As a complete novice I am somewhat nervous about offering tips to you experts. However I had occasion to remove the caseback from my GS Mk2 pocket watch. It is so well machined there is virtually no visible joint to put a blade in without scratching it plus I did not know if it was screw on or not. I was thinking I needed a suction device which I don't have.

After a few vodkas I came up with the idea of using the suction windscreen mount off my Garmin sat nav. It worked a treat. I also used it on my stepdaughter's Rolex ''replica'' which is tiny and has the authentic style Rolex caseback.

I'm sure you guys have tools for every occasion but this tip might just get a hobbyist like myself out of trouble.

I had a similar brainwave for a different problem. There is a watch called the Seiko UC-3000 which has a battery that is a bit large for the design and is a very tight fit. The temptation to use an little leverage to get it out is great, but it sits in the middle of a large coil. Half the watches in this family that don’t work you can bet someone has damaged the coil trying to change the battery. Little suction cups for 29p iirc from my local shop did the job. Plop one on the battery and you can get enough pull on it to get it out without damaging the coil.

I have one of those cheap “sticky balls” that I use to start Case backs. It helps avoid cross threading as it limits the pressure downward as you rotate. 

The dies tend to want decent pressure to stay engaged and that is more than a tiny lead-in thread should see. 

The sticky ball allows rotation with little downward pressure. 

Start by rotating backwards (unscrew) until you hear the click of the lead dropping in. Then screw it on until snug before switching to the die to snug it up fully. 

Another case back tip for stubborn ones is to invert a can of duster air so the super cold liquid comes out and spray the back until it Frost’s up. Then quickly get the die on there and start unscrewing. This worked for me with a titanium back on a titanium case. That stuff loves to gall.

    god show;   also,  after "the click" or if you don't hear a it.  before you start the screw,  look to see if the open edge slot is even all around the case.  vin

      Epilame / Fixodrop

      Yes, I was referring to the (jewelled) gear train with HP (most of the time, I use 1300, but when Rolex says 1000, I'll use 1000).

      I suppose it would depend upon what your lubricating with those? for instance what does the manufacturer say about those lubricants? I have a PDF from the manufacture and a rather peculiar statement found on the bottom of the chart. my suspicion is the reason the recommending would be without epilam the HP oils like the spread except when they're in Ruby jewel's with steel pivots. tableEN lubrication 2020.pdf

      Is this a 'hack' ?

      By oldhippy · Posted

      These types of hairsprings become weak with age and very fragile. Which I expect it is that giving you trouble, and that wheel is not the correct one, if it were not bent I don't think the movement would run as the teeth are not the correct height. The problem you have is price which depends on you. It can be repaired but is it worth it to you, because there is little value in the clock. A wheel can be made and hairspring replaced. Or hang on to it and keep looking on ebay which is your best bet for replacement parts or even a complete movement but it will be like finding a needle in a haystack.

      I did that also for a few movements - well, mainly in/around the train jewels. I made big efforts to epilame the mainplate WITHOUT getting Epilame into the Pallet fork jewels (where it's not supposed to be, right?). I made litte barriers with Rodico around that jewel and used drops from a syringe to apply on the rest.  However, I've now stopped doing this. For three reasons: 1. It's a hassle and consumes more of this liquid gold. 2. I didn't see the need when using HP1000/HP1300 lubricants and grease for most part. The two places where I'd use 9010 (i.e. escape wheel and balance) receive Epilame in specific places... or the cap-jewel-setting of the balance suspends the oil sufficiently be capillary action (see my "conflict" about using Epilame on the balance jewels).  3. Lastly, and here I really wonder about yours and others' experiences: I felt that applying Epliame to the train jewels left them looking hazy (borderline dirty) compared to the (painstakingly achieved) sparkly clean results of my cleaning process. I just can't help but think that the Epilame residuals would mix with the oil and cause more friction/wear. I don't know.    simple: it'll stay there. It won't move any further. That's exactly what is happening if you epilame a cap stone. You end up placing the 9010 right on top of the epilame and the oil will sit nicely on that spot.
