This watch is really about showing off the new in-house caliber 113 movement (as you could probably guess from the name of the watch itself). The caliber 113 is based on the caliber 110, which was Oris’s first modern in-house movement, released back in 2014. Central to that movement was the 10-day power reserve, which is carried through to the caliber 113 too. This all comes from one massive barrel that sits up around 12 o’clock, and looking at the caliber you can’t miss it. Finishing overall is nice, if not ornate, with a lot of emphasis placed on making the winding works visible, which makes a lot of sense for this movement.
If you look closely, you’ll notice that there are no calendar correctors set into the caseband or lugs. That’s because all of the functions can be controlled using the crown. This might not seem like a big deal, but it makes setting a watch like this much easier and its the far more elegant mechanical solution. I give Oris a lot of credit for developing the movement this way.
