I've never used watcher so I wouldn't know how to find out anything
there. But I assume you have a serial device (COMx, "modem" or
whatever) you could connect to using HyperTerminal. There you can get
signal values using the "at!gstatus" command. E.g.
Current Time: 15759 Temperature: 44
Bootup Time: 1 Mode: ONLINE
System mode: LTE PS state: Attached
LTE band: B7 LTE bw: 20 MHz
LTE Rx chan: 3050 LTE Tx chan: 21050
EMM state: Registered Normal Service
EMM connection:RRC Idle
RSSI (dBm): -66
RSRP (dBm): -101 TAC: 78BF (30911)
RSRQ (dB): -14 Cell ID: 01036700 (17000192)
SINR (dB): 15.6

I do not know if there are any correct answers to this. Lenovo would
probably say no. That's why they put the whitelist in the BIOS ;-)
But this is what I'm using with good results (with European 3G bands and
LTE Band 7 - I cannot test anything else):
MAIN - red
GPS - blue
AUX - beige
