Seiko refused to [service] my [SARB033]

Hello, everyone. I recently visited the Seiko service center to have my Seiko Sarb033 serviced. I’ve been wearing it every day for the past 5 years. The technician conducted a visual inspection and tested it on a time grapher. According to him, the watch has an amplitude of over 260, and the movement is in very good condition. He advised that servicing it now would be unnecessary and a waste of money. Instead, he recommended that I continue wearing it for another 3 or 4 years before considering service. Should I trust his recommendation, or should I seek a second opinion from another service center?
