Hi, everyone!

I was looking at a picture of an EB1297 watch movement and in the read up it says that the watch has "an engraved adjustment minutery on the dial side."

I can't even guess what this means, but do you know?

Thanks.

Len.

Dial side of a FHF150 showing  15 minutes worth of engraved adjustment minutery.

Completed watch movements would come off the production line and be fitted with a test minute hand. The movement would then be regulated by observing the transit of the minute hand over the engraved timing marks through a microscope and timing against a know source. The test hand would then be removed, and the movements put into stock ready to be matched up to any of the various combinations of dial, hand sets, and cases that were in the makers catalogue, or shipped out as bare movements to another maker.

Well, I'm blowed!

Thanks for that information, Mark, I find it totally amazing.

Slowly, but surely, I'm gathering more knowledge about 'what makes a watch tick.'

Again.................."thanks."

Len.
