> Although it seems youd have to pay a lot to get an accurate one because I have a $250 mechanical Seiko and its time keeping is junk. It was mediocre when I got it and has gotten worse. It was $150 when I bought it so I suppose it would have been a good investment if it hadn't got beat up.

You know you need to service mechanical watches regularly, right?

A 7S26 movement (Seiko's mass-produced budget workhorse) isn't that accurate (I think -35 to +45s per day IIRC?). But if you paid $250 secondhand you most likely have a 6R15 or similar inside, which should keep between -15s to +25s per day at worst if regularly serviced. Often you can get much better performance from these movements than the specs imply.

But ... you need to service that poor thing. For a 6R15, every 5 years at minimum, but as an old watchmaker I knew used to say -- a watch will tell you if it needs servicing earlier. Sounds like yours has been trying to get your attention for some time :)

(Otherwise, it's like complaining that the Porsche you haven't taken to a mechanic in the last decade doesn't drive so well any more ...)

You will never get quartz accuracy from any mechanical watch, but that's hardly the point.

(The ETA 2824-2 movement in the page you linked to -- the movement that powers most mid-range mechanical watches -- is substantially more accurate than these lower-range Seiko movements, although it's more costly as well.)
