Good Evening WUS,
I picked up a Navitimer 01 a month ago and it's running slow on me. -2 to -3 seconds per day on the winder. -7 per day when I let it run 48 hours without wearing it and about +1 per day on wrist. Like I said I've only owned it a month and it's not my only watch I wear so I haven't monitored it long enough to form an a full view of how it's going to perform for me but out of my sample size of 5 chronometers the Navitimer is showing by far the most swing between winder, wrist and at rest. Also it might run slower if the Chrono is running but I'll have to do some longer term checking to confirm.

So anyways I guess my questions are
1) How is your in house 01 or 01 derivative performing? Out of box vs now if different?
2) Does running the Chrono have any negative effect on time keeping for you?
