I wore a Tissot automatic watch for more than 30 years.Serviced twice, now broken. A Rolex, used ~20 years, serviced once. Still running. Yes mechanical watches are machines, albeit small. I use a Resmed CPAP which has been running at least 8 hours every night for about 7 years. Never serviced. A '92 Volvo with >300K serviced frequently running fine. Might outlast me.
Another common machine used frequently early,then occasionally, now broken. Requires chemical assistance.
