I had a marvelight it was really good for the simple reason that the tritium lume is so strong yiu can almost read a book by it. I really miss waking up in middle of night and being able to see the time without a light that wakes me up and then I can’t go back to sleep. If ball had an engineer cosc in 36-38mm I would buy again. I ended up selling my marvelight as it needed repair, but to be fair, I was wearing it surfing all the time and it’s not really designed for that

Nice review I really like the accuracy your getting .
