Hello, dou you know which communicating interface is used on these mbw watches? SSD1300 can use Parallel and SPI interface, SSD1303 (tested by me in mbw150 - picture was mirrored) use SPI/Parallel/i2C and SSD1306 interfaces are same as on 1303. New displays 96x16 uses ssd1306 with limited pinouts only to i2c.

Inside MBW-XXX watches is same ic - Philips/NXP BGB203xxxxx. This ic use for communicating I2C...BUT original display with 1300 does not have I2C...so how is it possible?
OR can be this original be connected via GPIO?

...this is interesting. I have found wiring diagram of original Ritdi display with SSD1300. It looks like it is really connected via i2c...BUT again after measuring on mbw-150 mainboard are both data ways connected to GPIO pins of bgb203 and not to i2c.

It is hard...i will risk it and i will test to connect chinese display directly with wires
