The lowest-priced NOMOS caliber from Glashütte: You can wear the beautiful stainless steel ring (Ø 19 mm) either on your finger or with a leather cord around your neck. What time is it? Set the correct date in the middle ring on the hole, then, with the sundial hanging freely on the leather cord, turn it towards the sun so that light falls onto the hole. A ray of light on the inside of the sundial ring will show the time. Here in the version for the Glashütte area. What if you don’t live in any of the cities listed? You can ensure that the sundial still works accurately by selecting the city version that best approximates the latitude of your location.
