How can I change the battery in my MIYOTA Cal JS36 Stopwatch?

[Nigel]

While the MIYOTA Cal. JS36 Stopwatch manual may not detail battery replacement, here's a general guide. First, gather tools like a small screwdriver, ideally a watchmaker's set. Carefully find the battery compartment on the watch back, often a small, circular cover. Use the screwdriver to gently unscrew or pop off the back case, revealing the battery. Note the old battery type and orientation before removing it. Insert the new battery, ensuring correct placement as indicated inside. Reattach the back case, ensuring a proper seal to maintain water resistance. Finally, test the stopwatch functions and time settings. If uncertain at any point, consult a professional watchmaker or jeweler for assistance to protect your MIYOTA Cal. JS36 Stopwatch.
