> It's pretty much physically impossible for a Rolex to still be within spec (+-2 sec / day) after a decade of use.

Neither confirm, nor deny. It's not my watch, I'm just the messenger of the owner. He said it's not opened. I can't say anything else.

> If the only reason you take your watch in for service is because the time is drifting a lot each day, you've waited too long.

For me a drift for service is a minute/day at most. Also, these are the words of the retailer I bought the watch from. They carry and service from Tissot to Omega, and everything in between for the last 20+ years, so I'm assuming they at least they know what they're talking about (Longines official recommendation is 6-8 years on their website, BTW).

> Your Seiko 5 can be cleaned and serviced (you can regulate it yourself with a Timegrapher you get on ebay for $100), but I'd probably just replace the movement with a new one. They are essentially disposable.

I'd rather not replace a japan made movement which constantly hits +/- 4 seconds every day, esp. if it's designed to be very low maintenance and repair. Of course I can upgrade it in myriad of ways, but I bought it for what it is, and I'd rather keep it stock. A 7S36C can be a very simple movement, but it's not exactly disposable.

I'm aware of the depth of the rabbit hole, and I'm making a conscious choice of staying at the surface, because I rather have less number of dependable items rather than a fleet which needs constant love. I've found the depths of proverbial rabbit holes in other ways, so I'm pretty experienced about the consequences.
