Help removing broken pusher tubes Omega 176.005


Recommended Posts

Hello all. I inherited a Omega 176.005 with a badly dented and pitted case. I got a hold of a replacement case that is in better cosmetic condition as well as a new set of pushers.

The problem is I can't remove the old pushers from the case as they have been broken off and the splines are completely gone. I bought a screw in pusher fitting & removing tool but without any splines there is no way for it to grab and unscrew them.

Plies were too big to grab them and I couldn't get enough leverage with tweezers. See the pictures below. Any ideas on how to get these off? Any help is appreciated.

You first have to determine whether the tubes are screw-in or friction fitted types. Look inside the case to see if there are any signs that the hole is threaded.

If the tube is a screw-in type, wedging in a slightly tapered rod and turning it might work. WD40 and heat will help loosen it. Worse case scenario, you might have to carefully drill/ream/file until the remnant of the tube disintegrates. If the threads end up getting damaged, then you would have to thread the hole for the next bigger size pusher tube.

If the tube is a friction fitted type, there are specialized tools to push it out.

But spending money for an expensive tool for a one-time job doesn't make sense. Consider sending the watch to a competent watchmaker.

Try heating the case to break any threadlocker, followed by soaking in Coca-Cola for 24 hrs. You can buy micro screw extractors or shape an old screwdriver into a  wedge shape.

Thanks for the replies. The tubes are definitely the screw-in type. Any recommendation on the best way to apply the heat? Should I stick the whole thing in the oven or do I want to apply it locally at the tubes? Thanks.

I usually use a butane microtorch for heating seized screws.

Depending on the type of threadlocker used, sometimes the parts need to be heated to 150°C before the bond is weakened. 

Before applying heat, make sure that any heat sensitive parts are removed, like orings, gaskets, etc.

Although it might have a right hand thread, it usually helps to turn the part in both directions to break the adhesive bonds.

invest in some cutting broaches, they have a slight taper and the 5 sides are sharp and will dig into the side of the pusher, remove in a counter clockwise direction in case the pusher is threaded, if not threaded it does not matter which direction, I use a heat gun to heat stubborn pieces that are locktited in, if still will not come out the broach can cut the majority out so a threaded tap can be used to clean and straighten the original threads in the case head, one could make an easy 4-sided tapered broach from a proper sized length of steel.....

    • The guy will have set in a maximum bid that kicks in a new figure everytime someone places a single higher bid or their maximum steps up. A sneaky way to win is to snipe bid in the last few seconds but i think even that was pointless against sniping softwear previously. Recently I've noticed something new, the outcome is sometimes delayed while ebay determines the winner, so regardless of what bid is placed at the dead point of auction end the highest maximum overall bid takes the item. The highest maxiumum bid that is set during the aution's open time. Though frowned upon , what i like about sniping is the fact it can avoid getting into a maximum bidding war with others that watch the last hour. They up their maximum bid then you up your maximum bid and so on. Placing your max in the last few seconds prevents all that drama 😆, you either win or you dont. I like to close my phone case and not look at the final result for an hour or so 🤣
    • I must say I'm the same, buying a complete set of something saves a lot of time and effort but there is a certain type of gratification for me hunting out all the add-ons.  Ps hands down having a psychotherapist for a wife is way better than having a psychopath for a wife in my experience 🙄  
    • Mark, good info.   My attempted photo through 10x loupe.  Not the best but an effort.  As much as this sounds dumb, the HS has increased its gap from the the cock.  And, seems to spin 3 times longer.  I think I have some residual fiber from my pegging.  What is small enough to clean out these pivots? Or is this where the L&R correct cleaning product helps?  Liquid movement will ensure the pivot holes are clear?  Yup, I have 3x cheaters and the 10x Loupe.  I will have another run at examination.  Everflex green sticks.  Quick google, will have to dig deeper.  Perhaps that is the key to clean pivot holes.   Noted on mixing Naptha based solvent and IPA, water based.  I have a gallon of Coleman White Fuel for about 15 years.  Time to use it and use as rinse.  I stumbled on a L&R Master for $20 with all original L&R jars and lids.  Just have to research basket, a topic for a different post and I am forcing myself to not get distracted by this premature acquisition and practice with my tools. For now, the main spring will not get attention.  After I put the watch together and running, a small miracle, I don't think the main spring to be a major detractor for practice.  My plan is to have my watch maker service my main spring.  Support local small business and he always shares knowledge when I visit.
    • Hi Ammar, I couldn't find anything about the chemical resistance of PLA to naphtha. According to these sources it doesn't rate too well. I think that your concern is correct. If you did a final rinse in IPA after the parts are out of the basket my guess is it would be fine. I have no affiliation in either of these companies. https://prusament.com/chemical-resistance-of-3d-printing-materials/ https://www.filamentive.com/chemical-resistance-of-3d-printing-filament/
