This watch uses the temparature difference from the skin (backside of the watch) to the air (frontside of the watch) and generates a current to liad a rechargeable battery (Leclanche 4106, 1,1V), which in turn drives the quartz movement. So (theoretically) you never have to change the battery. Date of production 1982 (P2), Signed front: “Bulova, Thermatron”, back: “ Bulova Watch Co, P2, Swiss, Water Resistant, Stainless Steel Back and Bezel Ring, 10652461”.
The rechargeable battery was not very reliable and Bulova stopped selling the watch and sold all surplus to a company called STW They modified the circuit and used a capacitor instead of the battery. See STW Thermatron.
