Opening Seiko 1944-0011 by the glass (One-piece-2)

[nico]

According to the Seiko's Casing Guide, This watch should be opened by the glass, with a S-12 or S-14.

I struggle to open it with a cheap glass opener, but it doesn't move. I tried to heat it with a hair dryer or put it outside by 0°C, without result. I also tried to turn it like to unscrew, it just make suffer this beautiful watch... So I'm stuck now, looking for an advice.

 

Note: There is no external bezel to remove, no notch anywhere, it's an true oyster

According to the instructions for the  S-14 the bezel should be removed. I believe this is a bezel.

Can you post a good close up pic of the watch side on to show the profile of the crystal and case, and also a pic of the back of the watch to show all of the text.

As @RichardHarris123 says I think that you probably do have a bezel.

Seems that you need to read the instruction manual for the Seiko one-piece case opener. As it's a glass with a tension ring, I assume it's acrylic, so your opener should work.

Thanks for your replies.

The glass is in acrylic, the tension ring seems to be high (but I'm not experienced) :

And as I said there is no bezel (the doc says it can come without bezel, like this one I guess.

I used my glass remover on another watch and removed it without squeezing strongly. But for this one I tried many time, each time screwing the tool harder.

I don’t think you can use this type of crystal list for crystals with a tension ring. Iirc the S12 and 14 tools are like a ring with handles that will allow for much more tension to be applied.

the seiko tools are illustrated on this page.

Thanks for your reply. It was one of the two options I thought ;

1. The glass has been glued in an improper way

2. I'm not using the right tools

If you're right, this one will be left in standby for now. It's not a problem since I'm not ready to work seriously on this one.

If someone in VD/GE can help me with the the right tool let me know

[tomh207]

Not sure where VD/GE are on the globe? I certainly would not expect glue to be part of this equation, so 2 is your most likely option.

I removed a tension ring crystal with a crystal lift while servicing a front loader. Starting around 4 minutes. Narrated in Finnish so not much help for anyone

VauD and GEneve are cantons (states) in Switzerland

That's exactly what I've tried to do -with a cheaper tool- but even with all my strength it doesn't move. Maybe the tool is too cheap...

Worked fine with the right tool: Seiko S-14
