You said, "I have a Hamilton Model 23 Type 5747-1 Navigational Watch. That watch has temperature compensation built into it. That is what I was describing/telling a poster over there. No other watch comes close." The Hamilton navigation watch is as good as it gets. It has a flat balance spring instead of the heliacal one in the Hamilton 21 chronometer and doesn?t have the fusee chain drive. It can be regulated unlike the 21 and is poised in, I think 6 positions unlike the gimbaled 21. You have a regular watch escapment instead of the spring detent escapment in the chronometer. It is much more rugged then my 21 and I wish I had one to use on my boat. Robert Gainer
