Regulating a Seagull 1963 (Calibre ST1901)

[@johnathonmullis4234]

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.

[@miro6138]

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.

Rubber ball opens all this style back in my experience.

[@valengreymoon5623]

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.

Great video! Very impressive machining skills!

[@aleksandrorlov1515]

It is a pleasure to watch. Good video.

[@rafaelfranciulli]

You simple have to put the regulator at center, regulate with the lever, and then make the fine adjustment with the screw.

[@thejohnson9204]

Great video mate. I love the, oops i don't have a tool, so i will just make one moment.

[@TomIreson]

Cheers. All I ever seem to make is more tools, though.

[@fxhood2114]

very nice job - very inspiring 😊

[@tommusikauswahl1066]

Werent you able to open it with the Rubberball Bergeon 8008?

[@simartnullnet]

I was thinking the same thing

[@jollyrogers7666]

Very interesting. Good job

[@jackburtonstwin]

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

[@CorkBouldering]

It looks like paying extra money for swan neck version is waste.😅

[@neilpiper9889]

15 seconds a day is fine for a mechanical movement. If you want better accuracy .

♻ still searching & byuing them in NON-WORKING conditon, for parts or repair : i'm a beginner on chronographs ♻

[@williamvun]

Cool

[@roadgent7921]

Very fiddly and maxed out from the factory to boot! No wonder people buy so many quartz. 😮

[@aleksandrorlov1515]

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 😊

[@roadgent7921]

@aleksandrorlov1515 It is true that batteries die of course. It's not super difficult to replace them, plenty of vids on KZbin. All my solar quartz watches are still working fine, some after 15 years. 😀

[@MichaelWilliams-mo1vv]

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.

[@TomIreson]

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.

[@SQueme]

♻ 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)

[@philippkaltenleitner7861]

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

[@TomIreson]

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.

[@SQueme]

♻ sell it for parts or repair : parts are hard to find on ST19 ... so i'm searching for such non working ones (🇫🇷 ) bend pivot ? hair spring tangled ?

[@bricesuire5072]

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.
