Newby and first post. Before I go any further with this acquisition, can anyone confirm whether the case back on my Deep Sea is friction fitted or screw down? If a screw down, where might I find the unique case wrench required

Thanks,

Patrick

welcome to the forum an Introduction is usual.   In answer to your question the Jaxa  case removal tool has attachments  which will fit this watch back.  There are cheaper versions of this tool on ebay.

 Sorry forgot to mention  They are usually screw down,  A sticky ball will also remove them if they are not too tight again available on ebay.

Thanks for the quick reply. You say they are "usually" a screw down. So is that to say this model has been made with both friction fit and screw down case backs? Sticky ball won't budge it if it is indeed a screw down and my LG case wrench doesn't come with this type of attachment.

when a screw back has "flats"   there was a box wrench to un screw it.   grind a cresent flat at the tips will do it.    vin

Thanks Watchweasol and Vin. As it turns out, I found the original box my LG case back opener came in and found polygon cover pines and voila, the case back opened. In all my years collecting, haven't come across a polygon that needed opening.

Hi Just be aware of the fact that I have seen watches with snap on backs with that design but the  Flats    are not as well defined as the one you have so on that basis I would say its a screw on. Some backs can be well tight and take quite a bit of force.

a sticky ball or a big piece of ducttape can do the trick, or the jaxa WW mentioned.

It has several insert fitting most normal casebacks.62975484_ScreenShot2020-04-18at15_16_07.png.4b7bfd1b3c11fdff79d41cf9f340c0fa.png

      Lathe motor advice

      By JseTay · Posted

      I sure appreciate your comment! I will look into one of those or maybe something similar. I of course will check your video to have a better idea.  by the way, that’s a beautiful lathe! Mine is a little peersless, but I just bought a Boley & Leinen that is on its way. That’s the one I am looking a motor for. It comes with a motor, but I want to replace it for  one that has a speed controller.

      Indeed. I would not attempt one. Here is my messy Sherline setup

      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.

      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
