Singe hand watches are very unique in style and are getting quite popular amongst those that are living in a more relaxed pace when accurate time reading is not very crucial unless you are a heart surgeon and need to get to the operation room just in time. Some One Hand Watches come with a super slow hand which rotates fully once every 24 hours, and most models are with slow-hour hands which rotate once every 12 hours.
Normally the indices between the hours represent minutes, quarters and half hours. By looking at the one-hand watch you can tell the time within a +/- 2 to 5-minute discrepancy.
Here is an interesting Single hand watch that Ferro watches created. This particular design is inspired by the classic Le Mans race
Reading the time with a single-hand watch is easy.
The 12-hour dial is divided by 144 marks. Each mark represents 5 minutes.
The combination of the bold 15, 30 and 45-minute marks and the prominent needle pointer makes it easy to read the time.
Below is an example showing different times.
