Originally I was interested in the Tauchmeister T0021 with a black dial, but since I already own a Heuer Submariner with black dial and black bezel, me reitzte the "Night Diver" -Zifferblatt this clock. The clock was in a very nice sales package in the shortest time with me. The setting of the 24 hour GMT hand initially proved a bit tricky. It's best to wait up to a full hour (2,4,6,8 etc.) so that the pointer actually synchronization with the master clock. On vacation, it's a beautiful thing when you know that the family home is still or already in bed, if you want to call. If the luminous dial has been charged for a short in the sun or by a normal bulb, you can read the time in the dark significantly. The bracelet and case are heavy and give the impression of a high-quality finish. The engravings on the normally open and the back cover of the clock look dibasic. In the two weeks that I already have the clock, it is very accurate. The first contacts with water (bath and shower) has mastered them successfully. I would buy the clock again and am still zuzulegen another clock of this manufacturer, since the bracelet my Heuer is already more expensive than two watches of this manufacturer.
