Well, strike two on finding a crystal for my '53 Fat Arrow.
May 07 2008,12:57 PM

I was told by a couple of milwatch folks that the CK2914 railmaster crystal would fit the CK2777 fat arrow...

NOT.

The armored ring is way, way too wide.  It actually overlaps the tips of the hands.  And the crystal diameter is a little too small. 

If anyone has an idea where I can find the right crystal an email would be appreciated.

TIA.

Standard armored plexi...

Hi Chris,
there's no big secret, I'd say.
Standard armored plexi crystals are availlable in several versions - at leat a major european supplier the
types are something like, ATC (armored standard, chromium ring), ATCH (high domed), ATCR with modified ring (stepped underneith for more dial space), ATCB with wider ring (something like the railmaster, but not that wide).

Take a good caliper and measure the inside diameter (for the crystal seat) and order the plexy in that precise diameter.
Increments are in 1/10th of a millimeter.
Must be pressed in with proper tool - if unsure about proper measurement, order three of them +/- one tenth and you'll be sure to find the fitting one. They're not that expensive, having two left ove will not hurt

best regards
Suitbert

Sorry for not replying with infos as I'm a newbie here.

I hope you can find the correct parts for it and stay persistent, as not so many are lucky enough to come across such rarity and history.

Would love to see pic of it in the future if you can.

Good luck hunting!
