700 crown / tube combo from Phong

[bones]

I'm confused, firstly the crown does not fit the tube. Do I need to broach the inner diameter of the tube to fit?

 

Secondly the crown has the triplock dots, surely this is very incorrect for the 700 which was twinlock?

You have either an older 703 triplock or a 702 twinlock and a 7000 twinlock tube. Won't fit.

I was under the impression the those dots under the coronet were reference to the metal/s used in construction.

Nope. Refers to the seals.

Not quite, it does have some bearing on it though.

You got both the crown and tube from phong?

Return it if they don't fit, cause they should!

And yes, 700 crown has no dots

Older Twinlock tubes often had to be broached, but, as others have said, you have a 702 crown, not 700

Grr, i wouldnt even have minded if he'd sent me the 702 combo, but one of each really isn't helping the situation.

This was the reply I got from phong

they are have both 3 dot is old style has been use for Sea-Dweller before and no dot newer style factory specs on tube 700 you have to use grind tools to install and use epoxy to seal or lock tight and after you install in use cutting burs to grind inside to 2.20mm to fit the crown. that factory specs. let me know if you are watch maker?if you don't know how to install let me know send to me I will do it for you just pay shipping Phong

Show me a pic of the inside of your crown, at the same angle where Freddy shows his trio.

 

See how the threads on the 700 go clear to the base on the inside?  That's unique to the 700.

Cheers for the reference photos/diagram Bone & Freddy, very helpful

ok this should help, this is actually gen spec 700 crown and tube , phong made these with the 3 dots which is incorrect, should have NO dots, but he will argue that fact, the tube will fit the crown, you will have to install the tube and then actually drill out the center of the tube so the crown will fit inside, the gen is like this also

It has threads that go all the way to the bottom of the inner crown, which would suggest its a 700.

Kind of defeats the purpose of having a 700 crown when it has three dots. But oh well, i knew it would need broaching on the inside of the tube.
