I have a cool old Wyler Incaflex Dynamwind Heavy Duty Dive watch that I found at a thrift shop a few years ago.  I love the watch, wear it all the time and found a few nice JB Chanpion bracelets for it.  My question is this, the bezel moves freely, and upon popping the bezel off, I noticed that there is a channel that looks like it holds a spring of some sort.  Any ideas on the type of spring?

It might be for an o-ring too, just to provide tension... Did you try that?

Unless there is a click or some other feature to the groove, I don't think a spring would do a whole lot for you.

No, I had not thought of an o-ring.  I was looking at an image of an old Tudor Sub and thought that the flat spring or tension ring, what ever it is called, might be what is needed.

Well theTudor/Rolex flat washer spring places upward pressure on the bezel ring which is snapped over the crystal retainer. They have parallel angles so you have to press down to compress the washer to reduce the friction between the parts to turn the bezel easily (when it’s clean and working properly). Brilliant simplicity but rather easy to foul up. My 5512 below shows the retainer without the bezel ring. I think you can see the back angle under the edge.

that groove you show wouldn’t work for a system like that. What does the corresponding interior of the bezel ring look like?

So what retains the bezel now? It looks like a fine groove in the ring and retainer. 

Min that case I think an Omega style spring- fine wire shaped into a hexagon- might be what’s missing. But if the bezel does not fall off, I don’t see what holds it?

Heuer uses the stop sign spring too.

It snaps on.  It rotates freely.  I'm not sure how it stays on the watch.  It takes some pressure to pop it off.  There is probably a slight lip on the inside of the bezel that snaps over the retainer that fits over the crystal.

Interesting. Those hexagon springs hold the ring on in the Heuer and Omega designs. 

If it’s secure, I’ll default to the o-ring I originally suggested. The original probably dry rotted decades ago. 

What is the od of the retainer and the id of the ring? That’ll give you an idea of cross section. The od of the ring gives the id if the o-ring.

I'll check the ID and the OD when I get home.  

 

The crystal has the Wyler "W" in the center of it.  It is stock.  It is a monobloc case if that matters.

    • I'm a newb who is a bit late to the party here. I've purchased a Horia movement holder clone. And I'm aware that the support pins for the SW500 chronograph jewels can be different sizes. I purchased 0.8mm pins with the holder. These were all that were available at the time. Will these be the right size? Can someone shed a little light on this for me please?
    • That looks fantastic! I'm obviously a little late to the party here. Can you tell me where you sourced the case that you used in this build?
    • If pivot shoulder almost touches the mainplate, you will see lower amplitude and free oscilation comes to stop quicker. Such touching can stop the watch. This caliber is based on FHF, I think. So some parts of a cheaper movement of same caliber might interchange.  Both observation point to pivot worn short, which support you suspect , "worn pivot".  The problem with pivots wear to this point is , though the watch runs, pivots can easily jump out of jewel holes in the event of shock, pivots are actually not touching the end stones.   Classic watch repair recommends staff replacement or elongating pivots. Non classic let's you flip the end stones to have the dome side of end stone facing the pivot end, this will somewhat or wholly  compensate for the wear.  Regs  
    • This watch has a pin end mainspring. It's a blued steel spring and may be the original >100 year old part. As you can see, it is quite set. Can anyone suggest where I might be able to obtain such a spring today? Dimensions: Height: 140 Thickness: 010 Arbor diameter: 340 Barrel diameter 989 (1/100 mm)  
    • Many thanks for your answers: 1. I will clean both of them without risk 🙂 2. Both of the rotate inside their setting but they don't seem to come out. I will clean the cock (and the hole jewels) and I will see if they want to go out. I don't intend to force the setting pushing it out by any means. I only hope I don't need the dismantle the whole cock into all its components...! 3. I won't touch it. Only clean. I don't want to take risk... Thanks again! Thanks for your anwer. Yes, I meant short. In fact there are 2 pictures where It can be seen that the balance almost touch the main plate. The balance only spin freely when I loosen the cock screw and also the bottom jewel setting. I cleaned the exterior jewels on the cock and on the main plate. But I can't take the interior settings.
