I am doing for SH3 a replica of a Hanhart pocket chronometer, and not just that one but also many other models from other Kriegsmarine contractors (F.e. Huber) seemed to have divisions for a decimal minute (A minute divided in 100 parts, obviously 0.6 seconds each). Is there any nautical use for the added precision? Why would they want to have such a dial, besides the normal 60 seconds one? AFAIK only time study disciplines for industrial applications have any interest in that, but is there a nautical use of it?
Thanks
