Just trying to get my head around how this works.
When the jaws (operated by the stop/start button and column wheel) are under the clutch and lifting it up - chronograph disengaged. Is the second wheel still turning part of the clutch?
This is x20 magnification. I can get up to x270 mag with an optional eye piece. X70 in current configuration which is great for looking at wheel teeth, jewels and hairsprings. Plus progressive linear zoom from x20 to x70. I love the well made piece of equipment. Sent from my iPhone using Tapatalk Pro
