Hello Forum

I am trying to disassemble this watch and after removing the stem and crown, as well as the two screws holding the movement, am struggling to remove the movement ring, which is holding the movement.

The movement (and dial) are freely moving in a circular way but if I understand correctly I need to remove the movement ring in order to extract the movement - however this ring seems really "stuck" to the case and impossible to remove it ... any advice or suggestions are most welcome! :)

I'm attaching a picture of the movement (and dial).

Thanks in advance for your help (and apologies if it is a dumb question ;-) )

Not dumb but the most frequently asked question by beginners, after how to remove stem perhaps. It's a "front loader", search this forum for that.

As JDM says. I have one of those with a later movement and date. The front bezel lifts off - find a sharp knife to get under the join. Then the whole thing comes out of the front.

I've recently serviced two Seiko 66, and none of them were front loaders, but in the first I thought it was because the movement ring was very very tight. I don't know about yours though.

Done! :)

Indeed, introducing a sharp blade at 9 oclock "popped" the glass and ring out and movement came out.

Thanks again for your help, much appreciated!

If you don't know this movement, take care with the click spring and with this washer:

Thank you aac58! Will pay particular attention to these two parts. It is indeed my first attempt at working with this movement!

Just wanted to thank you again aac58 for your warning ! Indeed, that tiny little washer went unnoticed and only separated from the other part in the washing machine :) 

All good now, ready to start the assembling

      Etachron regulation system

      By JohnR725 · Posted

      This conversation is becoming a very confusing. The etachron system is a very nice system for manufacturing watches. As you know it consists of two components the stud and the regulator pins. Beautiful thing of this system is you can open up your regulator pins center the hairspring and as you close the pins they will close equally on both sides providing you centered it in the first place. It's not like you're going to become closer to one side or the other as the definition of the regulator pins is a bit confusing it's not exactly a slot sort of. I'm thinking maybe a little eight reading will be helpful for you. Then the file name was changed by me at the US patent but the wording of Seiko may or may not actually be attached to it soared up? I just did that so I can find it in my files. Normally patents are in people's name if they work for a company the company name will be there you'll notice the person lives in Japan which is interesting as the name would imply that this is a Swiss product. Somewhere I think I have the patents for the stud and I believe that is Swiss like a lot of things their Japanese and Swiss and then the Japanese let the Swiss name stand as it seems you more popular in case as you read up on the patents of the regulator pins or pin will see and it should explain exactly how and why it works also why it's important to always close at an open in specific directions because the pins actually have a shaped to them it's very hard to see the shape as it's very tiny.   As a reminder with this system it's mass-produced. I wouldn't be at all surprised if they use cameras and computers to do all of the adjustments.  The meaning of this is that the majority of watches will function as there supposed to and do what they're supposed to do the system will allow us for some minor in tolerance and has more than likely as I said no human hand is ever touched those watches that's the way they left the factory and they work fine.

      Cap jewel with what looks like a circular engraving around the edge

      These still seem stupid expensive for a bottle, but still £100 cheaper than than the Moebius ones. Anyone have any experience of these: https://www.cousinsuk.com/product/epilame-fixodrop-special-bottle-horotec

      I bought an old Bergeon 5555. The bottom of the tank was full of petrified salts, which also corroded the metal parts a bit. I would use just distilled water.

      INGERSOLL watch necklace - Unsure of make/model

      By EBUZZ · Posted

      Can anyone help me identify this watch/pendant. It was inherited by me from my grandmother and I am unsure as to what it is. It's a watch/necklace with a blue face with the inscription "INGERSOLL" and "Swiss Made". Have tried looking online but to no avail. If anyone knows a make/model or knows where I might be able to find out about it, that would be very helpful.
