Diesel glass replace

[Nickpan]

picking up a mullered Diesel DZ 1718 'Rollcage' tonight, I've watched dozens of Youtube vids but can't suss if I'll need a gasket or 'glue' when fitting the glass.  I'm not just hoping for the answer, but tips on how I would find this info - ie, is there a parts list somewhere, or a 'blueprint'.

 

Thanks in advance

Looks like it was glued and possibly just a flat acrylic.

[Nickpan]

lovely, thanks.  Superglue do the job?   

[RichardHarris123]

No, don't use superglue, it off gasses and fogs the crystal. The replacement may not need gluing but I don't know anything about the watch.

No, superglue stands a chance of melting the watch and lens.

You want to use G-S Hypo Cement or Jewellers Cement.

Edit

Should have added the irrespective of what was their before and depending on the size you could look at fitting an I-Ring & Crystal.

yes, this is where I'm at - 'sold as seen', I bought it as seen, no crystal or evidence of gasket, and so far, Fossil (who make Diesel) haven't responded...

The first place to start is can you measure the opening and see what size you need?

[Nickpan]

yup, got glass on order

So what are you doing? Glueing, I-Ring?

If you're glueing then you'll need to remove the movement.

[Nickpan]

I can't find anything out, abut I-rings!  Only the Apple product that goes on your finger    I'll see if the right glass turns up and see what happens from there.  I have the correct cement, so I shall be carefully dabbing that on.

BUT.....I can only get the movement in and out through the front - the 'rollcage' element mean I can't remove the stem!  So watch this space, I have to try and straighten the hands, slide the movement in and onto the stem, then cement the glass.  It's my first genuine attempt at a repair, luckily the smashed up Diesel only cost a fiver

Once you fit the glass with glue some is more than likely going to squeeze out onto the dial.

I see what you mean about the stem but if it went in the it must come out somehow.

[Nickpan]

possibly break the loctite on the  stem and crown

There is precious little technical information on fossil or diesel watches, I have tried to find it before and failed.

[Nickpan]

yup!  Got in touch with Fossil, they said it was a 39mm glass, so I ordered one (even though I'd measured it at nearer 39.5mm - but hey, they know best, I've never fitted one before).  Glass plops straight in and is loose enough enough that you can wobble it and hear it tapping the sides of the case as it moves...

It's just a few quid for another, but with the postage on top, that's a tenner down the bog 

[AndyGSi]

What thickness did you get and how sure are you about the 39.5mm?

It maybe possible as mentioned to use an I-Ring.

[Nickpan]

bit bewildered by the i-ring, perhaps I'll look on youtube with the word 'gasket'!   2.5mm thick glass, and to be honest not sure about 39.5mm.  Fossil advising the wrong size has disheartened me, cheesed  me off a bit, especially as the rest of the project isn't going well.  I have no idea of the history of the watch, other than it ws found smashed up (see opening post.  For some reason, the hands touch  the internal ring with the angled indices that goes under the glass, the hands were bent, tricky to straighten, the hour hand wobbles like it's loose (maybe it is!), and with a new battery, upon assembly it refuses to tick - intermittent working is a fail.

Did Fossil advise that thickness as that seems way too thick to me.

Can you post a photo how the one you've got looks when in place.

[Nickpan]

[AndyGSi]

So you can tell compared to this that it's way too thick but does appear to have been glued.

Edit

Just found this on eBay which appears to be the same as Fossil advised?

I've been bingeing vids on people replacing glass on Fossils, Diesels and even Kors (all Fossil products apparently), but not seen any gluing or gasketting...

I've contacted the seller on eBay, asking the thickness, and if it'll need glue or gasket.   Thank you Andy!

[AndyGSi]

I've got a friend sending me a DZ1717 to look at so will have a better idea then.

First video I looked at and it's glued.

 

[Nickpan]

if I add the word 'glue' to my search criteria, I get a couple of 'glue the glass' results, but without that exrta word, not many suggest gluing

[Nickpan]

next issue!  What a learning curve...

It ticks for a couple of hours then stops. A quick tap starts it ticking for another couple of hours - knackered movement?  Hands turn freely when turning crown

received message from online seller, will need a gasket...they didn't have any, so I shall go to Cousins.

Gasket for what?
