kits with this movement and he said "I can go farther"  I'm starting to think that the screws are hammered in lol....

@jdm: Is that a fact with the oiling of the asian 6497 or a statistic based on your observation

@Lenny & @jdm looking at the first picture in the thread I believe there is enough arc on the regulator the take out those 10 seconds.

Could have a fix, even repinning the hs to the end stud. But the matter is, when one buys something new and it comes like that, it's understandable that a professional doesn't want to deal with it. Because the high potential of unpaid time ending in frustration.

Well LmWatches UK kindly sent me the White Parnis power reserve and I got it dialed in to about +6 per day without using a timgrapher. If it had a fine tuning screw like the swan neck it would of been perfect but I'm pleased with this watch at the moment ...

      Rolex Cal 1570 Balance wheel rubbing

      By Jon · Posted

      Here's a quick Gif I made to show truing the balance using callipers. This has such a slight wobble, but is within acceptable parameters. The important thing is the balance doesn't touch or rub anything when in operation. This is an Eterna Tank. Here's a pic of the balance freshly rivetted with a new staff in the movement

      I just poked an inflation calculator, and $5 in 2020 would be about $6 in 2024. Doesn't fit very neatly into any status codes, which stop at 5XX, but that's honestly somewhat arbitrary outside of a clever pun for those that dabble in such things. Back during the pandemic, I would spend a good chunk of idle time in the evenings scanning through hundreds of listings a night, and I would only land 1-2 a week max. I would often go months without finding something suitable. A very small percentage of the watches in the price range are worth pulling the trigger on for my purposes. The number floating through the thread here may be somewhat deceptive.

      Balance cock stud screw

      By Zedster · Posted

      Hi, guys I got there in the end after several attempts using a screwdriver and Rodico, I couldn't wait for the tool to arrive and was getting pretty confident handling the stud screw without it flying away. At first, I was using far too much Rodico, and then realized you only need the smallest amount inside the screw slot. Putting the cock back onto the movement also helped as it gave me more to hold onto while my shaky hand tried to align the screw wobbling away at the end of the screwdriver😁 Anyway, job done and I can move on. Thanks again for all the advice it's really appreciated for a beginner.

      the escape wheel can't move itself

      By nevenbekriev · Posted

      You need to know at least the basics. Then the questions that You ask will begin to make sense. From what is seen on the video, the gear train and escapement look fine, but the balance doesn't rotate free. I can suppose that the thin gold colored shim that must stay under the balance cock is not in place.
