Last week we showed TimeTracker for iOS, a nifty little app that tracks the accuracy of your Rolex over a period of time.  This week’s app, WatchDrift, has a similar function as TimeTracker, but it provides some different functionality and it runs on a Mac.  WatchDrift is a relatively simple app designed in 2011 by Map-It software and is available in the Mac App store at http://itunes.apple.com/us/app/watchdrift/id423779514?mt=12&ls=1 for $1.99.

 

Both TimeTracker and WatchDrift provide the same functionality for tracking the mechanical watch accuracy.  Over time, gravity and friction are what affect timing accuracy. Being a mechanical, your Rolex utilizes precision watch pinions and staffs that run on synthetic jewel bearings lubricated with oil. Over time, friction wears away oil and the added friction wears that staffs and pinions that hold the mechanical gears in place. Combined with gravity from wrist/arm movement, the excess friction slows a watch.  Many watchmakers recommend as soon as a watch runs slower than when it was purchased new, that its time for the watch to be serviced.

 

WatchDrift is a fast download as it is only 1.6MB.  Once installed, open WatchDrift and you are presented with two panes to enter data. The pane on the left is where you enter information about your watch (or watches if you have more than one). WatchDrift can track multiple watches. I entered both my Rolex Explorer II and my DeepSea SeaDweller.  The pane allows you to store other watch specific information, and the ability to add a representative image.

 

 

The right pane is allows you to add new timing runs.  Hit the “+” sign and add the time from the reference time listed in the app. Hit the “calculate” button and the amount of drift between actual and reference time is stored.  Highlight all the entries in the right pane, hit the “calculate” button and all the time points show on the graph.   The graph is exportable as a CSV or .pdf file which makes it easy to store or email graphs.

 

WatchDrift is pretty straightforward app to use although I did find myself guessing as to which time is entered into which field.  The potential dealbreaker  with this app is the lack of support or directions.  Despite this drawback, the experimenting to understand the steps did not take too long.

 

WatchDrift is a good tool for watch loving MacOS owners and once the steps are understood.  Tools like WatchDrift and TimeTracker are good to have in the arsenal for accurately measuring time drift, and knowing when your watch should be serviced. The other added advantage to TimeTracker and WatchDrift is that it give you a legitimate excuse to stare at your watch.
