Timing your watches

[gsingh0317]

It's always interesting to see how many folks track their watches accuracy, what tools they use, what they consider an acceptable range for watches, and what they look/test for compared to someone like a professional.

What are your opinions on this?

For me, if I bought the watch and it was certified to run within a certain range, I would expect that for at least a few years unless I abused the crap out of it. I use the Watch Accuracy Meter app for timing most of my pieces, but it may be time to upgrade to the timegrapher's that everyone uses.

One thing that was shocking to me, the accuracy of a watch can vary wildly depending on the orientation it's in, it's something I had to learn. We had a watch accuracy competition at our local watch club and an Oris took the crown with +1s average in 6 positions but the Omegas/Rolexes were choking on some of the positions, granted they were a few years older. A freaking Tissot Le Locle was at +0s at certain positions.

For average observations I have relied upon a website.

www.time.is

The source atomic reference clock doesn’t drift, but the internet delay can vary by an unpredictable ms loss.

I use an atomic clock app on my phone.

As long as the performance is close to spec I am happy. I use it to gauge if the watch is in need of service, not to split seconds

Interesting! So basically when you see your watch go from +1-3s a day to +15-20, you're thinking it's time to at least demagnetize or service the watch.

Oddly, I don’t obsess about timekeeping. I do about scratches though, overly so

I’m more focused on timing when a new watch comes in to make sure there aren’t any initial issues with the movement. After that, I’ll check every few months when I’m resetting the time, due to enough gain/loss that makes a difference to useful timekeeping.

I set my watches to time.gov, wear them for a week, check time.gov again and see what the average gain/loss is per day; that way I’m tracking normal use, including nightstand time. If I see a significant deviation to the stated accuracy, off it goes for a service.

Works for me.

I use an iOS app called “Movement - Watch Tracker”

It has a convenient interface where you can track the accuracy of your whole watch collection by logging data points over time. It works very well for me.
