This is just an FYI for anyone interested, as this is a controversial subject and some people care, others don't
Information on RF/SAR rating is here:

The SAR rating in itself provokes different opinions from experts, but its all we have at the moment in terms of controlled and consistent measurement
There is evidence of tumor growth on test rats treated to steady MW/Cellular radiation, albeit at amounts typically larger then would be received from a mobile/cell phone. There is also evidence that MW/Ceulluar radiation can speed growth in tumors already in existence.
RF radiation obeys the inverse square law. Basically as the gap between the emitter (e.g. watch) and receiver (e.g. your body) increases the radiation absorbed rapidly falls off. As the Apple Watch is held next to your skin its actually continuously closer more then a cell/mobile phone typically would be. This is why I also recommend when folk are talking on their mobile phone to keep a small air gap, even a few millimetres, with their head, as this dramatically reduces any absorption as compared to touching.
The risk from the watch is probably small but worth knowing about nevertheless.
My watch is the A2008. As expected cellular RF is almost three times wifi and Bluetooth, the results are (these are max values observed over a time period and at pre-determined distances - see the link above for more details):
LTE/4G 0.36
Wifi 0.14
Bluetooth <0.1 (probably around 0.10 considering measurements of other models)
My procedure is to:
1. Have on airplane mode when I am sleeping and also when I am at my desk at the office as I have my iPhone and iPad available
2. Have wifi switched off when out of the house as its a useless step (at work the personal wifi network has a signon system which the watch can't cope with)
3. Have cellular off unless I am without my phone. Typically on when popping out of the office during the week or at meetings.
I am sure everyone's mileage will vary
