Does anyone have any links to tutorial or guidance how to replace the crystal

Im used to working on pocket watches but a friend has asked if I can replace crystal in this watch for them 

Thanks

Sometime these pop out pressing with the thumb, it not use a crystal press with a shaped die. Then if there is no gasket just clean all around and apply a bit of crystal cement.

Note that if it's just about the crystal being scratched it's probably more practical to polish it in situ as that avoids both removing/ refitting and getting a perfect replacement.

Hi Esslingers watch site in the USA do tutorials for crystals and many other jobs as well .   worth a look

I have attached a pdf which describes where to find the full case number.  I have detail of 9 different crystal fittings for rectangular/square cases.  If you can find the case number as indicated the I can probably pull out the correct one and possibly the Seiko crystal number. 

As above, if it is plastic then easier to polish out.  If hardlex glass the can be done but much more difficult and easier to replace crystal if one is available (check out Sternkraus).

The case reference is in the title of this topic.

Worth to note that finding a Seiko crystal P/N on the websites of material houses like Cousins UK, Boley, ST supply, etc. doesn't mean that it's also actually available, or if it is, compared the overall cost is reasonable for the objective value of the watch.

Finally had a chance to trawl my databases.  Attached is Seiko Case Servicing Guide which covers all case types.  Full details for RO case is on pages 49,50 and crystal removal method on page 20.  Hope this helps.
