Post subject:  Tracking Breitling vs. iPhone clock
Hello Breitling Members,

I’m new to the luxury watch game, and recently purchased a Breitling (NAVITIMER B01 CHRONOGRAPH 43). It’s my first mechanical watch. I’m using the seconds hand on my iPhone to track the accuracy of my watch.

First, is that an appropriate barometer to use?

Second, I set the time Wednesday evening. It’s now Sunday morning, and my watch is 25 seconds ahead of my iphone.

Third. here were the following instructions to setting the time per the manual: Unscrew the water-resistant crown counter-clockwise.
1. Wind the watch by approximately 40 clockwise turns of the crown.
2. Pull the crownouttoposition2,turnitclockwisetoadjustthe calendar to the day prior to the activation date.
3. Pullthecrownouttoposition3.Turnthehandsforwarduntilthe correct date jumps into place, at midnight. Then adjust the hour and minute.
4. Pushthecrownbackintoposition1

In step 1, I wound the watch about 45 times. In step 2, I may have had the crown in position 3 instead of position 2 by accident. Would this have screwed up the watch?

Thanks for all the help. I know these are rookie questions.

Welcome and congrats on the Navi.

Answers -

1) Yes, an iphone is as good a reference time as any.
2) 25 secs in approx 3.5 days is a little fast for COSC specs (-4/+6 secs per day). It's a new watch though, so give it a couple of months and see how it beds in. If it's still fast (and more importantly, if it bothers you), then you could have it regulated by Breitling.
3) Unlikely to have caused any damage at all as long as whichever position the crown was in was correctly engaged. If in the unlikely event something did get screwed up, you'd soon know, so if the hands are running and the date changes each day at the right time, you've got no problems.

Tracking time using the second hand on your iPhone?

Nah — do yourself a favor and download the Emerald Sequoia “Time” app — which synchronizes with multiple atomic clock sources. I use it religiously... :D

Another very good iPhone app is Timestamp - you can zero the app with the watch's second hand, and then log future times when the second hand is on the 12, and it measures the time drift. It's great and I use it for logging the errors in my watches' times.

The Sequoia Time app is also great, but the big error here is logging the time the second hand passes 12, which can only be accurate to about 1/4 of a second with practise as you're doing it by eye and fumble finger.

Try timestamp, it's free!
