Re: Accuracy of mechanical watches and break-in
: Hey Roger, I don't much subscribe to the notion that watches have a
: break in period. But if Seiko
: says it does, that's good enough for me. However, your post got my
: curiosity up a bit, so I took a
: look at some of the owners manuals for watches I own. Not a word
: about a break in period from IWC, Rolex
: or Union. Strange. I also looked in the owners manual for my truck,
: no break in period from Cummins. But,
: if they did specify one, I don't believe they would want to
: overhaul it after that period. Let me
: tell you this, it does run better the more milage there is on it.
: So, are you gonna send it to them after
: the break in is over? And, are they gonna charge you for this
: service? Thanks.......David
David: It's odd that your truck's manual doesn't specify a break-in period. Both Ford and Mercedes speak of break-in habits in the manuals that I have. Those Cummins engines are pretty tough, so maybe they need to be thrashed from the get-go! Rog.
