So I didn't see my Riseman for 2 weeks now.
To make long story short, I moved 2 weeks ago to another block, about 1 mile from the old appartment, three watches were missing at the first check, my Tissot, my Riseman and my old Casio Illuminator, I later found my Tissot in the glove box of my car and last week I also found my Illuminator thanks to its hourly signal, but my Riseman is still missing.
You can't imagine how I missed it !
The only thing I can be sure about is that I saw my Riseman in the new appartment, so it should be somewhere here, maybe someone unintentionally thrown it in one of the card boxes and sealed it, the watch's alarm is set to 0600 and 1800, the hourly signal is also activated, that helped me to find the watch a couple of times before, but this time I worry that the watch has spent a lot of time in the dark and the alarm is automatically disabled. It means it's impossible to know where is it unless a complete search of the house, a thing that I can't do right now.
