Oris Aquis Big day date rotor/hammer fell off.

[boogeez]

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.

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?

[boogeez]

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?

add more details

[boogeez]

Forgot to add. 

Will I be able to buy an aftermarket stamped bridge? 

Saw some bridges with no stamping for sw220-1.

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.

Yes looking closer again it does just look like a metal fracture.

Maybe you'd be better having someone look at it for you.

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. Will take a look over and see if I can do this or pass it on to experienced watch techs.

What do those red/white arrows mean?  (Lubrication points?).

rephrase

[RichardHarris123]

Where to lubricate, how much to add and what lubricant. 

[GPrideaux]

There's a key on page 9 of the PDF that you can use to interpret them.

[boogeez]

thank you very much

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

 

[boogeez]

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 B does just indicate that it's blue.

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?
