So I just made a deal here in the sales forum and got an Orient Mako. This will be my first mechanical watch in ages. I'm curious, as I plan to use this watch as an everyday watch/beater for a VERY long time. On a lower-end entry level movement like the one in the Orient, for how long can I expect it to keep decent time without a service? I've heard of watches like Rolex's and Omega's lasting a full 50+ years without one, but those are generally higher quality more complicated movements. I'm asking for a lower end Japanese automatic movement. I'm think maybe 15 years max before it starts gaining and loosing a dramatic amount of time daily. What do you say?
