Can I reset or backup my Gear S2 back a couple of days?

[Android Central Question]

I lost my old phone that my Gear S2 was synced to and realized all my phone numbers where on my watch. Before I could write all them down I synced it to my new phone with less phone numbers and now my watch has the contacts list and not my old one.
Can I back up the watch a couple of days and find my old contacts list again?
My old laptop would do this when you backed it up and would go back up to 6 months prior.
I never put any info on cloud so that's out of the question. I saw the other similar question and saw your response, but I already synced to my new phone thinking my old contacts would go to my new phone....
Any and all information will be greatly appreciated!!!
