Thank you for your compliments, Art, and your question, of course: Indeed, it is a bit difficult to exactly set the correct time due to the oversized hour markers and missing minute markers as a consequence. For example: It is easy to accurately set the time at 10:05 minutes, 10:10, since it is easy to exactly align the minute hand with the hour markers at 1 and 2. Also there is no problem at 10:07 and 10:08, because of the hand's pointed tip and the large minute markings. Yet the markings at 10:06 and 10:09 are consumed by the large hourmarkers, so it is better to wait a minute for accurate setting.
The hack second is a feature integrated into the 2892 base movement, an indirectly driven small second - thankfully - does not affect that. I agree that a hack second should be a matter of course on all chronometers. However, there are chronometers without hack second, just think about the Zenith Primero chronometers, or the Ebel chronograph chronometers.
