I use to sell that kind of thing in a prior lifetime.
I dont' think you'd go wrong with one of those. However, if you like mechanical things (don't all tractor type?) You can also look at the Seiko "KineticQuartz".
It's a hybrid of an automatic watch and a quartz movement. The automatic movement moves a little generator and the power gets stored in a cell. And NO, you can NOT hook up your pto to this generator /forums/images/graemlins/wink.gif
Either will probably last a very long time.
On to the band, I'd suggest a two tone at most with stainless being the primary finish. If you get a "gold tone" band, it will in time, wear off and turn your wrist green (if you react to the base metal) You will not have to worry about a stainless band doing that to you. Look at the double locking clasps. After having one of those, I will never go to a "lessor" band. Lessor is not meant in a derogatory way (for those who have the "lessor" band). It's just that the double locking clasp is SO secure (mine has NEVER EVER "snapped open" in over 10 years) anything else just doesnt' feel right (to me).
me loving mechanical things, I'd steer you towards the Kineticquartz in either the stainless or if you like a light watch, titanium /forums/images/graemlins/cool.gif.
As a matter of putting my mouth where my watch is, I DO own a fully automatic "Chronometer" that is supposed to be good from "-0 to + 10 seconds per day" or something like that. (what ever the standard is, to get the Chronometer rating). One thing I like about it is the second hand sweeps on a seemingly continuous basis, rather than the intermittent "tick, tick, tick" of a quartz watch. Yes, I give up accuracy, but it's not a bother to readjust it every now & then and besides... (me being **** here) I really don't like to spend my lunchmoney on a nice watch and have the intermittently ticking second hand, stop in between the hash marks. By having the sweeping second hand, that is not an issue.
