This is one of the coolest "watches" we have carried.
This watch is the lowest-priced manufacture caliber from Nomos Glashutte.
You can wear the stainless steel ring (0.19 mm) either on your finger or with the included leather band around your neck.
How to Tell the Time
Set the correct date in the middle ring on the hole, then turn it towards the sun so that light falls onto the hole.
A ray of light on the inside of the sundial will show the correct time referenced to EST (GMT -5).
