Hi I'm very new to watch repairs and was wondering if anyone could tell me if there is an alternative to a miyota Quartz movement 6M12 with the date at 3h looked on cousins and it is now obsolete.

Looked in my drawer and had some different Miyota movements . The only difference is the thickness of the movement as i see . The 1M12 is thinner then the 6M12 . Took a picture of them . 1M12 from left and 6M12 in the middle .And the  6M17 has a taller hour and minut wheels . post-644-0-04818600-1427737866_thumb.jpg

Hi MarkRiley and hi for everybody.

 

Welcome to the forum. You can buy a new one at ebay nº 251899461433 for 6 GBP. There is 5 available and the seller is in UK so postage will not a big deal as for me (Portugal).

You probably won't need a new crown but to re-use the old one as long as it is the same tap size...and all goes well recovering it.

Hi Mark,

 

Just a note on using the old crown.  If it's a plated crown, be sure that no part of it is worn down to the base metal, as moisture can be absorbed through some base metal castings, leading to corrosion of the stem (I've seen this many times).  Always best to replace the crown when replacing a movement if the part is still available ... they aren't too expensive, and it's added piece of mind.

Good advise Lawson.

 

By the way, where have you been?

 

Cheers,

      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.
