0S60 Miyota

My engagement watch was a Briel, which turns out to have a 0S60 Miyota movement.

I paid goldsmiths to replace the battery, boy what a mistake. When I collected it the crown came off in my hand. Goldsmith said they can't repair!!! They paid me £250.

So this is when I did some research and took the back off the watch. I believe the stem is still in the watch. But I think I can repair by replacing the stem and crown. I still have the crown.

Could some one advise what stem I need and how can I attach the crown, doesn't appear to have a thread but I think it should have. I can get more photos if needed.

Many thanks

Strange. Can you provide a picture of the crown. It would be helpful to know if the stem simply came un screwed or snapped off leaving some of the stem left in the crown. 

I realise you had a bad experience with one business but I wouldn't completely disregard seeking out the help of another, at least if there's any watch specialists around your area, The watch mainetence/repair work of jewellers, particularly large chain jewellers (like goldsmith's) often leaves a lot to be desired and what's 'impossible' for them is childs-play for someone who is a watch repairman first and foremost.

From the first photo I can see part of the stem, I would say its broken off. The button screws on.

Stem from here. https://www.ebay.co.uk/i/253007986837?chn=ps&dispItem=1&adgroupid=13585920426&rlsatarget=aud-133395220866%3Apla-142405555266&abcId=&adtype=pla&merchantid=9391734&poi=&googleloc=9041119&device=c&campaignid=207297426&crdt=0

Excersise extreme delicacy when pressing the stem release. It is very common for people without the proper experience to basically damage that mechanism. You'll need to press on it while gently pulling the remaining piece of stem from inside the case with a pair of tweezers. And the stem may need to be pushed, clicked in to the proper position (fully in) otherwise the stem release leaver wont be there where you're pressing.

My thanks to both Oldhippy and Ishima. All responses are excellent.

I think old hippy is correct in that the crown was stressed at some point and does appear to have snapped of. I intend to get some better photos later as per Ishima.

I also take your points Ishima. My experience with Goldsmiths was very emotional as to have a very important watch (emotionally not in terms of £'s value) returned broken was a true shock , the lady on the counter at my local store was near tears and I hadn't said anything. My true concern with Goldsmiths is that if I can research that stem replacement is relatively simple, Goldsmiths should have been able to replace, but I suspect as with most large scale businesses of this type they went for the easy option and gave me money to which I now have a very nice Hamilton Crosswind and the potential to repair my original watch.

Also, looking at the watch removing the remained stem may be a step too far for me as it may not come out easily as there is little if any to grip so I may have to find a repair support locally (not that many around here Tamworth, England) that according to google. I have sourced a stem on ebay for £5 from USA so, if will see where I go.

But again to both Oldhippy and Ishima my thanks for your time. I will post photos later.

 

thanks

Hi all,

Just been emailed the stems info below:-

065.453 - 1800 Length
065.533 - 2400 Length
065.557 - 2400 Length
 
How do I measure length of stem required?

You will need to cut the stem to the right length when you fit it. For this it is better to fit - measure - adjust until it is right rather than to cut to a "spec" length and fit blind. See here for an excellent walk through by Geo.

As for the crown, if it is stainless steel or plated brass your best bet is to use alum to disolve out the remaining stem leaving you with clean threads to fit it to the new stem.

great responses, my thanks. Looks like I have a little work to do.

Here's some more images. Notice in the crown it looks like it snapped off leaving the stem head in the crown, but I could be well wrong.

The stem end is like any other stem.

That bit I think is part of the crown.

PS - Sorry about the DNA under the crown [emoji33]

 

PPS - Got the stem from Leosics in the UK.

Does not look good, Check if you can find a suitable replacement on Cousins UK or other source.

If you can't get a new crown you can drill and retap the original one. You'll need to find a watch maker or model engineer with a lathe to drill the centre of the crown. The stem will be a Tap 9 which is a 1.1mm thread. You'll need a bottom tap as well as the usual taper tap to cut the thread.
Not difficult in engineering terms but booldy annoying after a trip to a usually reputable retailer.

You will not get a crown other than the original. It is custom made for this case only.

A generic in a different, but acceptable style is possible, no?

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.

      Main spring

      By Jon · Posted

      I would go for the dearer spring. You won't need to remove the spring from the carrier ring and then use a mainspring winder to get it into the barrel, for a start. Also that spring is closer to the needed dimensions, especially the length. The length plays a part in the mainsprings strength. If you double the length you will half the force (strength) of the spring and vice-versa. A spring with 20 mm less length would be about 7% shorter, so technically would be 7% more strength, but I find halving this number is closer to real-world findings, so the spring would be about 3 to 4% more strength/force. On a mainspring that ideally kicks out 300 degrees of amplitude, a 3% increase in amplitude would be 309 degrees. Increasing or decreasing the length of the mainspring will affect the power reserve to a greater or lesser degree. It depends how much shorter or longer it is.

      What tools does ebay have to offer this week.

      By Malocchio · Posted

      I recently bought this but not on ebay. I figured if I want something Japanese I better check Japanese auction sites since these don't seem to pop up on ebay. I paid 83 € plus shipping & taxes. I think it was pretty reasonable for a complete set in good condition.

      Did you take the friction pinion off the large driving wheel and grease it? Although, now that I think about it, that shouldn't have any effect on the free running of the train if the friction pinion isn't interacting withe minute wheel/setting wheel...

      I did in fact use Rodico to get the spring into general position and "hold" it there while I used a fine oiler to make subtle positional adjustments.
