Accuracy Test

Unscientific test of accuracy.  Each watch was placed face up and allowed to run for 24 hours. I set them to the clock in OS 10.9 which is automatically updated.  Here’s the watches I chose:

 

The Tissot PRC 200 with the Powermatic 80 movement.  As the picture shows, it is near perfect.

 

Next, the Tissot Luxury Automatic with the Powermatic 80 movement, once again.   It looks to be 4 seconds slow.

 

Third is the Deep Blue Fleet Admiral wit the Miyota 9100 movement. It is 5 seconds slow.

 

Fourth is the Orient Star Retrograde with the 40A50 caliber 22 jewel movement:

 

Next,  mid 60s Longines with a 17 jewel movement.   It looks to be about 11 seconds slow.

 

Lord Elgin with 760 automatic movement, serviced late last year.  It is about 13 seconds fast.

Finally, an Elgin with the 761 movement.  It was about 30 seconds slow.
