On My Bench - Another Turtle

Case all cleaned and finish restored.

Pressed in the new crystal.

And then crystal bezel and top bezel.

All done, now to case it up.

That is pretty cool. Thank you for sharing.

It took a while to finish the power reserve test after a manual wind.
I got 7½ turns from flat until the bridle slipped which is about right for this caliber.

The auto wind assembly was then fitted ready for a final test.

And here we are, doing the rounds for a few hours.

Whoops!

Forgot to close off on this one.

Here is a snap from the results document.

And a little video so the owner can see his baby is doing just fine 😉.

I hope the music is acceptable for @rob#1

😁

Excellent, well done 👍, though you could have used any old music, you didn’t have to record yourself playing the piano 😉😁

So satisfying to see a watchmaker doing his job

Wonderful... loved the videos.
Quick question, I too have a 6306-7001 as well and the previous owner also swapped the original crystal for a domed sapphire.
You mentioned removing the AR coating, what do you recommend I use to remove coating or is it best to replace sapphire crystal with original?
Thanks

I polished both sides of the crystal with diamond paste (0.5µ) but the crystal still had a tinge to it, so it was replaced with a standard flat crystal.

Here side by side after polishing.

And at an angle with the reflection of my worklamp showing the bluish colour.

Thank you for your quick reply. Yes, I best source a standard flat crystal and replace the sapphire. It's funny, it didn't bother me initially, but then the hazy blue view just started driving me nuts. Beautiful work
