Today, being a nice sunny day, I decided it was time to give these two watches a quick check and internal clean of the crystal.

Sector 155

15 years old

Once I had cleaned it and the movement was back in, I noticed the chrono was acting up. Looks like the rubber used to cover the buttons has had enough.

Anyone know where to get replacements from?

Breil Ducati One

14 years old

This one is a pain. I have had the movement out once before with no issues.

This time the stem does not want to go back in. With or without the stem release button being depressed gently.

What could be the issue here?

Hi Ro63rto, it looks like a regular O-ring from here, can it be sourced as such? The second one may need a little grease on the stem if the keyless works is still holding together as it should...

Hi Bob. Sorry for delay in reply. Tapatalk not giving notifications [emoji35]

The Sector one needs a whole new black button/cover for the chrono pushers. Can only see them listed on one Italian site who only sell to the trade.

The Breil I did grease the stem/gasket before reassembly. It almost feels like its pushing on something down there. It went together fine a few weeks back.

Found Creative Watch online. Looks like they sell to the public so sent them an email.

As for the Breil, it uses a Miyota OS20.

Found a seller on the bay selling new ones for £12 so may opt for that if I can't find the cause.

Does it look like the pinion at the and has been broken off? If not the long large diameter might be designed to give stability of the stem in the case.

Just a thought! :)

Hi Ro63rto,

 

I think the end is broken when checking with my OS10 movement which is a version of the OS20 (same stem) but I may be wrong.

 

The Miyota OS20 is readily available and so is the stem from Borel. Although the movement, stem included, is about US$30, the stem alone can be had for about US$5...maybe it is a good idea -- if no picture is available on google images -- to order a new stem and compare. Worst case scenario you'll only be short 5 bucks but have a spare stem...Just a thought!

 

Cheers,

 

Bob

I cant remember correctly but I seem to remember it was longer.

Might explain why it refuses to go back in place.

Thanks.

The only os20 stem pic I found was very blurred so cant tell.

My brother wont let me open the one I gave him for Christmas to compare. Says I'll break that one too [emoji24]

If the pinion end is stuck inside I'll have to get it out before inserting a new one.

Looks like a bit of disassembly required.

If all else fails, theres an os20 on the bay for £11 at the moment. Might just get as a spare just in case [emoji6]

Just ordered replacement stem #065-453.

I'll test fit before stripping the movement.

No idea where the missing pinion bit has gone though. Hopefully not stuck inside.

Anyone in the UK have an account with Boley in Germany that would be willing to help me out? [emoji4]

They stock/list the black push button covers I need for my Sector 155 Chrono but refuse to answer any of my emails.

    • Thanks for this post MikePilk, I just came across a similar problem with an Omega 1022.  The problem I had was the seconds pinion spring was bent out of shape and did not even engage with the wheel properly, so the seconds hand was not moving at all. (no power loss though :) I removed the automatic module so I could access the spring and work on it. Once I bent it back close to the right shape, I experienced the same problem you reported about power loss.  Many tweaks later, and the seconds hand is moving properly again, with amplitude back to good numbers again. Cheers
    • After cleaning up the pivots, I made bushes on the lathe. At this point I've pressed in 6 bushes (3 sets) and the wheels turn smooth. What I can also tell you, is that I'm not looking forward to final assembly. Getting the pivots aligned seems to get exponentially more difficult with each wheel that is added.
    • Islands are interesting places to live depending upon their size and other factors. This is a bigger island and it has a bridge to get there at least on one end. It's also big enough that you don't have to go someplace else to get things typically. It can be a problem if you get a job in Seattle though. Yes I've known of people who commuted from the island to Seattle for a job and I don't quite remember how many hours it took but it took a long time. So basically islands are nice if you don't have to leave very often.
    • Thanks @JohnR725! Everything you say makes a lot of sense and is encouraging to read.
    • isn't it nice to have a decent case open or when the case doesn't want to be opened? In the case of a Rolex watch that supposed to pass specific water resistant testing you probably do need to tighten the back down. But they shouldn't be tightened so much that they risk stripping the threads out. Then the other problem that comes up is the gaskets can start to disintegrate and then getting the back off can be quite a challenge unless you have a really good tool and perhaps some penetrating oil to loosen things up. Yes really nice case marking. When I was in school we were taught to mark the cases and  the American watch and clockmakers Institute even had a? So if you joined at one time they would give you an identification number. They were explaining or giving an example of if the watches ever found in you have a unique number they can perhaps figure out the history of the watch or identify the body it's attached to for instance not that that probably comes up that often. So you got a unique number and even made a special metal stamp that you can purchase. It wasn't a super big aggressive stamp but still it left a mark in the back of the case. Then I heard from people at work on Rolex watches they were using a felt pen indelible but later on they decided that was bad because apparently the ink could release  chemicals although it seems like once it's dry that shouldn't be an issue. Then of course today was nice is you can keep computer records sealed have to mark anything at all I personally find it's best to leave no reference behind that you were even there. Especially when you have a beautiful watch that has no markings at all and now it has your scribbling all over it not good typically if there is a typical and watch repair?  a lot of minor repairs you don't need to do a complete servicing. But beyond a certain point you're going to have to take apart a lot of stuff you're going to disrupt the lubrication even if it looks perfect right now and yes you might as well just go ahead the service the whole thing. also in a watch like this where a lot of things seem to be going on the complete service would be better then you'll know exactly where you stand versus dealing with unknown mysteries for prior repair.
