So my 19 hr accuracy check after receiving a new Orient watch at 7:00 last night showed I had gained 8 seconds in 19 hours. Understanding that, to quote fromm a previous thread on accuracy that:
"many factors can affect the accuracy of a mechanical watch, including ambient temperature (the colder it is, the faster it will be, as the mainspring contracts, shortening the amplitude of the beat/ the warmer it is, the slower it goes), centrifugal force, shock, state of wind and position it lies in"
I thought I'd describe the conditions I have been wearing the watch to elicit thoughts on whether I should expect different performance when I correct one or two things.
I wore watch all night last night to include while sleeping so It was largely stationary. This morning, 12 hrs in, watch seemed still to be 8 seconds or so behind NIST time, where I set it.
I rode my bikle to work so I wrapped watch in a shirt inside my bike bag. Though cusioned, suffice to say that it was more prone to jostling than it would have been while I was sleeping. It was also 35 degrees outside (although probably y stayed pretty warm in my bag). Around 10:00, I noticed watch had gained about 4 seconds on NIST.
I have not yet had the bracelet sized so it slides around my wrist quite a bit when I move. From 10:00-12:00 I was pretty stationary at my desk and watch did seem to gain any time. Then I went to meeting that had me leave my office, get into car, walk quite a ways, and sit in a very warm conference room. By the time I returned at 2:00, watch had gained an additional 4 seconds so is now spot on with NIST.
SO question, what effect do folks think jostling and jangling that occurred while biking and because bracelet is loose had on performance so far?
