    What makes Oris, not just any brand, speed up or down?

    I've noticed that my other watches speed up as it loses power... But this oris seems to be the opposite, at least to me, it speeds up as it gets fully wound and it loses seconds as it runs out.. I've taken trips where I walked around 10+ miles a day in sighting seeing, and measured that the seconds consistently gained... During normal to little usage it starts losing seconds. Do you guys see the same with gaining/losing seconds on yours?

    My Oris with the Selita runs better on wrist. It usually loses about 8 seconds a day. Sitting static, it loses double that. It probably needs a service, but that's my experience thus far.

    I wonder if a service may be called for?

    it shouldn't, since it's 4 months old, but who knows? Do these watches typical gain or lose seconds as it loses power?

    Magnetism could cause it. Many use something like this to de-magnetize their watch: https://www.amazon.com/BQLZR-Mechani...935767&sr=8-15

    I don't have an Oris watch yet, but all my other automatics using the same movements continuously slow, with each week a little slower than the last. Even though I wear my watches 23+ hours per day, I guess my activity level is not great enough to always ensure a fully wound watch. I am going to experiment with my new Omega Seamaster Pro 300 week after next. Its deviation is so low that I only have to hack it once a month, but this time I will give it 20 manual winds at the start of each week. Maybe its losing trend will be reverse.

    Here is another data point. I recently purchased a Steinhart Ocean 1 diver. I wound it manually 50 winds to ensure a fully wound movement, then I set it dial up on my desk and let it stop, it power reserve was 44 hours. I then wound it up fully again and wore it for the next 3 weeks without any manual winding, I just let the rotor wind it like it is supposed to. After those 3 weeks, I set it dial up on my desk again; power reserve 34 hours.

    I am surprised at how sensitive daily rate is to a movement's wind state. I think the term to describe that effect is "isochronism". It is also the reason why quartz wristwatches are the superior time pieces.
