Ooops! Hi everyone, I forgot to update this post with the finished watch. So here it is, you'll notice I decided to leave the dial as it was, but it was worthy of a new Omega bracelet.

Hi Jerry and welcome. You have followed the path just about how I would have suggested it. Starting on more forgiving pocket watches is ideal. You have made an investment in yourself as well....confidence means a lot. I guess now after servicing the watch you need to consider what's next. If you decide to continue I recommend the following. 1. Buy some books on watch repair. Amazon is cheap enough and has a good supply and keep finding videos 2. Be prepared to be bitten by the bug...advanced tools can be a bit expensive, but starting out ones are freely available at low cost. 3. You will break more things and lose many parts. I think it took me a couple of years to get reasonably competent with tweezers, how tight is too tight etc. 4. Get a good workspace free from distractions....you can really zone out! 5. Tell your friends, this is the way I got started. Most of my workmates have given me watches for repair/overhaul they get a service for free or parts cost and you get the experience. 6. Your friends will tell their friends and pretty soon you will have s steady stream of watches coming in that would otherwise sit in drawers due to normal retail repair costs. 7. About 7 years ago when I started the dollar was better from here and I used to buy all the older US watches (Elgin, Hamilton, Bulova etc) and practice on these often simple movements. 8. Seikos are usually pretty cheap as well...I used to go for the workhorses and also the high-beats... 9. Always strive to be the best you can be. If something's not right, then its not right. Keep going even if you have to take everything apart and start again (I had to do this many times). Anyway, that's just my thoughts, apart from this you will certainly impress people who would never be so brave and ultimately have the greatest pleasure in restoring something that had great sentimentality for someone who could not afford it to be done elsewhere... Go well. Hamish

If there is no visible notch, you will need a single sided razor blade, a Stanley blade and a case knife. Very carefully press the razor blade into the joint, this will lift it slightly without marking the case, then do the same with the Stanley knife which will raise it a little more to allow you to use the case knife to prise the back off. Please be careful when using the blades.

Whilst trawling for some movement info, I found this site. Has loads of movement data and all in one place. Others may find it useful. http://tech.gleaveandco.com/tech-sheets

I am inclined to agree with Rogart, but there is a repair procedure detailed in de Carle's book "Practical Watch Repairing", Pages 88/89. The broken end is bent over with some heat to form a hook and then a short piece of mainspring is used to link the hooked end to the barrel hook. Not too difficult, but certainly a fix only when a suitable replacement cannot be obtained.

Nope i don't think so. I have seen it done but i don't think it will hold in the long term? You should go for a new spring? The spring looks tired also?

Thanks. Looks even better now. My brother took it apart and refinished the case.

Thanks fot this interesting thread Chris, I really enjoyed it. Cheers, Vic

Bob you have a rather interesting question that can have multiple of correct answers. A very very long time ago I was at a lecture on fun and profit of quartz watch repair. So the individuals explaining about cost breakdowns like what would be the cost to completely service of quartz watch? Or replacing a coil for instance what is that's cost versus an entire movement? If you purchase the entire movement for less than a complete servicing you can just swap the movement. Or even the coil sometimes it was cheaper to buy an entire movement than just the coil. At $15 you really can't afford to do anything at all with this watch if you're making money other than just replacing the movement. So at $15 obviously the watch was never meant to be serviced but I was going to recommend go ahead doing it anyway if the watch would come apart? After all were on a discussion group of people who like to disassemble things and you're not doing this for making a profit so for learning alone it's worth disassembling. Then we have something very interesting the watch company Ronda has technical documentation. So at the link below are two PDFs the first one the datasheet Which has an interesting feature listed which I just going to quote directly from it "Repairable metal watch movement". So what exactly does repairable mean to this company? For that you need the second PDF 29 pages of everything. So everything is interesting way more than what you find in a lot of technical literature today. Basically everything related to the watches listed mechanical specifications, user guide, tools and how to service this watch. So starting on page 25 complete disassembly lubrication parts list. Page 27 all the electrical checks you need to do. Basically everything you want to know about this watch in one PDF. http://www.ronda.ch/en/quartz-movements/quartz-essentials/ronda-powertech-500/caliber/515/

Sorry Mickey. As George says, I will be back in the fold soon. I hope you are keeping well :) Sent from my iPhone using Tapatalk

I completed it.

Came across this whilst trawling for info. Seem to have a large selection of decent watch cases,movements etc. Not used but may be helpful to others searching for that obscure item. In Italian so you may need a translator app. http://gioielliboccacci.it/gioielli_boccacci_lista_ricambi_di_orologeria.htm

I've been busy, but I had to have those 3 finished! They are all vintage diving Seikos (and/or Sport models) and a Casio. I also wanted to make some sort of conservative mods out of the originals. Some have the more modern 4r36 or NH36 movement and some the original and rebuilt 7S26/7S36, the Casio had a Miyota 6M12 that was substituted for a cheapo but working Hattori from a cheapo watch ...now with all the pictures, I can't remember where! Some before pictures: Before: After: No before (but really bad) to have an idea, this is a sample picture of how I get them: and after, the pepsi one is still in progress (fitting stem, etc): Next in line: Some of the hands were from ofrei but they are not always available. They also require some fitting since they tend to go oversize, specially the minute hand. Hope you enjoyed! Cheers, Bob

Just had a look at what I've got over the years, seems I have a few good ones I've forgot about, few Dumont's, rubis and precista's. Need a clean up, not sure the best way but at least I have something to work with
