Today I started servicing an epic 6105-8110. The owner wanted a new crystal,dial, bezelinsert and hands.
I could convince him to keep it original, and only change the old crystal for a new sapphire.

Not bad. Liftangle was not set right, but later on it measured 210 degrees.

  1. Hello john.

    I have a Seiko 6105-8110 serienumber 130539.

    I think its frome 1971/1974 ?

    I want the watch to keep original and only replace the glass fore Sapphire. And i think the watch needs a good glean up.

    Its not working but its compleet original.

    I live in the neatherland and hope you can help me with advise.

  2. Needs some lume pouring in to the hole at the top of the bezel, but apart from that the condition wouldn’t bother me at all; degraded glass does though!
