Tactix delta display difficult to read without backlight

Hi, I recently bought Tactix Delta and I am dissapointed with weak visibility of display without backlight on. I was (and I still am) impressed with the design of the watch, I invested to watch much more than I planned, I was looking something I can wear whole year round, outdoor sports, casual, but also in the office, for important business meetings, etc. Tactix are exactly watches for all purposes. But the display is very very difficult to read, especially indoors. Looking on the watch direcly I can hardly see what they show. Is there any possibility how to increase brightness of the display without turning on backlight?

Thanks,

Martin
