I've Just Landed A Constellation Without Crashing!


Geo

Recommended Posts

I finaly managed to get a Connie to complement my Omega collection, it is a Gold Cap model from 1966 with a 561 movement.  I went against recommended practice of " get high definition pictures and ask to see the movement".  The pictures were not at all good, and the seller said that he had no means of opening the back.  I'm sure this put off a few folk, but luckily my offer was accepted and it turned out well.  I did know that the crown was incorrect when I bought it.  After a couple of small adjustments it is holding 0 to +2 seconds on the timegrapher. :)

 

Here are some pictures I've just taken.

A service should smooth out the graph a bit.

One thing. My info says lift angle is 49° but you have it at 52°.

 

Ooh goody, tech stuff!

 

I looked up lift angle and saw what it was in a good little video on YouTube  - 'Classic Watchmaking: How To Determine The Balance Lift Angle Of A Watch Movement '

 

From what I saw, the only way to change the lift angle would be to restrict the amplitude until the desired angle is reached. I think I understand how that is achieved but could anyone give a definitive answer please?

 

Thanks

John

Really nice Watch, I like the looks of those calibers and casings. You can't go wrong with a constellation..!

I once had a seamaster automatic from the same era. Gold filled with black dial and arrowhead indexes, a real stunner. Sold it about 8 years ago,

something I will regret for the rest of my Life.. :pulling-hair-out:

Nice watch Geo. Piepan?

Hi Roberto, It was advertised as a Pie Pan, but t's actually what Omega term a convex dial.

 

You are correct it does have a 49 degree lift angle and that is the setting I used for the one in the thread on servicing a 561.  I was working on another watch yesterday and too  be honest I simply forgot to set the Timegrapher to 49 degrees.  on an 18000 beat watch it doesn't appear to make much of a difference in the real world, it's still spot on time today.  here is a link to a discussion on another forum that is worth a read.

Thats a beauty Geo , nice find ,i'd always thought of them as pie pan so something else i've learnt today  :)

 

I can understand your confusion Andy because a pie pan looks so similar to mine. On a pie pan the area between the indices is flat, whereas the area between the indices on mine are convex although the style is the same.

Thanks Geo , so do Omega do a pie pan or are they all actually convex dials ?

Thanks for the info Gro very interesting, will keep my eyes peeled

If you're looking for one, it's a bit of a mine field. Do a lot of research that way you're not as likely to get your fingers burnt.

I sugest you start off by working your way through everything on this site, it's invaluable! :-

Geo you've got great taste. I love the Omegas from the 50's and 60's. In fact they were my very first watches in my collection watches before I got into all the other crazy watches of the 70's. I have many omegas but I will share these two with you so that I don't hijack your post! My 561 is a fantastic runner and the 504 is somewhat of a rarity with its arrow head markers and low production number. Enjoy the connie "convex" Pie-Pan and wear it well buddy!

    • Even after thorough cleaning unfortunately the issue persists. I have made sure that all wheels are perfectly clean, no teeth are chipped, no gunk is left built up on them etc. yet the issue is not gone. When reassembling the movement I of course checked if the wheel train moves freely as that was the suspected cause of the issue before. And the intersting thing is - it does - but only in the "wrong" direction. Driving the wheeltrain by turning the mainspring barrel in the opposite direction as it would turn in normal operation, all wheels spin freely, and continue spinning for a few moments even after I stop providing power by hand. They behave the way I'm used to and have seen with other wheels before. However: When I apply torque in the opposite direction, the power delivery througout the train is not smooth or continuous. While it does turn, there are stages of increased resistance in the train. In addition to this, you can hear a slight "rubbing" sound whenever the trian passes by this point of increased resistance. The sound, to me, is more indicative of a surface rubbing on another surface, rather than the teeth of two wheels getting stuck within each other. Installing the click and putting a wind in the mainspring confirms this same issue, it does unwind and all wheels are powered, yet when the power reserve approaches depletion, it doesn't have enough power to push the wheeltrain past this point of friction. The slightest bump on any of the wheels will free the train, make it spin for however many rotations and then get stuck in the same way. You can do this several times before the power is actually completely depleted. This has really left me dumbfounded. I have inspected all of the wheels, pivots, teeth etc. on the entire wheel train and can't find any traces of dirt, any bent teeth or any warped or out of plane wheels. Besides: If one of the wheels was bent and rubbing up against some other part of the movement during a rotation, shouldn't it be doing this regardless of the direction of the rotation? This is supremely confusing to me and I can't figure out for the life of me why there is increased friction in only ONE direction and not the other. Installing the balance yielded the same result as before the disassembly: the watch runs great for about 50 seconds and then get's stuck when the wheel train get's bogged down. I mentioned earlier that there is a periodic scraping noise that can be heard when the gear train turns fast, this noise is not present when turning the train the opposiste direction. Does anyone have any ideas about which parts of the movement I can check for rubbing? I found no signs of wear or scraping on any of the bridges etc. so what would cause this periodic friction in one direction but not the other? I am very much a novice and have never dealt with such an issue before so I would love to hear what you people think about this. Thanks.
    • For me the second site has been hacked. 
    • https://www.mikrolisk.de/show.php?site=280&suchwort=Tschuy-Vogt&searchWhere=all#sucheMarker Wierd the first link didn't work.  They used other manufacturers movements, like most watch companies.  The watch you are asking about has this movement  https://calibercorner.com/ronda-caliber-3540-d/
    • Is there a way to interpret that?  I assume that is information on the watch?  Thanks!
