The Oris caliber 735 is essentially a Sellita SW200-1 with a custom Oris rotor with the recognizable red center (sticker?).

The Sellita logo and SW200-1 caliber number can be found engraved below the balance wheel. In addition, Oris also engraves “735 / 26 JEW” as well as “SWISS MADE / ORIS / HIGH MECH” printed on the rotor.

[…] BC3 line uses a Sellita-sourced automatic Oris Caliber 735 movement. 26 jewels are incorporated into the design in order to keep friction down and improve accuracy. […]

Oris Calibre 735, base SW 220-1 is not a very accurate movement, running well below COSC standards – quite a disappointment!

Mine runs at roughly +16 seconds daily… not exactly sure if I was lucky or if Rogers comment is broad brush for the SW-220. In my mind a sub $1000 dollar automatic running at this % of accuracy is hardly a disappointment. (Ref: 01 735 7641 4263-07 5 22 22G).

nobody buys a mechanical watch if they want accuracy even omegas master co axial chronometer isn’t accurate. If you want to tell the time precisely then buy a quartz

True. But it is great to have a hand crafted movement that is as accurate as possible. Especially if you are a watch lover of both craftsmanship and accuracy. the more accurate a analog movement is the more attractive it is. I have both makes Quartz and Automatic Analog

Grand Seiko spring drive – mechanic movement with quartz level accuracy but who would pay 5k plus for a Seiko?

I bought one and it runs at 0/+1s a day… its almost perfect, but as said, for accuracy just buy a casio quartz, or jump to the 5/6 figure price tags 🙂
