Hi.

I have an oris big day/date which I bought brand new last 2019. I rarely use it except for occasionally winding it from time to time. In short, I kept it in my watch case most of its life with very infrequent wrist time.

 

Anyway, I used it this week and I noticed that it stopped after 2 days of wearing it more than 12 hours per day. I tried to shake a little bit to make it start but stops after a few seconds. When I tried shaking it for 1 minute, I noticed a clanking sound inside which I never heard since new. When I opened the back since It's out of warranty I noticed the rotor was loose and when I tried to screw it in I can't lock it.

Can I do this on my own or bring it to oris?

Any suggestions appreciated.

I must admit, this has got me beat. I have no likely explanation why these two screws will not release on a movement which is only 5 years old, in decent condition, with no signs of rust. Sorry to ask

Yes it is. Yes looking closer again it does just look like a metal fracture. Maybe you'd be better having someone look at it for you.

I'm sure i read somewhere that they did make for Oris at one time. Oris were always originally in-house makers then sold out  some time ago and as far as I know are fairly recently back to in-house bu

Trying to work out how it was fixed in the first place.

It almost looks like it was glued in place?

Edit

Is the screw still in place on the weight?

It looks like the boss has broken off the automatic bridge.

Hi.

Thanks for the reply. Yes. The screw is still in place with the weight/bearing.

My watch was never opened since I bought it new from the watch shop with 3 years warranty until 2022.

Do I have to change the whole thing or just glue it back?

The raised part in blue ( boss?) is missing. Maybe it ia still attached to the screw. Can I try to remove it and just glue it back with superglue?

It still works when wound and runs +2spd

I expected that's what's already been done once before looking at the residue on your photos.

Depending where you are and what experience you've got it's a simple fix to replace with a new bridge.

Wow!!! That means it was not brand new when I bought it.  tsktsktsk.

Lesson learned.

 

Is the sw200-1 bridge interchangeable with the sw220-1 ?

My experience is limited to mostly seiko watches strap change, bezel change, regulating speed via timegrapher and hammer changing, change watch hands and face, change crown and stem.

Will this be enough for me to pursue this on my own?

Maybe the resolution on my phone is not high enough, but I don't see any glue residues. It looks more like metal fatigue or defective brass.

Was the watch dropped, received any hard bang or abused in any way? If not, Oris should replace this as it is defective manufacturing.

The watch was never dropped/bumped.  I only very occasionally wear it and stays inside my watch case most of the time. 

I also follow instructions on the amount of winding needed to start it.

Very rarely used and pristine outside condition including the metal bracelet.

Looks like the bearing has sheared off at the shoulder 😥, thats a real shitter for the OP. Bit of a weak design there, a black mark for Sellita unfortunately, why not a full thickness bush ?

It depends if this is Sellita or do Oris have them made elsewhere as it's only based on the SW220-1?

I'm sure i read somewhere that they did make for Oris at one time. Oris were always originally in-house makers then sold out  some time ago and as far as I know are fairly recently back to in-house but maybe not with everything they make. 

Besides that Oris have for some time now RED trademark auto rotors.

Yes just had a look the 752 is based on SW220-1 which is an ETA 2836 clone. I'm sure this is the Sellita caliber that got a pretty bad rap with quite a few design flaws . In an interview with one of the main men , he admitted that they had made some mistakes .

It appears all the Aquis models have movements based on a Sellita engine. Interesting that they describe it as a based on movement 🤔 come on Oris !! ...lets be more honest and accurate about what you tell folk shall we...It's a Sellita movement that you've modded 🤷‍♂️ .

Will do that after the holidays. I also follow a watch thread here in the Philippines which names the best  technicians for swiss watches other than the authorized watch repair shop. 

I just thought that I can just easily replace it on my own to get my hands wet on sellita movements.

Thanks everyone for the good advice.

It depends what screwdrivers and other tools you've got to have a go yourself.

Page 14 shows what's required to swap everything over along with lubrication points.

Thanks.

Is there a difference between moebius 9010A and 9010B besides the color?

The B does just indicate that it's blue.

Are there any jewels I need to remove and replace from the bridge? 

If that will be the case, I'll definitely send it to someone experienced.

The bridge if bought new from a supplier should come with jewels.

Hi.

I just convinced myself that I'll try to do this. I just have a couple more questions.

1. Can I just tap out the rotor bearing with the screw on since it came off with the weight and can't be removed?

2. Are the rotor bearings of sw200 and the sw220-1 compatible?

3. Is the bearing friction fit?

      Hi guys. @VWatchie Those images are self hosted (not hosted on this server). Do a look at the page source and you will see this. I’m afraid, I can’t have control or backup images not hosted on this server. ( They seem to be served from here: https://qehvsw.bn.files.1drv.com/) This server is backed up fully every night and the database is backed up and versioned every hour, all stored off site on Amazon S1 platform. It’s hard for us to lose data. Ive got a huge overhead of space on this particular server the site is served from so no worries there 🙂 Sorry all for lack of response so far, I have been extremely busy and am embarrassed to say that priorities had to be set in place for a while.  Be assured that i’ve got constant monitoring and alerts should the site be in an extended problematic state (down etc) and work on these issues if they arise.

      Web sites are cheap. Message board are easy. Hosting both is less than 100 usd a year and small advertising would cover most of that.  In the discord group we did some 15 min poc and threw up a couple of different message boards on a domain i host.   The real value is the data / information / hive mind While I'm a rank amateur in watch repair the information and assistance on this board is invaluable. The members on here are friendly, entertaining and a wealth of knowledge This is what needs to be preserved  --Jeff

      HWGIKE#57 Valex FEF 190 15 jewels Swiss lever full service and repair This one was waiting for a balance staff replacement in my cabinet parts and case cleaned up with a new balance staff and a 4th wheel as the original 4th wheel had a broken pivot for the off center second hand. I never attempted a balance staff replacement before however I received a Bergeon Molfres (i was hunting it for about 2 years) and with the help of it I managed to remove the old staff and riveted the new one in. It also received a new MS, crystal and the hole for the MS arbor was also tightened. With the new MS now it has an acceptable performance meaning that the amplitude goes up to 280 fully wound, has an acceptable beat error and I have the two nice lines but only dial up, dial down is not as nice and I could not figure out as why. I have the two lines but the amplitude is dropping to around 230 and the lines are a bit hairy. Both dial up and dial down the lines just go up and down without seemingly any pattern. I cleaned the movement two times, and then a 3rd time pegged out the main plate and train bridge holes but made no change. Both the HS collet and the roller table was too lose on the new staff... I did not count how many times I took the balance cock off to sort out the HS collet, the roller table and the beat error, somebody before me also shortened the HS by pushing it out a bit and it seems every time somebody is messing with the end of the HS the protruding bit is most of the time twisted bent etc. This one was probably one of the most challenging repair and service. I might take the new MS out and clean it lubricate it as I just pushed the new one in to the barrel from the retaining ring. Plus started to re-read the theory of the escapement and how to analyse the graph on the timing machine: Greiner Chronografic Record manual. I am also thinking to put the watch on a 24 hour long run with the eTimer SW it once helped me to figure out what was wrong with a watch. There is an interesting part of the Greiner record manual talking about the pallets and the end shake of the balance and pallet staff. Maybe this is my issue? Who could that possibly identify? After a few years now I am still without a clue how could watchmakers make parts I can only see with my microscope or how could/can they carry out complicated services impossible to do.. real magic..... .... ..... before I sent this post while the pics were uploading I had an idea, i was browsing the possible outcomes on the timing machine I had one for magnetism..... so I demagnetized the movement and it is not hairy now.... two really nice lines 0.2 ms beat error still a bit wavy, but a lot lot better..... argh....
