I'm looking for a replacement mainspring for an old Elgin movement. CousinsUK seems to me to have the best "look-up" feature UNLESS your search comes up empty. The original spring is 0.1MM X 1.25 MM X roughly 270MM in length. this of course turns up nothing. What variable do you start with that is least injurious to the movement and accuracy when you must locate a substitute mainspring. I understand that heaight and length are rather fixed variables. Can I go up slightly in strength without too much badness happening?
Any advice out there for cleaning/polishing watch crystal glass?
I know there are videos upon videos on howto clean acrylic watch crystal glass using toothpaste, Cape Cod cloths, an old toothbrush, etc.
However, I am trying to get a number of scratches out of a watch crystal I have taken the movement out of. It is for me a "tester".
I am fairly sure that this "tester" watch crystal is glass.
I have sandpaper (wet/dry) and I have a Cape Cod cloth which I have just started using.
I think you can see the scratches in question in the pics.
So, what I have done so far is use 400-grit sandpaper to scrub across the grain of the scratches. I have also tried scrubbing in a circular motion.
Maybe I am just not very persistent at this. I scrubbed for some time. But all I can see is that NOTHING is disappearing, and the only thing that IS happening is that now the whole glass is covered in a new set of sandpaper-made marks.
Maybe I can use the Cape Cod cloth to get these out. Maybe I can use the other 1500-grit sandpaper to smooth things out too.
This process looks so easy in the various Youtube videos. yes, I know these things can take time, but HOW LONG?? This is NOT one of the fun sides of watch repair that I am looking forward to doing now or, in fact, any time.
I really thought that it would be the case that - scratches and marks on the crystal? No problem! I can get them out! :)
But perhaps I was naive (?)
How long should I be scrubbing with the sandpaper? Is 400-grit not enough? Should I get more coarse sandpaper?
I own a fake Rolex submariner and the piece that connects the band to the watch is missing. I want to get this piece replaced but I fear that getting a replacement piece from a Rolex store would be way to pricey, and getting a cheap knockoff piece online would be, well too cheap. Is there any place to purchase replacement parts for an affordable price?
Have adjusted it like that. Also removed the jumper altogether to see if the disc would move more, but it didn't.
I measured the diameter of the peg on the driving wheel and it's 0.3mm, is this the correct size?, to me the peg looks a little bit smaller then the other once I see pictured here.
It is supposed to be completely flat, no wobble. If it's not flat there is a risk the disk is not just scew but the date ring also is misaligned to the star wheel. The snappy action during date shift will for sure not work in that case.
A date jumper is supposed to do what the name applies, keep the dial in place with a small force, just to keep it in place only by friction will make the dial move a slight bit with every small chock the watch gets and I doubt even ROLEX haven't made it work that way, but one never knows
