Hi. I'm looking into having a go at disassembly and hopefully rebuild a movement. I've came across a Ronda 1113 are these good for a beginner to try with or any suggestions? Budget low. Thank you

Old movement probably been sitting idle for long time, I soak the movement in naphta   for a day or two or apply penetrating oil which  reduces risk of breaking screws . Take extra care with pin pallets. Not worth buying parts for, I got some parts to it.

For a newcomer the skills you'll be needing to pick up are to do with dexterity in handling small parts with tweezers, undoing screws and making sure the screwdriver blade doesn't slip, cleaning parts, reassembly, putting the balance back in place etc. etc.

You don't want to be starting out with expensive movements and so pin-lever designs (like the Ronda 1113) are ideal as they'll introduce you to the makeup of a watch and allow you to practice the above skills and can be picked up pretty inexpensively.

Initially I'd advise getting hold of a working movement. This way you can concentrate on the important dexterity skills and disassembling and reassembling with the aim of the watch still working afterwards! The danger with picking up a non-working movement - especially on cheaper movements with limited shock protection and jewel counts  - is that the balance staff can be shot or parts worn which then means you have to get other movements the same for spares or new parts which outweigh the value of the movement.

So in summary I'd say the actual movement you chose is less important than getting something that works already and/or where there is good availability of other 'spares or repairs' movements the same so if something goes wrong you have a parts backup source.

Thank you for reply. the Ronda 1113 is sold as new old stock. Working and at only £8.50. I will pick one up and practice. Thank alot.

For a newcomer one thing to be careful of is squeezing the tweezers too hard when holding a small part, quite often the part will 'ping' off at great speed involving much searching. Basic stuff, but you don't always think of it at the time.

Thanks for all your help.i have only changed crystals,hands and whole movements before so thought I'd have a go.

Therefore, see that you always have a magnetic strip around, to find the small pieces on the ground again.:biggrin:

And don't forget them to demagnetize afterwords.;)

    • 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.
