Hi, I'm new to this forum and happy to be in the company of other watch enthusiasts. A few weeks ago I purchased a new Hamilton Khaki Field Mechanical (38mm, white face, H50 movement). So far I love the watch and I'm tracking it's accuracy for 30 days. I have 2 weeks of data so far and my average rate is -3.5 s/d which I think is pretty good. Would someone know what the Hamilton specs are for accuracy on this watch? Many thanks!
