I have a Timex Indiglo water-resistant wristwatch. It has 4 buttons: Set, Start/Stop, Mode, and Split/Reset. I need to find a manual to help me set the time and turn the beep signal on or off. I don't know the model number. On the back, several things are engraved: CR 2036 Cell WR 30 M 555 PP (none of these are model numbers, as far as I can tell). Hope this helps to identify the model and its instruction brochure. Please email me at sbernold@aol.com
