So I found this watch at a local shop. I cannot find ANYTHING about it. The model number on the back says SD050. This watch has a pretty cool face and looks EXACTLY like the Timex m433. On all these websites Spalding isnt even recognized as a brand. I literally just started collecting vintage digital watches and would love to know more about this one. It works great except the alarm I can barely hear and the light is dim, I just changed the battery so it cant be that. Do I need a new piezo transducer? I would love to get this watch back to its full functionality.
