This is a Seiko stopwatch I purchased about 5 years ago. The stopwatch functions, but I can't seem to set the time correctly (it might be my technique), so I've only used it as a stopwatch. It comes with the instruction manual. Please understand that this is a used item, and I'm selling it "no claims, no returns." The following is an AI description: A SEIKO digital stopwatch with solar power and 300-memory function. - Brand: SEIKO - Model: S806 - Features: Solar powered, 300 memory - Water resistance: 5 ATM - Display: Digital display - Accessories: Instruction manual, case, strap Thank you for looking.
