Since synthetic Diamonds cost almost nothings, why aren't watchmakers using them instead of Rubies? Is it the added brittleness of Diamonds over Rubies? If so, is that really that big of a factor?

How do I account for the very short pause between two ticks?

Right now my ratios were straightforward with;

>1/8th rotation of the barrel every hour > 1 revs of the canon pinion > reduction gear > 720 revs of seconds pinion > 10:1 escape wheel (21600)

also, 1 revs of canon pinion > reduction gear > 1/12 rotation of hour hand

but after all was done I realized that the escape wheel doesn't constantly spin but ticks, so there would be some lost time in the stop and go.

Am I overthinking this or is there a formula for me to determine the tiny time loss that is occurring in my head?

Need watches to practice watchmaking. Need not be whole watch, just the movements are also acceptable.
