Looking good, fellow Monte owner

Your build sounds a lot like mine. Except I just tracked all of the
parts down and had a full service and build done by a professional.
I do not possess these skills but wish I did. Here's my beautiful movement
I got lucky enough to snag:
It's a 70's Heuer that was a 30 minute chrono but I found the 3 parts
needed to convert it to a 45 minute one.
My full service:
Same hand configuration as you, Yuki hands for Hour, Minute and Center, DW Chrono hands that still need the centers changed to white. I had the center hand shortened and I still need to cut-down the hour hand a little bit as well.
Love wearing my Monte
Dave...
