Iphone 7 & Tag Heuer Connect Smartwatch

The reviews I found online seem to indicate no, iOS does not support all features (forum at calibre11.com has the most extensive review it seems). But those reviews also were at least a year ago, so may be behind what is supported now.

I would contact TAG Heuer about it, or I thought they have their own hosted support forums (but I cannot find them). Also try posting on calibre11.com, watchuseek.com as those are two of the oldest and most comprehensive watch forums around.

You might ask that watch manufacturer's support team. They should be able to give the appropriate answer about compatibility.
