Hi 🙂

I'm very happy to find your board, really 🙂 🙂 🙂

• I have 2 watches that need batteries that are missing and I don't know how to find which ones the need.
• 2003 Swatch Originals: Lady ; Strawberry Jam; numbers on the back read (#807; LK 243; 7,90; 3,10; 1,55V)
•  
• Citizen (Back 4-751043 S; 9040587; 46-0125) Front (7520-753795-Y)

That's all I can see.

Please help me find which batteries?

Also one more thing... Would someone be willing to school me in what all these numbers mean?, I am truly grateful if you would.

Thank you and very kindest regards,

Danielle
