How do you replace hunter watch crystals?


Recommended Posts

Hello all,

I have a few of hunter-style pocket watches that need crystals replaced.  I am finding conflicting information online and in videos on what to do.  Some say to use a regular press, but some say not to.  Some say to use a Robur press, but others say that hunter crystals are too thin to safely use on one.  Others I'm hearing say to heat up the bezel ring to expand it, place the crystal in, and then let the bezel shrink down and clamp into it.

So far I have no clear answer.  I don't have a whole lot of these, so I don't want to invest too much into a solution.  I also played around with the idea of just getting the largest size crystal that can drop directly into the bezel, and using crystal cement.

Any help is appreciated!

Thanks

I actually like your last Idea as these crystals are not subjected to outside elements as they are protected by the lid.  I have a situation now where the bezel for the Hunter PW is actually not round when installed and so cant fit a crystal....I am stumped.

The easiest way for you is to find a good fitting glass and cement it in. In order for a satisfactory job the glass should be as tight in the bezel as you can get. The proper way and it’s the old way is to first heat up the bezel. Don’t forget years ago the glue that was used was not clear and it would take hours to dry and it left a yellowish colour. That is why heat was preferred.

What about my oblong bezel? Round does not work

Are we talking about a glass crystal or plastic? Plastic Hunter crystals are so much more forgiving than the glass.

Glass.  Normally my go-to is plastic, but as far as I'm aware, anything other than hi-dome plastic crystals don't have the step in them for grabbing with a crystal lift tool, and I have trouble getting an even grip on stepless ones.

I'm still not quite sure on the same page here? We might be on the same page but not sure?

I snipped out an image from the GS crystal catalog. You can see a variety of around shapes including those that have the edge for the crystal lift. As you can see I circled the hunting crystal those are normally paperthin never have a lip as are just too thin.

The best way I found is if it's plastic slightly bigger than its supposed to be to drop in. Using a crystal press you can get it to bow just enough that it will fit the bezel perfectly no glue is needed and if you're lucky can still close the lid of the case.

    • I always pull the stem out either one or two clicks. In doing this the clutch has a little more stability engaged against the date setting wheel and is less likely to flip. It's a design fault ETA should have sorted out by now. The ETA 2892-2 doesn't have this problem! Also when the stem is out don't give the movement any hard jolts, as this sure to flip the clutch and then the yoke comes out of the notch of the clutch. You can sort it out by removing the barrel bridge and reseating the clutch and yoke, rather than removing the dial and hands, etc.
    • Hello,  I have an old (20 or close ) fossil automatic. I don’t quite remember when or why I bought it but I ended up not liking it too much and not wearing it.  Now that I am starting the watch making (hopefully more like breaking right now ) hobby I figured I could get into it see what was the movement and practice on it.  The problem I had was in opening the back. It is held by tiny Phillips head screws most went fine but one wouldn’t come and the cross shape of the head became so damaged from my trial that it was unusable.  With one screw only holding the case I could force it open I am not sure what deformed, the case back hole or the screw head but one gave way.  I could then remove the damaged screw with plyers.  So now my question is do you think I can find a screw to replace that broken one?  Not that I intend to where the watch but I’d still prefer to reassemble it completely including the case
    • I find working up to 1200 grit wet and dry works fine and finish with Brasso. As long as you are light with the wet and dry and let the paper do the work, rather any real pressure put on the crystal. Here's a before and after of this Rolex acrylic crystal I polished this week just using 1200 grit and then Brasso. Circular motion of the lint free pad or bud you use. Personally, I think Polywatch for what it is, is a stupid amount of money for a small amount of abrasive that's very watered down if you compare it to diamond pastes. Before.   After.
