Amazing accuracy on a Submariner!

Yes amazing accuracy! I have worn my SD4k 24hrs a day continuously now for more than 40 days and it is off by only 2 seconds total! Check out the graph.

Great watch. Congratulations.

If the watch started fluctuating widely, then I'd be more concerned.

I can say, my Sub keeps time better than any other mechanical watch I've had and that includes my Master Co-Axial Seamaster 300, which unfortunately isn't in the same ballpark as the Rolex. I'd be interested to see if the new METAS standards hold their own against Rolex's Superlative Chronometer standards. My Omega is pre-METAS.

My Timegrapher will give me a + or - at all positions of my watches but will not give me even an idea of how it will keep time on my wrist.
I need to wear a watch for a working week in my normal pattern of 8 hours on and 16 hours off to give me an idea of precision.
Note I say precision and not accuracy.
From the time I sync a watch accuracy is reducing.

This is the best I can do as I change watches from Friday to Sunday.
