Hi all, I've had family issues which have settled slightly enabling me to get back to this.

As per excellent instructions offered by people here, I've purchased some working movements (mostly 2824 chinese clones) but first I got to grips with my Weishi timegrapher.

I aqcuired recently a Seiko 6105 copy (as worn by Captain Willard in Apocalypse Now) and it uses a NH35A movement. As it was recently purchased, I didn't feel the need to service it, but do some regulation

It started out as 2.5 beat error and was presently surprised when I accidentally got the results shown in photo. This watch is sold by Steeldive and I don't try to pass it off as original in any shape or form, just enjoy wearing it.

It's unusually comfortable to wear, I think because the case is chamfered to a rounded form on the edges. I really didn't expect to get the BE down to 0.1.

Maybe it'll stray, but not bad for a start!

My son is about to go to California on a post-doc appointment in UC Davis near Sacramento and I'd been promising him to regulate his watch pictured with its 7S36 movement.

Whilst I didn't get the results on my Steeldive, I did manage to get the BE down to about 0.4 which will be good enough for him.

This was his first mechanical watch, so hoping he moves on in the same vein if he ever comes back to UK.

      Hour hand won’t go past certain spot when adjusting time forwards

      If the watch is new, just return it to the seller for a refund or replacement.

      Keevo, Welcome to the group ! I'm thinking that you have some damage to the hour, and/ or minute wheel. Possibly just a bent, otherwise damaged, or missing tooth.   Your photo didn't post that I can see. I think you'll have to open it to start really finding the issue. Best, Randy

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

      By mikepilk · Posted

      In cap jewels on several watches I have serviced over the years. I've recently serviced a couple of Longines movements where the cap jewels were colourless. They are a real pain. Without colour they disappear when immersed in any liquid for cleaning 😲 Not necessarily. Cousins do a 10ml bottle for £26 which will last me for years. That's just half the price of a simple Bergeon silicone cushion, so not too expensive 🤣

      Etachron regulation system

      By BobG · Posted

      I wanted to post an update as I have two movements running really well now, 230-250 amplitude , 0.5 and under beat error, and +/-8 seconds or so. I removed the hairspring assembly in order to start over and noticed that the terminal curve between the stud and regulator arm was distorted. The stud was lower than it should be. I massaged the curve to look pretty good and reinstalled it. I followed Alex's video advice, best I could with 10x magnification, and with the regulator arm set in the middle of the curve I adjusted the stud so the spring was centered. I then made sure I could move the regulator arm the entire terminal curve without upsetting the coils. I then put it back on the Timegrapher and began closing down the regulator pins until I saw a change in amplitude which means to me that the pins were now pinching the spring. I opened them slightly and it looks good except I have a 0 on dial down, +3 on dial up but -16 on crown down.  I'm a bit stuck on how to adjust out the positional error. I also noticed a drop in amplitude, 180-200 on crown down. In the other video link I posted at about minute 26 if I remember he adjusts out positional error by manipulating  the regulator pin gap. With crown down the hairspring falls away from the pin and the rate slows so he closes the pins a bit to keep them tighter in crown down position. That means the spring is tighter on dial up as well but then he moved the regulator arm to slow the movement.  There must be some Seiko experts here that have some methods for dialing out positional errors.
