it was me and only 15 seconds or so.Someone used a hairdryer on full power for 10 minutes to remove the crystal - basically involves melting the glue. Not sure how it affects water resistance, but it definitely works.
That is really interesting! Can you please give us a little details on the steps that you took? It would be really helpful to know how to do that so, we could restore the old DW5XXXXs, if we ever needed to...it was me and only 15 seconds or so.
The crystal did use a gasket and glue underneath the crystal. From what I have seen, you can re-glue it anf w.r. should be fine.
Thanks! So, if I understand it correctly, you ran a blow drier to a DW5300 watch case for 10 minutes and then removed the crystal with a towel wrapped around your thumb. Is that right? What direction did you run the blow drier from? Is it from the under the crystal or on top of the crystal? Any ideas to what type of blow driers we would need? Please let us know. Thanks for the insight...I did it on a dw-5300 and the crystal is quite thick, 2.0~2.5mm or so and nothing special really, I just heat it for a while, wrap it with a towel and use my thumbs to push old crystal out from inside, again use thumbs to press new crystal in. No crystal press was used.
I did not clean off the glue because it was still in good form so I just install new crystal on old glue. After case cool off, can not remove it with bare hands.
I think WR is basically done by gasket and the glue is more about holding the crystal to the case...
well, maybe 60% of its existence but don't hold me for that.
