I have a Luminox 0201 Blackout and the crown has come out. I have already sent it in to Luminox for warranty (but it was bought from amazon so they did not honour it), paid $150 to get it fixed, so I am trying to avoid another $100+ repair bill to get this watch ticking again.

I bought a cheap spring bar remover tool on ebay a while ago (for $1 shipped), when I swapped watch bands and it broke after the second usage. So I am looking for a kit that would have everything I need for the Luminox (to fix the crown), but also some other watches (Bulova, and some cheaper timex etc...)

Amazon has some kits with good reviews under $20, just wondering what the consensus is here.

Also any tips for doing the repair itself would be great. I haven't taken the back cover off yet...

I am not familiar with this watch but if I am correct then it is a Quartz movement. The first thing to do is remove of the back. I would guess is a snap on back if so you will need a case knife. If a screw back then you will need a Jaxa tool. Once open you will be able to change the battery.

If it was new bought on Amazon then there should be warranty?

Seems to be only 1 official repaircentre which is in the Netherlands...What did they do to justify $150 repaircost...on the repair itseld there is also warranty. Does it need new batteries already?

For changing bands you can use a pocketknife to remove the springbars, a small inflatable rubber ball can be of help opening the caseback if it is a screwdon. When it is pressed, the pocketknife can be of help..It is a normal Japanese quartz movt

Is the watch that you have at the link below? So if you look at the description the back is held on with four screws.Then second link shows somebody taking the back off not the same watch but looks like the back is similar. Then it's very likely you may not have the same movement inside.

tactical watch dot com lists movement as a Ronda

Movement:

Quartz RONDA 515 AIG 6

the stem would have to be ordered from supply house

You won't find a "kit" for fix stem/crown, if you mean a kit to work on watches, then those for sale on Amazon or the bay for $20, are about as robust as your "cheap spring bar" tool.

I understand you have already sunk about half of the watches retail worth in repair, Did they, (luminox) not repair correctly???? I would try to get them to do it, What was the $150 for? I know shipping and all that is a hassle, but watch still should be under warranty. if less than a year. Hope that helps.

And I hate to have to be the one to say it but trying to DIY your watch repairs (as a troubled owner) is rarely a good idea, ignoring the cost of tools... well, with advice you might manage the job fine, but you're more likely to make it worse than better.

True enough if the crown just came unscrewed from the stem it's not that complicated a task, but I'm thinking that from the perspective of someone who was trained and tasked regularly to do that sort of thing. 

My advice? avoid manufacturers, they're almost always the most expensive source of repair. Find an independent or established watch repair business. (one that makes a point of doing repairs on site)

If I understand your problem correctly the internal part of the winder has come unscrewed from the external part of the winder? (it's a bigger problem if it has snapped off) There's no reason you couldn't get them re secured for a small fraction of £150, I'm thinking anywhere between £20-50 depending on how highly the watch repairer/business value their service/time and what kind of guarantee they offer.

Sound advice Ishima, but not if he sent to mfg and watch was still under warranty,(FBN seller?) which it sounds like it's not, ( I mean a buck and a half for stem/crown?) me thinks there is more to story here.

Original post wasn't too clear,

I had batteries changed locally twice and had issue with sporadic time, sent it to Saltzman Watch in Rhode Island as they were the Luminox authorized repair center. Warranty was not honoured because it was bought 3rd party on amazon. Repair bill was for new battery and replace stem and crown. It was about $100 + shipping, so about $150 for me, don't have the original bill handy right now.

It was fine for about a year, then the crown came out, it was outside the warranty to get it fixed at Saltzman, and I didn't want to pay another $100-150 to fix it again, so it sat in a box.

I disassembled the watch, re-attached the crown to the stem, gave it a cleaning. When I go to re-insert the stem, it's default position is the day change function. So just rubbing against the crown it will turn and adjust the date.

How do you position it so by default, the crown doesn't operate any functions (date/time)?

All else is good right now. Attached picture of current status.

Ok, thought I had the placement right, reassembled everything and now the crown has unscrewed from the stem again.

Are we to use loctite on the stem? How do you prevent the crown from coming unscrewed? This is a pretty bad design flaw.

Yes you use Loctite on the end of the stem in the crown to lock it in place. Just be very careful that the Loctite isn't protruding out and somehow gets into the watch.

Most everything you want to know about the movement in link, sorry about the misunderstanding in original post. Ronda makes good movements, not great, but good.

JohnR725 is correct about the Loctite, you may want to check and see if the threads are stripped, I'd give the guys at Saltzman a bad yelp!

Good pic of watch too! Helps a lot in answering you questions. Please give update or if you need more help.

if an installed stem doesn't operate properly it's either a fault within the movement or that the stem was originally made too short as to not correctly engage. (this can happen only after re fitting the two pieces together for the second time)

How are you going about refitting the two pieces, without a pin vice you're almost certainly not screwing them together tightly enough, thread lock may or may not compensate for this. 

And to re iterate this needn't go to an authorized repair center, only a competent watchmaker.

i held the threads with pliers (not too tight) while screwing the crown on by hand. applied some loctite and it's currently sitting right now.

As a fallback if this doesn't work out, is the stem a universal part that a local repair shop should have, or do they have to come direct from Luminox? I understand the crown is probably unique to Luminox.

Loctite requires clean surfaces. Then we commonly toss around the term Loctite as an individual substance it's not. Comes in a whole variety of formulas with different strengths different properties you do need to have the right one.

I had a blue semi-permanent one (store brand) that was 2-3 years old, maybe it is no good anymore? but it didn't seem to cure at all. crown still spins freely. are we supposed to use the full permanent one? I find it odd that loctite is the only thing holding the crown on. Would make more sense if it had a locking mechanism of some sort.

I don't want to have to constantly worry about this crown falling off randomly either.

Is contact cement a better option?

Posted

Almost every watch conceived has just used a simple thread system for securing the crown and stem, the tight friction fit made when held in a pin vice in the right hands is much greater than any force applied when setting time and date. It's simple but done by someone who knows what they're doing, it's also perfectly adequate. Many repairers dont even bother to use any thread lock (a small mistake in my opinion, but im saying this to make a point) 

The design isn't what is at fault here.

On the bottles a Loctite we have it work I've seen a expiring date although ours have gone past that. Then if you go to Loctite website you find out that thread locker which is what were using is a anaerobic adhesive which means it hardens up in the absence of air. I'm giving you a link to the website they talk about this notice the reference to metal ions? I was under the impression Loctite basically needed metal as a catalyst with the absence of air to harden up.

found what I was looking for so works on active metals their definition is brass and copper. As well as passive metals  stainless steel and plated surfaces. I notice it doesn't mention steel such as the stem itself. Normally crowns are made out of brass as yours is large I was wondering if it's made out of aluminum?

Good link John I will read with interest.

I have been using Loctite 603 for the crowns for a few years now with no issues. Maybe its not the correct thread size or grease was present before application. I have read 638 is even stronger but it really should not be necessary for a crown.

Posted (edited)

I use Loctite Threadlocker 248 (available from most car-part/bike-part outlets) which is a blue coloured paste in a small tube like a lipstick

As with all adhesives, utter cleanliness is essential.  Make sure you thoroughly clean the threads on the stem AND inside the crown to remove all traces of grease/oil. Make sure they are fully dry before applying a small amount of adhesive.

If the clearances in the stem/crown are bigger than normal then it may take more than 24hrs to fully set.  Make sure you screw the crown fully onto the stem as this will then close-up the threads to minimize the air gaps and quicken setting as the adhesive sets in the absence of air (ie anaerobic).

Ok so I applied high strength loctite to the threads and the crown is secure, now the issue i'm having is the stem doesn't lock in to the mechanism. any tricks to this? i've been rotating it and it does not lock.

Posted

Ok it's finally fixed. Luckily the loctite didn't fully cure, even though it was untouched for 24hrs?? but with pliers on the threads I was able to back off the crown enough so it would engage the lock in the mechanism.

Lessons learned :
-Do not thread the crown on the stem until you feel resistance. There is a fairly precise position it needs to be to engage the lock mechansim in the watch and ensure that the crown is not sticking out to far on the outside of the watch.
-Loctite red 271 doesn't fully cure or doesn't work well with small threads?... (I'm probably going to return this). i was expecting something like this :

Actually you shoulthread the crown onto the stem until it is tight. If having done so the stem won't then engage in the movement then it is not the correct length. Geo has done an excellent walk through on fitting a new stem to the correct length here;

The issue of the crown coming loose is a result of not being able to fully tighten it on the stem in the first place.

Then Saltzman's screwed me over and used a short stem.

    • You shared this test with me a few months back on a Hamilton project and so I had checked this watch to find the pins were still equally spaced. Their screw slots were undamaged and very tight hard to move so maybe no one has messed with them before. I can't work on it much today but I did measure the fork slot again and it seems like 0.44 is the right size. I measure the jewel that had been installed at just 0.42. would an undersized too narrow impulse jewel impact the impulse drastically? I ask because I have had it at a state where flipping the fork manually with a tool would unlock some of the time, but the balance was never capable of unlocking.
    • This was what I was afraid of. The movement is not one of the generic black square modules. Remove the movement from the clock and try prying it open very carefully, without breaking the plastic tabs. The plastic might be brittle from age. Clean the wheels and check the battery contacts for corrosion. Check the PCB for bad solder joints. Take plenty of photos along the way.
    • One of the problems with trying to Photograph Phils things are that his enjoyment was building these things so they tended to E falls on what will see if I can find some earlier pictures or any pictures I wasn't even sure because I was looking for that specific picture for somebody else and even it got the last version and that would have been the last version. You will note that he put the indexing on something that he could unscrew it or whatever and it can slide back out of the way so the rest of the lathe can be used as a lathe. With the lathe cut are actually coming down from the top I was there once where he demonstrated how to cut a pivot with the setup it was really beautiful. Older set up if I remember it's not a worm gear assembly in the thing in between the stepping motor and the holding block I believe this particular one was like a 100 to 1 gear ratio. Earlier version with watchmaker's lathe. Even looks like he is the watchmakers bed and then switch to something he made. Then I do have other pictures and things of the rotary stage in use. In the raw so if you tube videos here is an example of one were somebody's mounting a three jaw chuck. At one time there were available on eBay they were not cheap but if you're patient like I was I found one cheap on eBay. After you watch the video it look at his other videos he is a whole bunch of other examples of the same rotary stage. That I do know there are other pictures examples and possibly videos you just have to track them down. One of the minor issues of finding this particular tech sheet for the unit is I believe it was a custom manufacturer and the company change their name but I remember the new name here's a link to the company https://www.ondrivesus.com/rino-mechanical-components                
    • Escapement adjusting always interesting and depending upon the reference always confusing. Okay maybe it's not always confusing but it does lead to confusion. I have a PDF below it's actually a whole bunch of separate stuff including a hand out that came from a lecture that's on you tube. Then from that we get this image Consequences of doing things especially if you do things out of order or you do things for the wrong reason. Oh and even if the watches working I made the mistake one so showing my boss how tweaking the banking pins on a full plate on the timing machine made the amplitude get better and now he thinks that's what they're for and I don't think a fully grasped exactly what horn clearance means. Consequence of doing things. Notice what it says about opening and closing the banking pins and total lock? So yes I've had that on a full plate where it won't unlock at all and that's the banking pins or a combination of things basically. So banking pins unfortunately get moved. One of the ways to tell if it's been moved is the look straight down at the end of the fork with the balance wheel removed. Power on the fork push at the one side look at it push it to the other side also look at it and compare anything with the center reference the balance jewel and see if both sides of the same. No guarantee after the same there in the right place but at least are the same typically when people play with things one side will be way off from the other because they had no idea what they were doing at all because of course it's a full plate and you really have to paying attention and even then there's still hard to do. Then the other thing that comes up like it shows below is people often adjust the banking pins to do all those other things as opposed to horn clearance which is all that it's therefore and maybe bonus Guard pin clearance although you're supposed to deal with the guard pin is a separate thing like single roller gets bent in Or out or sometimes physically gets moved in and out. Some full plates older escapement's typically pallet forks held together with screws and you can actually unscrew and move the entire assembly in Or out more complications to deal with.     Escapement handout wostep nscc.pdf
