Hi All

I give up trying to find specs to get cheap crystal replacement. I have a Seiko 5y22-8A08 The glass was broken so I can't measure diameter. The thickness is 1.15mm . I don't trust measuring the inside of the case . I do not want to spend the $15 Ofrei wants, I am looking for a generic cheap alternative . Ofrei list the replacement # as Seiko 295W69LN, but they do not tell you the dimensions. The gasket looks good. 

Anyone know where I can find info needed.

Thanks

 

Tony

you should be able to get mineral glasses cheaply enough that its no problem ordering the size you think it is as well as the size above and below that in case your measurement was slightly off. As chopin suggests cousins is a good source, but i imagine if they can offer glasses that cheaply, others can to, even the branded 'sternkreuz' arent that much more expensive.
The only issue is the thickness is a little unusual, I imagine either a 1mm or a 1.3 would not be noticeably different. if you have any of the glass left position it and judge whether you'd rather have it a hairsbreadth prouder or shyer.

Good Idea I do have a little piece I can use to gauge depth. I use a gauge that was made to measure diamonds ..it is extremely accurate. I guess I could buy one bigger and smaller ...But i rather be able to know exact size I need ...There must be somewhere to locate this info.

 

Thanks

You should. Beside, with flat mineral crystal being $1 a piece, isn't really expensive ordering two contiguous sizes.

It's not the cost so much as it is I like to know and also be able to confirm my measurements. It's an OCD thing

 

Besides in the future when I am looking at more expensive crystals cost may become a factor.

That's OK, your vernier (or digital) caliper will deal with that just fine.

Its my first attempt I am sure once I do a few I will trust the process more.

 

BTW should the crystal rest on top or in between the gasket

Supposedly it will rest on the case edge below the gasket. You won't find a generic 1.15mm crystal, so don't count on perfect top alignment.

I did measure 1.15 But after calling Ofrei I was told the actual measurement should have been 2.5 X 29.5, I assume this glass has been replaced before.. I did find a 1.2X29.5  That should do the trick

      AS2063 - hand setting

      By Mercurial · Posted

      Have you got the pallet fork installed in the movement when you see the train move when using the setting works? As nevenbekriev said, without the pallet fork to lock the train, the behaviour you are describing is normal. If this is happening with the pallet fork installed, you have a problem in the gear train, it should be immobile when the pallet fork is locking the escape wheel.  The fit of the circlip above the pinions on that wheel is crooked in your pictures, it should sit flat up against the upper pinion as in Marc’s picture.  Hope that helps, Mark

      Stem broken - can it be rescued?

      By Khan · Posted

      Hi I got a Jaeger LeCoultre K911 movement, where one of the stems was broken. Part no. Should be 401.  Im based in Europe and tried Cousins but its discontinued. They except to get stem in stock for cal. K916 but will that work? Or Is there a way out to join the ends?

      The part was how it fell out of the movement - the train wheel bridge wasn’t screwed in.    I’ll probably dismantle the part, if I can, to work it out.    The train of wheels ran fine - it was only once the keyless works were installed I noticed the problem.

      Balance staff sourcing?

      By mthomas828 · Posted

      Hello, I am about 5 months into watchmaking and I love it!   The attention to precise detail is what really attracts me to it. (and the tools!) I am working on a 16 jewel 43mm pocket watch movement.   There are no markings besides a serial number (122248) .  The balance staff needs replacement. The roller side pivot broke off.  I successfully removed the hairspring using Bergeon 5430's.  I successfully removed the roller using Bergeon 2810.   Did i mention I love the tools?! I removed the staff from the balance wheel using a vintage K&D staff removal tool  with my Bergeon 15285 (that's the one that comes with a micrometer adjustment so it can be used as a jewel press as well as a traditional staking tool...it's sooooo cool...sorry..  can you tell i love the tools?) No more digressing..  I measured the damaged staff in all the relevant areas but I have to estimate on some because one of the pivots is missing. A = Full length  A= 4.80mm  (that's without the one pivot...if you assume that the missing pivot is the same length as the other pivot (I'm sure it's not)  then A = 5.12 mm...(can I assume 5.00mm here?) F=  Hair spring collet seat  F=  .89mm   (safe to assume .90 here? .. I am sure that my measurement's would at least contain  .01 mm error ?) G = balance wheel seat  G = 1.23 mm  (1.20mm?) H  =  roller staff  H =  .59mm  (.60 mm?) B  = bottom of the wheel to roller pivot   B  = 2.97mm  (3.00 mm?)     here I am estimating  again because this pivot is missing. So my friends, and I thank you profusely,  can you point me in the right direction as to how to proceed? Do i buy individual staffs?  or an assortment?   Since I don't know exactly the name of the manufacturer, will that be a fatal hindrance?   Tbh, I'm not even sure what country of origin this movement is. Thank you!

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      Thats why i asked that question earlier, what happens if lubrication is placed directly on top of epilame ?  As opposed to walled within its non epilamed area . I'm not saying its right, i have no idea , just asking questions.
