Casio W-71 working but buttons stick & Casio alarm chrono 1980's working no Back


Both are working, both have sticking side buttons but can be set manually, one has back missing GOOD MECHANISMS

The W-71 has a new band, i can use it, but i had to set the time day date manually with the mechanism out of the body, i took one of the little buttons out and cleaned it and it works, but i almost never got it back together so i will leave that up to the buyer of the other button, so i think 2 buttons work and 2 are sticking, i have the Military time set and date set, i dont see a light when i push but again that button seems to not be working correct but unsure

The other one i dont know the model number because it has no back, its working but buttons stick and i have not messed with it so unsure of all functions

''SOLD AS IS FOR REPAIR OR RESTORATIONS'''               BOTH I BELIEVE ARE MADE IN THE 1980'S
