Economy of Scale

My watch stuttered for a week and it didn’t seem like a battery.
The watch repair man said it was solar, just leave it on the car dash for a day. “No charge”, he said. To return the favor I bought a pair of antique cuff-links from him. They are Roman lion heads in gold. Now I need to buy a shirt with French cuffs. Something in blue with a small stripe I think.
It would have been cheaper to buy a watch
