omega 751 continues to irk me


Recommended Posts

Hello,

I got the new incabloc spring and it fit perfectly. Some may remember from my last post, that the other one seemed slightly too big and it was.

 

Now there is a new problem, the date will not turn over by spinning the hands past midnight. I think its a problem with either the double calendar setting wheel (560-1559) or the date indicator driving wheel (563-1564) because I can see the date indicator wheel reach the teeth on the date wheel (the one with the actual numbers), but it stops as if it doesn't have enough power to turn it over. I also crushed the tube of sweep second hand trying to tighten it so that it wouldn't spin, but its no good now! I need a new sweep second hand and cannot find a S.S. one.

 

Has anyone had the problem of the date not turning over at midnight like this?

 

Thanks for any insight anyone can provide.

The date wheel itself seems OK. I mean, It worked before and it was just wrapped in tissue, and I was waiting for the incabloc spring to come before putting back the calendar works. The date will change only by quick set: which uses a "work-around" little hook that physically grabs the wheel and spins it. But via the usual way, the date indicator gear meets the date wheel and stops. The watch keeps going.

Hello

Thanks Bob. Yeah I've checked O Frei. They have the blue steel, pink gold and yellow gold for the 751 calibre,but no stainless.  I've tried the hands that fit the 750 and 752,but they do not fit the 751--the post is too long on those hands. I've ordered a  generic set from ebay once again in the hopes that I can somehow make the sweep hand fit. I've tried before but did not attempt an alteration. Someone told me I should have tried a broach, but I can't find one fine enough to use.

That will be my last chance effort: buy a gold hand and have it replated in rhodium. I can have it done using a Canadian company I've used for 2 of my watchcases, but not sure if they can do a sweep hand as it will need to "wired-up"  to plate. Do you think I could sand the gold off? I Thought maybe they were....well,  I guess gold colored throughout?

That was my first thought. But never with a gold hand rather the reds or any of the painted ones. A dip in acetone or some other chemical and maybe a light sanding? Experimentation is on! :)

I would try it on first regardless of color and see if they fit the watch the proper way though...then if OK, you'll be good to go.

Aren't the hands made in brass? If so, you can rhodium! Otherwise they will not turn white when polished.

This is the last time I post on this darn Omega watch. I had to replace the cannon pinion and center wheel ($$$) because it was not running properly. This is the 3rd cannon pinion I've bought! True, I ruined the first two by over  tightening them, but its been a tramautizing ordeal with this constellation.

 After taking the watch apart for the 4th time, I looked closely at the clearance of the center wheel and slowly rotated it in is jeweled setting. I noticed a slight warping...probably when I was trying to fit the cannon pinion I over tightened. This warping was causing it to skip and at times rub on the mainspring barrel, causing the movement to stop. Ok ordered a new cannon pinion and center wheel.

Well, I also ordered a new sweep second hand--yes it seemed too small again, but this time I took a very fine needle and opened it up. I pressed it in place while holding the sweep second pinion carefully from the other side and it seems to be working. I cleaned everything again and its sitting vertically on my workbench right now

I don't think I like this watch anymore! I look at it with disgust and resentment for what it put me through. I'm really thinking of selling it, but I've put so much time and money into it! I am afraid I'll wake up and something else will go wrong, and then the next thing....and the next thing...and the next! Over and over like in some late night Twilight Zone episode where the guys winds up becoming a lunatic because the watch drove him mad. I'm gonna sleep on it before deciding. I'lkl have to sell it for parts at this point--whether it running or not. Has anyone else been torn between selling a watch that has become a headache, or keeping it regardless because of time/money invested/sentiment?

IMO, it's a gorgeous watch with a beautiful movement and a very nice dial... If it all works, put it back in the case, put a nice band on it and keep it.

If you're on the fence, sell it. It's sad to have a watch you'll never wear just collecting dust in a drawer somewhere.

 

PS: if it's helpful, please note that I gladly take Omega donations :P

Thanks Frenchie!

I know I said I wouldn't post anymore on this particular watch, but....dont be mad at me @Mark, I just can't help myself! I've put her back together as carefully as I could and decided to give it one more chance. I'll see how she performs today when I take her out...so far so good.

Beside that I don' particularly like this Seiko-5 lookalike, watches are inanimate objects, no need to develop feelings about'em or keep fighting trophies. At least from a watchmaker perspective.

What matters is that you certainly learned many things in working on it, and hopefully got it right at the end, hence building up your patience and self-esteem. That alone will more than justify the money spent, even if you have to sell it at a loss.

Many watches look like one another.  I guess which looks like which would depend on who came with the design first: probably Omega although I don't know for sure.

Just an inanimate object? I disagree with you on that quite vigorously! This is an instrument with its own character and energy--certainly no mere inanimate object such as a chair or table; and even those can have a warmness and comfort that imbue them with distinct qualities especially if you made it yourself. Surely you've owned a car, bicycle, toy or some other object that you treasured and had "feelings" for?

In any case, you're correct in the lesson that this watch has taught me. The Omega has been keeping great time and everything is as it should be up to now. The lesson? Perseverance!

Hi Noirrac,

Can you not re-rivet the calender driving wheel?

 

Anil

That's a good question Anil, and one that I didn't even formulate when the problem arose. The wheel itself is tiny and beyond the realm of repair to my eyes. Perhaps someone with the right tools and skill set could repair it. Do you need the calendar wheel? Its yours if you want to try repairing it.

Be reassured that I understand perfectly what you say, it's just like that for me watches like any other beautiful objects are.. objects.

Of course I had many toys that i loved, but they were just toys. The feelings I've experience living with them will stay with me as I live or recall memories, objects are mere enablers. Think of Leonardo di Caprio and his many young dates: he can't just get too attached :)

And you woke up being a Zombie Killer not a mad watchmaker! I love the result, Joe. That's a nice watch for the collection and I'm sure, after all the tribulations, it will have a special place in your heart...errr, wrist? :)

Cheers,

Bob

PS. Well done!!!

    • Even for myself who only started getting into watch repair/servicing during COVID I have seen a huge jump in watch prices - we have a 404 channel on this forum. When I started you could relatively easily find a watch on eBay to restore and put onto the channel, however this is now almost impossible and the only feasible solution is to buy a job lot with an average price <4.04. Even watches sold for parts/spares are 3 or four times the price of only a few years ago. Why - Either Demand must have increased in order to push up the price, or supply is reduced. I think it is a little of both, I think that most watches in the UK/US may have been picked over, which agrees with most of what @Neverenoughwatches says so supply of all kinds of vintage watches, including tat is dwindling. As a double whammy I think that more people are wanting watches, either to work on, or as a way to differentiate themselves from the Apple Watch and FitBit crowd. The upshot is that half decent watches that require restoration are now $500 instead of $100 and cheaper watches (Seiko 5 etc) are now $50 instead of $10, and even Mumbai Specials and garbage are now pushing $50 each. When - how long will this last, I think that most of the people who are returning to mechanical watches are those that have previously experienced life without them and want to return to something with a bit of personality that doesn't buzz every 10 seconds on your wrist and tell you how many steps you have done today. i.e. the 30-40+ generation. My son who is 17 has several mechanical watches but only wears one on a special occasion and is obviously only aware of them at all in part due to my hobby. I asked him the other day how many of his friends wear a watch and he told me that some use a smart watch but most just use their phones. So as I see it, demand will start to fall once the sub-thirty crowd start becoming the majority and/or the older amongst us stop buying watches and switch our attention to mobility scooters and trying to remember our bank password. Price - I think this is here to stay, even if demand does start to drop as the older generation becomes to decrepit and stops buying and the younger generation isn't interested in buying, supply will become progressively less as time goes on as more vintage watches become lost or broken beyond repair. I think the prices will plateau at some point as an equilibrium is reached as reduced demand is balanced with reduced supply, i.e. less and less people buying less and less watches. Sorry for the long ramble!
    • Hi. Use a PVA based glue, gorilla glue it dries transparent then do as advised by Old Hippy, smoothe down using very fine  0000 wire wool and either French polish or beeswax for a finish.
    • Hello and welcome to the forum.    Enjoy
    • The problem with oil in particular 9010 is it likes to spread. This is why you're supposed to use epilam anywhere it's used to keep the oil in place. Then you want to splurge on money you could buy 941 it's actually an oil that existed before 9415. Then the problem with the grease yes it stays in place but if you have too much you lose amplitude. Then if you get really obsessed with this he would follow Omega's recommendation for escapement lubrication. One of the problems with internal documents of the watch companies is typically are never going to see Them.But a few of them out in the wild for instance at this link Below I searched for the keyword of working. In particular working instructions of the Omega watch company for which there is way more than This but this is all they have. So you want to download number 40 as were going to talk about that and also download Number 81. Plus anything else that looks interesting https://www.cousinsuk.com/document/search?SearchString=Working Then number 40 covers lubrication of the watch. Most interesting is lubrication of the lever escapement under three different conditions with Lubrifar Which you probably no longer have has been washed off without which is what you have and then a course with epilam. Notice how they go supers super minimalistic with the 9415 because if it's too heavy you lose amplitude. Then if you lose amplitude the group will be disappointed with you and the end of the world will come.      
    • You would always get an answer John, you dont need to be dramatic or humerous to get one, but it was appreciated anyway 🙂 Kind of, for those of us that wish to stay in touch and continue to learn from each other in case the forum ever dissappears then yes i suppose so . I  hope that you would also count yourself in , what we learn from you is invaluable,  how you benefit from that exactly I'm not sure, being able to teach ? I did say is it ok to ask mark for some input John and suggested that he might read the thread that explains how some of us feel. I dont see how its really discussing forum policy, but in all honesty i wish i had never even bothered now.
