Help Fixing Omega Chronostop - Broken Pusher Tube


Recommended Posts

I thought the pusherkey was a little expensive so i did my own . From a 5 mm stainless steel screw screwed in a wooden handle . Had a friend laserweld an old pushercap to it . The tools have become cheaper since then . Can't u use the old pushercap to screw the new pusher in ?  if you still got it ?  Otherwise i think it's the red handle that fits the omega pushers 3,65 mm .That is what my pusher is  https://www.cousinsuk.com/product/chronograph-pusher-tube-fitting-removing

thanks great idea with the old pusher cap. think i'll try that!!

Well worth a try, but be very careful. I tried to unscrew a tube using the old pusher held in a pin vice, it was so tight that it did nasty things to the spline. :( At least screwing it in you can stop soon as it gets reasonably tight.

I have an ongoing issue with a Breitling pusher.  On another forum was told by a member who worked for 6 years with Breitling that all pushers & crowns are secured with loctite (green) which he thinks is loctite 290. To shift, heat is required but on a crown or pusher it's difficult to achieve without damaging the o rings. I might have found a replacement part from the USA so will not attempt until I see if I have.

Thanks Bob but no. The problem is the pusher screw is bent and has to be to be removed to straighten & remove o rings. Unfortunately Breitling do not supply parts and so it's a real issue here. The Avenger is also made if Titanium so parts are as rare as dragoons teeth. Found screw in the USA but not sure if it fits. Found a pusher cap @ $240  :thumbsd:

No the screw is not titanium. It's one of those jobs that can easerly go wrong. It is not a conventional design either the end of the pusher is loose but magnetic. It,s to improve water resistance. Go to tis web site which explains better than I can.

Ok been working on this problem this morning. Apologies first, the pusher has NOT got the detachable magnet as I first thought but the end of the pusher is however detached. The magnetic pusher style is only for their quartz movements.

 

However the part that I received from  the USA was not correct so I had to straighten the existing parts. See pics attached but basically after stripping the pusher I could see using a loupe that the bend was where the pusher screws into the cap. Despite adding heat the shaft of the pusher still would not move, or to be precise I was not sure if it was moving or braking. So I decided the best option was to straighten it still attached to the pusher cap. I clamped the pusher cap in a a hand held vice and slowly & very gently straightened using a punch that only just fitted over the shaft. Then re-assembled silicone greased the tube & o rings re-fitted & job done. Just need to service the watch now !!!!

Good job CB, I do that all the time, you just got high tech for me on this one...I use pliers and eye ball it, trial and error so to speak...so far so good for me...cross your fingers! Your "walkthrough" will be very helpful for me next time I tackle one!

 

Cheers,

 

Bob

 

PS. I've only worked on those in cheapo, non interesting watches for learning though.

Hi i just thought i'd post back with an update. I finally got a few spare hours to continue trying to repair my omega. I slowly finished reaming the hole out until i could just see the threads. i compared the thread on the omega tap i got from cousins to a new pusher and they seamed the same thread to me (only comparing by sight) so i thought i'd risk it and give it a go. I managed to very slowly clean out the threads using the tap. and have managed to get the new pusher to thread in. Hurray!! (i guess they were the same thread then)

 

Its a tiny bit from threading in all the way so may have to play around with it a bit more before i put the watch back together, but I'm really happy with the progress so far. So thank you to everyone for the advise and support.

 

I'm finishing for tonight so will post back with another update soon.

 

Just out of interest would anyone recomend using some kind of loctite to fix the new pusher tube in or just tighten it to hand tightness? if so what kind would you recomend.

 

Thanks again

    • At a friend's request, I've obtained a key for her long case clock which has been silent for some years. On winding it, the weight only rises a foot or so from the floor - & is not visible above the lower panelled section - before the key meets significant resistance. However it then runs quite happily for a day or so by which time the weight is again on the floor. I haven't had the chance to examine the movement but would be grateful for suggestions as to what might be happening here.
    • Despite having to change up your magnification and get your head into the super micro mech zone, I admit I'm not adverse to buying women's watches. You can finish up working on some good high end movements for a fraction of the price of men's. They also finish off that little black dress number and heels look on Saturday night outs. I would laugh but i have had some very odd Saturday nights out , ok go on then I'll laugh, i just made that up....ahem...😅
    • These are some from a couple of job lot ebay batches totalling 40+ watches I got a few weeks ago, ~£2 or less each. I'd only looked at a couple of specifically interested ones so far, as I already had others of interest to look at I've just gone through some of the smallest ladies ones. I was expecting them to be mostly cheap quartz, but only one of them was - the others are all look like good quality mechanical ones! There are also a good selection of other types, including a couple of nice looking old Casios - and some blingy things..          
    • Its a nice classy watch Rich, the only problem i have with it.......if you know me well enough then you know what that is. I've already forgiven you for it though 🙂. 
    • My Omega Seamaster aqua terra.  It's just me, very understated but classy ( not that I'm classy). I don't like dive watches, the bezel puts me off or any kind of bling. I prefer indices to numbers. I don't have any other luxuries, not into clothes, seldom go for expensive meals etc. So it's my little treat to myself.  Not my watch but exactly the same, just got home and taken it off.
