I personally think you should’ve taken the original screw and made a longer one just like it. Anyone with a lathe and a few minutes of time could make you one with the right threads and everything.
Certainly not anyone, this screw is so small you can barely see the slot for the screwdriver with your eyes. It would be impossible to single point cut, and good luck finding machinist with die for M0.5 thread or whatever that is.
I had this same issue with mine. Adjuster al the way in, and still running fast. I found that I had to de-magnetize it, but still no change in rate. So I removed the swan neck, and adjusted it the old way. now it runs dead on to +1 a day.
I’ve always wanted to see a video of an attempt at trying to regulate this very well known movement to see if its accuracy could be improved. Thanks for posting this.
Any movement can be more or less easily regulated as long as the end of the oscillating part of the hairspring is held in place by an additional part that can rotate around the shock absorber to change the speed of one oscillation. I'd even argue that the longer endpiece being held in place by the swan neck is easier to adjust on its own due to the length increasing the leverage when compared to other kinds of this regulatory system, making fine adjustments comparatively easier. Seiko movements for example have this lever a lot shorter, making it harder to make finer adjustments without going too far in the other direction by accident.
I opted to avoid the swan neck fine regulator on this movement as it is really not a movement that benefits from such a fine adjustment mechanism given its general build quality and finishing. working with the regulator pin positions is made easier without the faff of the swan neck and will achieve a reasonable outcome on my timegrapher
This could be true if the swan neck and swan neck screw didn't push on the lever from both sides, locking it firmly in place and making any adjustments in the desired direction impossible without either completely removing the swan neck or modifying it or the screw. Putting the regulator in the center won't guarantee any kind of accuracy since the factory tolerances simply CAN'T be tight enough to make this middle position work for every movement.
@@alvarojoseborreror.6588 Sorry but I'm not a watchmaker, so I cannot provide any qualified advice. But if I really had to do it, I would risk scrapping the watch by pulling the hand off and pressing it back on in the zero position. These things are so cheap that they are not worth repairing unless you are doing it just for fun.
A misalignment can occur from regular use if the reset of the seconds hand is done close to the 30 second marker which increases the velocity at which it returns to the default position, thereby basically slapping itself out of place. You can try resetting it closer to the end of the minute to try gently nudging it in the other direction again and if that doesn't work then someone with experience setting watch hands should take out the movement, remove the seconds hand and put it back in the right way. Hope this helps!
Almost all my quartz watches are stopped. Batteries has died, but mechanical watches i can pull out any time and ready to wear. The one kinetic seiko is still alive 😊
@aleksandrorlov1515 It is true that batteries die of course. It's not super difficult to replace them, plenty of vids on UA-cam. All my solar quartz watches are still working fine, some after 15 years. 😀
Probably cheaper to buy another one than have a watchmaker repair it, but there are hundreds of videos on very low cost time graphers and watch regulation. You may have found a new hobby. Or, just buy watches that are worth more than your car. You don't drop them EVER. Ask me how I know.
This unwittingly illustrates the problem with these watches/brands. You shouldn't have had to modify the adjusting screw if the thing had been made properly in the first place. I had a homage watch with this movement and the winding mechanism broke after 6 months. These watches get rave reviews but there are q c issues.
It very knowingly illustrates that these movements are not to be regarded as quality movements in any respect. With new ST1901 movements available at around 100 $/£/€ you're going to get the quality and quality control that you've paid for. Any mechanical chronograph at less the 1k $/£/€ would be 'workhorse' quality at best. Seagull et al are nothing more that novelties with curiosity value to play about with.
♻ sell it for parts or repair : parts are hard to find on ST19 ... so i'm searching for such non working ones (🇫🇷 ) repair of the winding mechanism (click spring) is also a common issue on old ST19 i had (2 by now had this issue)
Oh no, it doesn't cost five times as much for a second line of text on the dial, no display caseback and an acrylic crystal instead of sapphire, so sad 😭 You also get extra points deducted for writing Seagull instead of Sea-Gull

Rubber ball opens all this style back in my experience.

Great video! Very impressive machining skills!
Great video mate. I love the, oops i don't have a tool, so i will just make one moment.
Cheers. All I ever seem to make is more tools, though.
It is a pleasure to watch. Good video.
very nice job - very inspiring 😊
Very interesting. Good job

It looks like paying extra money for swan neck version is waste.😅
Well said 👍
Swan neck pretty, though :)
@@LucaTheStar That is very true.
Werent you able to open it with the Rubberball Bergeon 8008?
I was thinking the same thing
You simple have to put the regulator at center, regulate with the lever, and then make the fine adjustment with the screw.

♻ still searching & byuing them in NON-WORKING conditon, for parts or repair : i'm a beginner on chronographs ♻
Hello my friend. I have a question, if the large seconds hand of the chronograph is not on zero position, how do I adjust it to its position again?

15 seconds a day is fine for a mechanical movement.
If you want better accuracy .
Very fiddly and maxed out from the factory to boot! No wonder people buy so many quartz. 😮

Cool
Mine is Running 8 minutes fast since I accidentally dropped it😢15 seconds would be Dream

I would’ve kept it cleaner.
Tus habilidades de relojero no son muy buenas parece. Con una simple pelota de goma habrías hecho el trabajo.
This is a fake Seagull.
By that logic all Seagulls are fake, do your research pal 😅
Oh no, it doesn't cost five times as much for a second line of text on the dial, no display caseback and an acrylic crystal instead of sapphire, so sad 😭
