Silver, Roy King.

[Speedbird-1]

Good day everyone,

I would like to remove the lacquer (recommended remover?) and gently polish this beautiful 1975 Silver Roy King watch.

Does anybody know how to safely open it? As you can probably see there is no 'back' to open, so the winder seems the only way in, though I'm loathe to 'force' anything, for obvious reasons.

I shall, of course remove the strap too.

When you remove the strap you should see a very small “scallop” indent, or small arced flange, on either the 12 o’clock or 6 o’clock end to allow a case tool to pry it the caseback open.

No screwdriver, only a smooth case tool.

Thanks Paul,
I've had a close look and it seems to be, what they call a 'front loader'.
(no sign of any 'split-case' arrangement)

That's fairly interesting. The best watch forum on t'internet, more than 300 'views', and no solution.

If the case cannot be split open like a Cartier Tank, and there is no caseback then it is indeed a monobloc 'front loader'.

Working on Rolex all the time means I have little experience with this stuff, but not none.
In a case like this you usually have a split winding stem, which means that with a little force you can pull it in half and have the crown with a part of the stem in your hands.
Then you'd have to apply some compressed air into the case tube, increasing the pressure in the case will pop the crystal out, allowing you to remove the movement.

Wow

I agree with the above, it’s a split stem with a pop out crystal.

Thanks for the info' Bas.
I'd given up hope, and hadn't seen your reply 'till today.
Don't have the equipment to apply pressure...any idea what kind of psi, d'you think will do it?
What size spanners will I need?
