Another rarity.
Not the more common 600m dial, but the 600 dial.
Bezel insert and dial is in very good condition.
Case has some touched-up done onto it at some places (I have attempted to show this in some of the pics). Crystal is flawless. Screwdown crown works like a gem.
Bezel seems to be a little loose - would recommend a service done onto it.
Quickdate works as it should.
