Thread: Seiko 7c43 crystal source

    Seiko 7c43 crystal source

    Does anyone know of a source for a crystal to fit a seiko 7c43-7010?

    Mineral or sapphire?

    I asked around not that long ago... there are some crystals that fit from eBay sellers. But nobody making 'correct' reproductions of the OEM crystal.

    You may find a NOS Seiko part poking out of a rocking-horse pile somewhere in the world if you are very very lucky.

    My 6309s should fit, ground bevel, correct angle bevel for 6309.

    Thanks both.

    Based on my limited research I thought the 6309 crystal prevented the crystal retaining from being screwed down correctly

    I had assumed someone was making the correct sapphire but perhaps not

    Can you measure 7c43 bevel angle?

    The 6309 crystal doesn't fit the 7C43 as you said Bob due to the different profile to accept the screw down crystal retaining ring.

    I think I have a 7C43 crystal in my parts box. I'll check.
