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.
