Need crown size for casio 4004 sg


Recommended Posts

Maybe post a photo of the front and back of the watch? How is it that you know the p/n for the stem and not the p/n for the crown? You ought to be able to measure the OD of the threads and count the number of threads and come up with a reasonable guess on the required threads and then see if you can't find a donor watch.

Thanks for the reply i got the stem part number from the data sheet for the 0903a movement but unfortunately the crown isn't a listed part, probably because its a case part I'll post a photo like you said.

Well, that case back says it's a Seiko. Is that of the same watch? I thought you were looking for a Casio part? It seems there are a number of Seiko guys with YouTube channels - probably some Seiko guys here too. You might have better luck sourcing the stem/crown as one.

    • Hi Bob, Welcome to the forum and thank you for your service.  I would never try to discourage you from getting into this wonderful hobby/profession, but please be aware, it does not cost just a few dollars to get into watch repair.  Tools are expensive and in many instances the cheap knockoffs are worthless, especially when learning.  You can get the tools needed to disassemble, clean, inspect, reassemble and lubricate a watch without spending thousands, but as soon as you start getting into task-specific tools, there are so many and they don’t come cheap.  My suggestion is to start with the basics required to disassemble, clean, inspect, reassemble and lubricate only, and build upon that gradually as the need for other tools arises.  The advice above regarding starting out on working movements is gold. Many of the non-running watches on eBay have been bought, tinkered with, deemed too difficult and then sold again, often with more damage done each time.  Without experience, you clean and service a non-runner and it still doesn’t run. What now? Troubleshooting is difficult as a beginner. This can become very frustrating.  I would encourage you to buy a working movement, and learn to strip and service it. If it isn’t running afterwards, you know it’s down to you, and as long as you didn’t damage anything you know that the parts you’ve got can form a ticking watch. An excellent movement to start with is the ETA 6497 clones from China, such as the ST36. They’re not expensive, and although it finds use in some larger wristwatches, this movement was originally designed for use in pocket watches, so everything is larger and easier to see and handle.  Once you can service a new ST36 and have it running better than it did when it arrived, you’re definitely ready to step up to working vintage watches and then think about repair of non running or poorly running watches.  As far as cleaning solutions go, you will not do better than the commercial watch cleaning and rinsing solutions that are available. You’ll find plenty of suggestions for home brew cleaners online, but the professional products are superior and you want to give yourself every advantage you can, especially when you start working on vintage movements containing hardened decomposed lubricants and often years worth of other dirt and dust. Alcohol is ok for cleaning or rinsing movement parts that don’t contain any shellac. The pallet fork and roller table contain jewels secured with shellac and will tolerate a rinse in alcohol but not prolonged exposure. Methanol dissolves shellac faster than ethanol, and isopropyl alcohol dissolves shellac slower than ethanol. Just in case you don’t know already, the radium on the dial (and likely the hands) of your Dad’s Elgin is highly radioactive. It is safe enough when safely contained within the watch case, but the moment you open the watch and especially when handling the dial or hands you must take precautions against inhaling or ingesting any radium.  Best Regards, Mark
    • I have both sets and use the K&D 99% of the time.  Yes, you have to be careful with the pin.  I use a screwdriver to carefully release the pin from the spring.  Some skill is involved.   I have also modified/replaced the pins in the arbors as necessary.  Yeah, you would think a tool would not require modification, but such is the world of watchmaking.  There is no perfect tool.  Each watchmaker must the tools to his skill, or vice versa.
    • I have the 8-11mm K&D but it doesn't do a great job with modern mainsprings, or I have had terrible luck. The arbor pin protrudes too much and I have damaged more springs trying to disengage the arbor than I have successfully wound and inserted. It seems easier to use with old carbon steel springs. My Watchctaft set gets far more use, though I have to get creative to wind left hand springs
    • It depends on what the gaskets are made from but silicone lubricant should work.  Spray or rub on a generous amount, put in a sealed bag and wait a couple of days.  Test for softness and wipe off the excess.  
    • For hardened gaskets, an experienced watchmaker told me he usually found heat to be the best to soften them up. I tried that on a '70's Tissot where the gasket had turned to essentially epoxy to no avail, but eventually got it off with a 5700 case back opener using a crowbar for leverage to turn the wheel.
