I thought about posting this in the Hamilton forum but figured it may branch into a more generic direction which would be better suited for the public forum, forgive me if I guessed wrong.
I use the ETA 2824-2 as a direct example as I know it is used in a number of Hamilton pieces but the question may extend to other movements use by Hamilton that I havent looked into.
The 2824-2 comes in three variations:
Standard Grade is adjusted in two positions with an average rate of +/-12 seconds/day, with a maximum daily variation of +/-30 seconds/day.
Elaborated Grade is adjusted in three positions with an average rate of +/-7 seconds/day, with a maximum daily variation of +/-30 seconds/day.
Top Grade is adjusted in 5 positions with an average rate of +/-4 seconds/day, maximum daily variation of +/-10 seconds/day
...which of the three does Hamilton use for their pieces? If they vary, I guess my specific question would be which is used in the Viewmatic line?
Im having some fun playing with the accuracy of my new piece. It is currently running -4 seconds per day with wearing it 24/7 and Im wondering if I stopped wearing it at night and started resting it in a certain position if I can get it to gain back those 4 seconds and reflect a zero deviation over a 24 hour period.
Side question, do pieces usually speed up or slow down over time? I've read some posts where people have said their watches started off +15 but settled after a couple of weeks to +7 or so... Im hoping that in a couple of weeks my piece doesnt slow further from -4 to something like -20 s/d.
