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?

      Is this pallet fork over-locking?

      By Malocchio · Posted

      The entry jewel's not as bad but seems still too much lock. I do epilame the escape wheel and pallet jewels, then run dry for about 15 minutes, then put 9415 in exit jewel very little at a time and check with backlight how the oil's distributed.  Another question is about capped escape wheels. Should I somehow wear the epilame off the pivots before installing the wheel? I normally let the escape wheel run dry for that said 15 minutes when there's no cap jewel.

      Bezels - What am I doing wrong?

      By Malocchio · Posted

      Sometimes there's a certain place under the bezel where the case knife is supposed to be placed. In this borrowed pic there's a small crack at 3 o'clock.

      Bezels - What am I doing wrong?

      By Waggy · Posted

      Hi my fellow forum addicts, I'm writing this as I seem to have a hole in my knowledge (probably one of many!) I seem to have a horrible time removing bezels from watches. I am talking about the rotating type on sports/diving watches. I see many videos where the guy on screen barely inserts the case knife under the bezel and with no effort it pops off easily, then at the end it clicks back into place by hand with no effort. I am sure that part of this is due to skillful video editing, but I seem to wrestle with them, I have tried case knives and  even when using the tool below, I tighten it up in several positions and nothing happens. On a many occasions I have even warped the bezel in my attempts to remove it. Similarly, I have issues replacing bezels after cleaning etc. and often they have to be replaced using a press tool and inevitably are far too tight and will not rotate or loose to the point where they fall off or loose their click (perhaps due to micro warping when I tried to remove??). It is now to the point where I am actually avoiding watches with bezels as my success rate with them is terrible......please help!! In short I am asking: What am I doing wrong? What is the best method for removing bezels - how do you do it? What is the best method for replacing bezels - how do you do it? Any tips or tricks? Thanks

      Amplitude still seems low, but I'm going to let it run in a bit and revisit. Meanwhile, got the first layer of the calendar works together and made sure the date ring snaps to both in quickset and regular setting. The mechanism is pretty cool, so I took a video.

      This is the part that need replaced if anyone can point me in the right direction.
