Is this 390 battery lithium?

No. Battery #390 is a 1.55v Silver Oxide Battery

Is this the same as a V390 battery?

Is 390. V390 is discontinued w/some companies. Comparable to 1130SW, silver 1.55V.

Back of my Swatch reads: battery 11.60x3.10 1.55v but when I opened the battery cover, the battery reads 390 Renata. Would this battery work on mine?

Back of 390 Renata is 1.55v, used for watches and other devices. Not sure of other dimensions. Since name and number is specific, watch will function w/it.
