Hi I'm new to arduino I'd like to know would this screen work
http://imall.iteadstudio.com/im120419001.html
With the mini pro arduino. I'm trying to make a smart watch if these aren't compatible please suggest alternatives.
Thank you in advance :)

would this screen work

Yes looks like it would.

However, unless you can find a library then you will have to write the code yourself which might be beyond you at the moment.

Edit.
Just looked at the web site deeper and there are libraries for the arduinio.

Part number is ITDB02-1.8SP
And it is on the Imall website

Wow thanks I've never used a forum before you've been a great help will this work with the pro mini arduino ;)

Yes

Are you sure as it isn't listed in the compatablilty

If it will work with an UNO it would work with a Pro-Mini but some Pro-Minis are 3.3V. That would be perfect for this display because it is 3.3V as well.  If your Pro-Mini is a 5V version then you may need to provide level conversion using a CD4050  or CD4050E , or 74LVC245 ic. All the pins on the interface are inputs. (see attached diagram)

SCL & SDA are I2C signal names and the description says it is serial so if you are not familiar with I2C you may want to learn something about that and you may (or may not) need 4.7k ohm pullup resistors on SDA (to A4) and SCL (to A5) which are shown in attached image

Yes but if you look at the sample code you will see it is not I2C, sometimes these names are used for SPI or SPI like interfaces because they are serial as well as I2C.
