Bezel spring replacement ft. “What makes the click.”

A friend gave me this battered cheap Sub replica to play around with and I plan on re-purposing the case for something else with a new movement, face and hands.

I decided to pop the (rather slack) unidirectional bezel out to tighten the spring a little and also to remove the ceramic insert and replace it with something a bit less ‘Rolex’.

Anyway, I can’t figure out what makes the ‘click’ sound?
Should there be a part located in the hole indicated by my tweezers? Or is this a universal case that includes that hole to accommodate a flat bezel spring as an alternative?

Thanks in advance!

Ugh. These reps are always a mess to work on. 
 

I believe the click is provided by the octagonal spring. The funnily bent end probably goes in the hole and the other end bears on the “teeth” in the bezel ring.

That would make sense BUT, the spring goes in a recess in the bezel and the hole is UNDERNEATH the bezel. I assume there may have been a bearing a tab sitting in the hole. The ratchet surface is under the bezel.

This is an inexpensive Chinese replica.  Put yourself in the mindset of a mass mass producer of these.  The Chinese will default to the simplest cheapest method of doing something.  Don't complicate it in your mind.

 

The dog leg in the wire goes in the hole, the wire wraps around.  The straight end of the wire provides the one direction of turn.  It could be easy to get it back on or it could take you hours to tease it into place.  The one I did still had the insert in place and it was fiddly to get everything in place to install.  I think I put the dog leg in the hole, tilted the bezel and got the wire started in the grove, then turned the bezel while pushing it down into place.  The parts involved on mine were the wire and the bezel, that's it. 

Just keep it simple, that's what the manufacturer did.

I like your thinking but the serrations are on the underside of the bezel so it must have been something sticking out from the hole that made the click. It appears the hexagonal wire just stops the bezel falling off.

It definitely wasn’t this method. I’d have noticed something this big!!

After watchweasol's comment and few google searches, now that I see that big empty hole next to your tweezers i'm quite convinced you're missing the ball bearing.

The ball will allow it to click in both directions.

It may have been a wedge, with a spring under it. Is the hole definitely round, or does it have some feature to is, such as a slot?

I had a fake seadweller with two balls with springs and one "wedge" with a spring. The wedge was damaged and I had to reshape it in my case.

I've only been into one of these.  All that was there was the wire.  It could be that one end of the wire has broken off.  Mine had a 90 degree bend in one end that went into the hole.  The other end kicked out a little to engage the serrations.  It was that simple. 

Is there a wear mark on the bottom serration?  No wear marks, no ball or click spring.  Find the wear marks and you will find the method for the "click" .

The wire sits in a recess within the bezel. The serrations are on the underside of the bezel, passing over the hole. I don't see any way you could locate the wire in the hole and also have it seated within the bezel recess. It must have been a small section of wire or a ball and spring acting on the serrations. My money is on a wire because it was uni-directional. I fashioned something out of a paper clip (below) last night which had the desired effect but was to thick to allow the bezel to seat flat. I'm going to destroy a biro tonight ?

I have heard that you can't remove these bezels without destroying them.  There is a possibility that the wire broke from this or a previous attempt.  You are forcing me to fiddle with my Parnis to compare notes. 

A complex bend in cheap Chinese wire has a high likelihood of not working out well.  Any chance you can examine the ends of the wire?  Look for evidence that it was cut, filed or broken.  Broken will probably have a grainy look.  Cut or filed will be shiny.

I stand corrected.

Now I have to fix my bezel. Was hoping to make it uni directional but not possible.

Looks like we’ll both be destroying a biro then doesn’t it!!! To be honest, I think I might pop into a bearing supplier and find a ball bearing that sits snug. All my ballpoint pens seem too small.

Birro is English english for ball point pen?  Those will work but the ball is tungsten and purposely rough.  It will eat up the bezel.  I have replaced the 1mm ball in several Seiko watches.  I bought a 100 count bag of 1mm stainless steel ball bearings on amazon.  This is not the same.  It is a spring loaded plunger with a pin in the center.   The pin is close to 1mm and the plunger is maybe 2.5mm?  I didn't have my calipers out and I already put the bezel back on.  Sorry about that.  Should have measured it.

 

You can see the spring in the hole in the first picture.  A watchmaker could probably turn one of these in 5 minutes.  I could see using a piece of brass rod and drill the center.  1mm SS music wire, nicely rounded.  Still thinking on where to get a suitable spring.  It was about 3mm high, maybe 4mm. 

A SS ball bearing closer to the size of the hole and a spring may work just fine. 

The bezel clicked back on with finger tip pressure for future reference.

Yes, Biro is a brand of ball point pen. 
If you have a spare spring bar, you can remove the spring from that and cut it to size.

The spring in there is much larger than any spring bar spring.  My watch is back together.  The spring in a Seiko diver is much stronger than any spring bar spring.  I have used both on projects.  The Biro ball and spring bar spring get the job done but are nowhere near factory parts in strength rating.  One genuine Seiko click ball and spring will set you back $15.  I got a 20 pack of springs and 100 pack of BBs for less than $15. 

The plunger is to the right of the hole, on its side, in the first picture.  It is installed in the hole in the second picture.

      Movement inserted from crytal side

      By Jon · Posted

      Put the movement in a movement holder and it will be supported as you push down on the setting lever post to release the winding stem. Make sure the post is over the shoulder of the movement holder so what you are pressing down on is supported. As a general rule, hold the movement and not the movement holder. Replace the hands when the movement isn't in the case and support the centre jewel (if it has one) on a hard surface or staking block when replacing the hands to stop the jewel accidentally moving or even coming out. A dedicated movement holder with a central jewel support is even better, but pricey

      It might help us if we knew which watch like model number.

      Movement inserted from crytal side

      By Zedster · Posted

      Hi, guys I have a bit of a predicament and hopefully, somebody can advise. I'm working on a Roamer MST 521 where the movement is extracted from the crystal side. I'm now at the final hurdle where I need to replace the movement back into its case but I'm not sure of the correct procedure. I still need to fit the hands but that's where the problem lies. If I insert the winding stem to test the hands for correct alignment I will need to turn the movement over to release the stem again it's the spring-loaded type and needs a small bit of force to push down but with the hands fitted, I don't think I can do this on a cushion without causing some damage to the hands and that's the last thing I want to do, this watch has already been a love-hate relationship and I'm so close to boxing this one off which I'm counting as my first major project.  The other option is to case the movement then fit the hands and hope everything is okay. I've already broken the original winding stem but managed to find a replacement, the last one in stock, so I'm a bit reluctant to keep removing it. Any suggestions would be appreciated.

      Main spring

      By Jon · Posted

      I would go for the dearer spring. You won't need to remove the spring from the carrier ring and then use a mainspring winder to get it into the barrel, for a start. Also that spring is closer to the needed dimensions, especially the length. The length plays a part in the mainsprings strength. If you double the length you will half the force (strength) of the spring and vice-versa. A spring with 20 mm less length would be about 7% shorter, so technically would be 7% more strength, but I find halving this number is closer to real-world findings, so the spring would be about 3 to 4% more strength/force. On a mainspring that ideally kicks out 300 degrees of amplitude, a 3% increase in amplitude would be 309 degrees. Increasing or decreasing the length of the mainspring will affect the power reserve to a greater or lesser degree. It depends how much shorter or longer it is.
