As many of you will know I have been taking readings on my Sub-Date 126610 with a TimeGrapher.
I have logged those results on a spreadsheet and saxo3 kindly converted them into a graph for me and all to see. Seeing the results displayed on a graph is so much more clear as to what is really happening.
Since taking the readings on a TimeGrapher I have also taken readings on an App on my iPhone called WatchTracker. This is done by tapping on the screen when the second hand of your watch reaches a certain point. it is super simple to do.
There are clear differences in the amount of data you can get but there are clear similarities also.
It is a very interesting way of comparing different methods of timing a watch.
On the TimeGrapher it showed the x to be +0.2spd when fully wound and x to be -0.4spd after 12 hours.
On the WatchTracker it showed an average loss of -0.4spd.
Of course my Sub-Date with a 3235 movement is self winding (aka automatic) but I am fairly static all day. I do go for daily walks with my dog but I dont swing my arms much.
I therefore can accept that my Sub-date is not fully wound most f the time and the loss of -0.4spd is probably correct on BOTH the more precise TimeGrapher and the app on my phone.
I thought that was very interesting.
I attach below the spreadsheet and WatchTracker report sheets.
I can thoroughly recommend BOTH methods as they have proved to be so similar.
