Speedy Tuesday, a week from the start of the "highly technical and scientific" watch accuracy test begun last week.
It appears that the Orient Kamasu diver is gaining on the Speedmaster which remains quite constant ... well, in line with the computer's clock. The Orient appears to gain about two minutes per week. Not quite the required accuracy for my purposes as a "travel watch." Still, good enough for most of my purposes. I love not obsessing about mere seconds. I might have it regulated by my watch smith ... or might not.
