Case Serial No.:
1953 (L3 on case back and movement) Water Tite. I believe this to be the model with chrome plating and stainless back. Most of the plating has worn off revealing a more golden color underneath, especially on the back. Crown is heavy and signed. Radium hands and hour markers, did not glow after being exposed to sunlight or LED light. Red sweep second hand. Swiss below 6 o'clock. Inside case back reads "Bulova Quality". Back reads "Stainless steel back. Anti-magnetic. Shock resistant. Water Tite".
