I've seen some "chinese versions" that claim to work.

This one (from what the seller told me) supports even the SMS notifications and reply, which is quite amazing, since the SMS notifications and reply is the most difficult part on a smartwatch that supports WP.

Another smartwatch that claims to work properly (except for the SMS and some notifications if I am right)

About this one I am not sure, didn't manage to get in touch with the seller, but there are good and bad reviews so I am not sure what to say unless someone actually used it.
This one is French:
Smartwatch Montre Connecte Simax S1 Bluetooth Android Windows Montre Connectee | eBay
Talked to the seller and he ensured me that everything works with WP 8.1, except for the sms notification and reply.
I listed a couple that seemed interesting to me. The French one seems way more reliable, it is also a brand, not a Chinese version and has camera as well, but the main disadvantage (as it is with the main WP smartwatches) is that it does not support sms/notifications. On the other hand, the "ZeWatch3" seems to fit my needs better and I asume it is a hight quality watch as well. Am I right/wrong, please advise me.
If any of you know something more about any model listed above, or has some intel that might be usefull, please tell me. I'll accept your advice. Maybe you had experiences with some of those watches or know any good reason to buy one of them (or NOT to buy it).
