Water resistant Pocket Watch, Model 10109, 'Les Traditionelles', Cal. Unitas 6498
The Luminousity is excellent
Seeing "T SWISS MADE T" of course will make you confident that you see this dial also at night. However Tritium has a half worth time of ca. 12 years and will fade then. You can also see, that those hands are older then the dial. The lume on the hands had cracked and I had the watch sent back to Switzerland to change the hands.
It was not so much about the lume, but I was afraid that the Tritium bits could have reacted with the nice black matte dial and left ugly stains.
