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?

You should just be able to get enough purchase on the broken part of the bridge with maybe an old pair of tweezers to remove the screw.

Thanks.

Will try that out 1st. I was asking the questions just in case I can't remove it.

...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 .

Oris is on my s*** list.  My wife bought me an Aquis 400 last year for my birthday.  It's a beautiful watch on the outside, not so much on the inside.  It features a dual-barrel design and 120 PR.  One morning I noticed it wasn't running after wearing it the day before.  After some research and contact with the AD it appeared that losing PR even while wearing it was not uncommon.  So I was advised by the Oris service center to wind it 210 turns, wear it every day and report back.  I think it took 10 days for it to stop so it was not even keeping up with PR while wearing it 18 hours a day.

I discovered that the rotor only winds in one direction whch I though was odd.  I also found out that Oris had updated it with a -2 movement and also read about a -3.  It took four months at the service center in Boston to procure one from Switzerland and get it back to me, with a -2 movement.

So I don't know if Oris or Sellita is responsible for this clunker but my watch is up for sale.  I have better things to spend my money on...

Shame that, Oris used to have a good reputation 60 years ago.

Doesn't Oris source Asian made movements?    Lower quality !?

I tried what you said and you were right. I was able to remove the broken part. Thanks again.

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.

Hi.

Just making sure that this is the correct part before ordering. They don't have the stainless steel one. Is the gold / brass good enough?

Thanks in advance.

Where are you buying? Where are you located? Can't order from CousinsUK? They have it.

The brass colour one will fit as well, but it'll look quite ugly.

Yes the brass will work but as per @Knebo comment I too think it would look wrong and potentially destroy any value in the watch.

Hi. I'm from the Philippines. I'll see if I can order from cousinsuk.

Thanks for the advice.

Thanks for the comment.

Honestly, I haven't sold any of my automatic watches since I started my hobby/fondness for automatic watches. But I agree with " it will look ugly".

Yes those are the lubrication points.

I have these manual oilers. Which one should I use? ( sizes are in mm .. 0.2, 0.3, 0.5, 0.6 )

Or a better question is How to know if it is enough?

That's the $64,000 question when it comes to oiling.

Have you got both the oils that you'll need?

I use the black smallest oiler for everything apart from grease on the keyless works where I use the biggest.

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.

I'm just reading your post here again. Replacing the automatic bridge isn't hard, but as indicated above you'd need to oil the jewels. Do you have lubricants, specifically Moebius HP1300 or D5?

You should also have decent screwdrivers. If you don't plan on cleaning the parts of the automatic module, make sure you're extremely careful not to contaminate anything with bare fingers, dust, etc. If you do want/can clean parts properly, DON'T wash the reversing wheels (unless you also have Lubeta V105...).

I was able to source 9010 and d5. They are available in either 2ml or 0.5ml bottles.

I either use gloves or finger cots when handling the watch/watch movement.

I also have the screwdrivers I need since I like tinkering with small parts in electronics. It's relaxing for me

Can I just use rodico for cleaning dust off?

I was able to source 9010 and d5. It is available in 2ml and 0.5ml decants.

I also bought a generic sw200 automatic module to practice on before I actually replace the one in my watch.

As they say, practice makes perfect.

That's great! 0.5ml will last you years.

I forgot to ask. Since this is my possible 1st purchase from cousinsuk, is the part an original swiss made automatic bridge?

Yes, these are original parts by Selitta

Thanks. I already ordered the part from cousinsuk. I'm just waiting also for the complete chinese automatic bridge to practice on. 

[boogeez]

Finally, bought the part from cousinsuk. Nice swiss made.

I think its Asian made, slightly lower quality compared to Swiss.

The movements may be made in Switzerland but I expect this is correct and the parts are made in China.
